AWS CDK database queries in PostgreSQL and MySQL

With support for the AWS Cloud Development Kit (AWS CDK), AWS are now able to connect to and query your current MySQL and PostgreSQL databases. This is a new feature that allows you to construct a secure, real-time GraphQL API for your relational database, either inside or outside of Amazon Web Services (AWS). With merely your database endpoint and login credentials, you can now construct the full API for all relational database operations. You can use a command to apply the most recent modifications to the table schema whenever your database schema changes.

With the release of AWS Amplify GraphQL Transformer version 2, which was announced in 2021, developers can now create GraphQL-based app backends that are more feature-rich, adaptable, and extensible with little to no prior cloud experience. In order to create extensible pipeline resolvers that can route GraphQL API requests, apply business logic like authorization, and interact with the underlying data source like Amazon DynamoDB, this new GraphQL Transformer was completely redesigned.

But in addition to Amazon DynamoDB, users also desired to leverage relational database sources for their GraphQL APIs, including their Amazon RDS or Amazon Aurora databases. Amplify GraphQL APIs now support @model types for relational and DynamoDB data sources. Data from relational databases is produced into a different file called schema.sql.graphql. You may still build and maintain DynamoDB-backed types with standard schema.graphql files.

Upon receiving any MySQL or PostgreSQL database information, whether it is accessible publicly online or through a virtual private cloud (VPC), AWS Amplify will automatically produce a modifiable GraphQL API that can be used to securely connect to your database tables and expose CRUD (create, read, update, or delete) queries and mutations. To make your data models more frontend-friendly, you may also rename them. For instance, a database table with the name “todos” (plural, lowercase) may be accessible to the client as “ToDo” (single, PascalCase).

Any of the current Amplify GraphQL authorization rules can be added to your API with only one line of code, enabling the smooth development of use cases like owner-based authorization and public read-only patterns. Secure real-time subscriptions are accessible right out of the box because the produced API is based on AWS AppSync’s GraphQL capabilities. With a few lines of code, you can subscribe to any CRUD event from any data model.

Starting up the MySQL database in the AWS CDK

The AWS CDK gives you the significant expressive capability of a programming language to create dependable, scalable, and affordable cloud applications. Install the AWS CDK on your local computer to begin.

To print the AWS CDK version number and confirm that the installation is correct, use the following command.

Next, make your app’s new directory:

Use the cdk init command to set up a CDK application.

Add the GraphQL API construct from Amplify to the newly created CDK project.

Launch your CDK project’s primary stack file, which is often found in lib/<your-project-name>-stack.ts. Add the following imports to the top of the file:

Run the following SQL query on your MySQL database to create a GraphQL schema for a new relational database API.

$ cdk –version

Make sure the results are written to a.csv file with column headers included, and change <database-name> to the name of your schema, database, or both.

Run the following command, substituting the path to the.csv file prepared in the previous step for <path-schema.csv>.

$ npx @aws-amplify/cli api generate-schema \

    –sql-schema <path-to-schema.csv> \

    –engine-type mysql –out lib/schema.sql.graphql

To view the imported data model from your MySQL database schema, open the schema.sql.graphql file.

If you haven’t already, establish a parameter for your database’s connection information, including hostname/url, database name, port, username, and password, in the AWS Systems Manager console’s Parameter Store. To properly connect to your database and run GraphQL queries or modifications against it, Amplify will need these in the following step.

To define a new GraphQL API, add the following code to the main stack class. Put the parameter paths that were made in the previous step in lieu of the dbConnectionConfg options.

This setting assumes that you can access your database online. Additionally, on all models, the sandbox mode is enabled to permit public access, and the default authorization mode is set to Api Key for AWS AppSync. You can use this to test your API before implementing more detailed authorization restrictions.

Lastly, launch your GraphQL API on the Amazon Cloud

Select the Queries menu along with your project. The newly developed GraphQL APIs, like getMeals to retrieve a single item or listRestaurants to list all products, are compatible with your MySQL database tables.

like instance, a new GraphQL query appears when you pick objects that have fields like address, city, name, phone number, and so on. You may view the query results from your MySQL database by selecting the Run button.

You get identical results when you run a query on your MySQL database.

Currently accessible

Any MySQL and PostgreSQL databases hosted anywhere within an Amazon VPC or even outside of the AWS Cloud are now compatible with the relational database support for AWS Amplify.

Do we Need a Server?

This week, I managed to finish the sketches for the login screen, but most of the day was spent experimenting with AWS Amplify.

I found AWS amplify while searching for an AWS service that could help me with authentication (login/sign out) for the app. Authentication and security are very serious topics when it comes to building applications. While I can build the authentication system from scratch (I’ve done that before), It’s a lot of work, and it’s not as secure as something that a large company like Amazon could provide. Cloud services providers like AWS and Google also offers the option to login via phone number or social media platforms which can be convenient. These are the major reasons wy I decided to look into AWS’s authentication services.

AWS Amplify a service that bundles other AWS services to make it simpler to deploy apps. It provides an authentication system that stores login information and sends emails to confirm a user’s email address or to allow them to reset their password. AWS amplify also provides a database.

The ap that I’m building will need to support only the basic CRUD operations (Create, Read, Update and Delete). The role of a server is to tie together services like a database and authentication system. Since AWS Amplify handles these things, it’s possible that I will not need to build my own server.

Normally, a developer would need to know about virtual machines and private networks to get all these features working. While I’d like to become familiar with these technologies, I’m not comfortable using these technologies yet. Even if I was familiar with those topics, I’d probably use AWS Amplify. The app that I’m building is going to do simple CRUD operations on the database as well as sending notifications. To build the system from scratch using the most granular AWS services would be overkill.

Once I decided to use AWS Amplify, I needed somewhere I could mess with the different features. So, I spent a few hours setting up a boilerplate application on my personal AWS account. Fortunately, AWS Amplify has a generous free tier, so I shouldn’t need to pay for the services that I’ll be testing.

To get the app set up, I followed the instructions on the AWS Amplify documentation pages. Along the way, I encountered to challenges. The first was in setting up authentication for the CLI. The second was in creating permissions for the app to use other AWS services.

The AWS Amplify CLI is used to deploy the code from the developer’s computer and to manage some of the services. It took me a whie to get the CLI authenticated with the app that I was setting up. Fortunately, AWS provides clear instructions and I was able to troubleshoot the problem.

In order to set up permissions for my app, I had to create an account for it on my AWS account and assign it permissions. This required me to follow instructions from a completely different section of the AWS documentation before returning to the Amplify docs. Although it was a hastle, it’s necessary for security purposes.

Next week, I’d like to build out a To Do application on this test site. It’s a simple project that will allow me to become familiar with the authentication and database services before bringing it into the main project. By the time I’m done learning about AWS Amplify, I should have the Login and Sign UpP screens designed and ready to be added into the app.

In this post, we are going to leverage AWS Amplify authentication while still building the UI we want. Prerequisites Seeing as this is a post about AWS and AWS Amplify, you should be set up with both of those. Don't have an AWS account yet? You can set one up here. To interact with AWS Amplify you need to install the CLI via npm. $ yarn global add @aws-amplify/cli Setting up our project Before we can show how to build a custom UI using Amplify, we first need a project to work from. Let's use create-react-app to get a React app going. $ npx create-react-app amplify-demo $ cd amplify-demo With our boilerplate project created we can now add the Amplify libraries we are going to need to it. $ yarn add aws-amplify aws-amplify-react Now we need to initialize Amplify and add authentication to our application. From the root of our new amplify-demo application, run the following commands with the following answers to each question. $ amplify init Note: It is recommended to run this command from the root of your app directory ? Enter a name for the project amplify-demo ? Enter a name for the environment prod ? Choose your default editor: Visual Studio Code ? Choose the type of app that you're building: javascript ? What javascript framework are you using react ? Source Directory Path: src ? Distribution Directory Path: build ? Build Command: npm run-script build ? Start Command: npm run-script start $ amplify add auth Using service: Cognito, provided by: awscloudformation The current configured provider is Amazon Cognito. Do you want to use the default authentication and security configuration? Default configuration Warning: you will not be able to edit these selections. How do you want users to be able to sign in? Username Do you want to configure advanced settings? No, I am done. Successfully added resource amplifydemobc1364f5 locally Now that we have the default authentication via Amplify added to our application we can add the default login. To do that go ahead and update your App component located at src/App.js to have the following code. import React from "react"; import logo from "./logo.svg"; import "./App.css"; import { withAuthenticator } from "aws-amplify-react"; import Amplify from "aws-amplify"; import awsconfig from "./aws-exports"; Amplify.configure(awsconfig); function App() { return ( Internal Application behind Login ); } export default withAuthenticator(App); The default Amplify authentication above leverages the higher-order component, withAuthenticator. We should now be able to see that our App component is behind a login. Go ahead and start the app up in development mode by running yarn start. We should see something like below. Customizing The Amplify Authentication UI Now that we have the default authentication wired up it's time to customize it. In the previous blog post we essentially inherited from the internal Amplify components like SignIn. This allowed us to leverage the functions already defined in that component. But, this felt like the wrong abstraction and a bit of a hack for the long term. It was/is a valid way to get something working. But it required knowing quite a few of the implementation details implemented in the parent component. Things like knowing how handleInputChange and _validAuthStates were getting used in SignIn were critical to making the brute force version below work as expected. import React from "react"; import { SignIn } from "aws-amplify-react"; export class CustomSignIn extends SignIn { constructor(props) { super(props); this._validAuthStates = ["signIn", "signedOut", "signedUp"]; } showComponent(theme) { return ( Username .....omitted..... ); } } But in running with this brute force approach for a bit I was able to form up a better way to customize the Amplify authentication UI. The approach, as we are going to see, boils down to three changes. Instead of using the higher-order component, withAuthenticator. We are going to instead use the component instead. This is the component built into the framework that allows for more customization. We are going to change our App component to make use of an AuthWrapper component that we will write. This is the component that can manage the various states of authentication we can be in. Finally, we will write our own CustomSignIn component to have it's own UI and logic. Let's go ahead and dive in with 1️⃣. Below is what our App component is going to look like now. import React from "react"; import { Authenticator } from "aws-amplify-react"; import "./App.css"; import Amplify from "aws-amplify"; import awsconfig from "./aws-exports"; import AuthWrapper from "./AuthWrapper"; Amplify.configure(awsconfig); function App() { return ( ); } export default App; Notice that our App component is now an entry point into our application. It uses the Authenticator component provided by Amplify instead of the higher-order component. We tell that component to hide all the default authentication UI, we are going to create our own. Then inside of that, we make use of a new component we are going to create called AuthWrapper. This new component is going to act as our router for the different authentication pieces we want to have. For this blog post, we are just going to implement the login workflow. But the idea is transferrable to other things like signing up and forgot password. Here is what AuthWrapper ends up looking like. import React, { Component } from "react"; import { InternalApp } from "./InternalApp"; import { CustomSignIn } from "./SignIn"; class AuthWrapper extends Component { constructor(props) { super(props); this.state = { username: "" }; this.updateUsername = this.updateUsername.bind(this); } updateUsername(newUsername) { this.setState({ username: newUsername }); } render() { return ( ); } } export default AuthWrapper; Here we can see that AuthWrapper is a router for two other components. The first one is CustomSignIn, this is the custom login UI we can build-out. The second one is our InternalApp which is the application UI signed in users can access. Note that both components get the authState passed into them. Internally the components can use this state to determine what they should do. Before taking a look at the CustomSignIn component, let's look at InternalApp to see how authState is leveraged. import React, { Component } from "react"; import logo from "../src/logo.svg"; export class InternalApp extends Component { render() { if (this.props.authState === "signedIn") { return ( Internal Application behind Login ); } else { return null; } } } Notice that we are checking that authState === "signedIn" to determine if we should render the application UI. This is a piece of state that is set by the authentication components defined in AuthWrapper. Now let's see what our customized authentication for the login prompt looks like. Here is what CustomSignIn looks like. import React, { Component } from "react"; import { Auth } from "aws-amplify"; export class CustomSignIn extends Component { constructor(props) { super(props); this._validAuthStates = ["signIn", "signedOut", "signedUp"]; this.signIn = this.signIn.bind(this); this.handleInputChange = this.handleInputChange.bind(this); this.handleFormSubmission = this.handleFormSubmission.bind(this); this.state = {}; } handleFormSubmission(evt) { evt.preventDefault(); this.signIn(); } async signIn() { const username = this.inputs.username; const password = this.inputs.password; try { await Auth.signIn(username, password); this.props.onStateChange("signedIn", {}); } catch (err) { if (err.code === "UserNotConfirmedException") { this.props.updateUsername(username); await Auth.resendSignUp(username); this.props.onStateChange("confirmSignUp", {}); } else if (err.code === "NotAuthorizedException") { // The error happens when the incorrect password is provided this.setState({ error: "Login failed." }); } else if (err.code === "UserNotFoundException") { // The error happens when the supplied username/email does not exist in the Cognito user pool this.setState({ error: "Login failed." }); } else { this.setState({ error: "An error has occurred." }); console.error(err); } } } handleInputChange(evt) { this.inputs = this.inputs || {}; const { name, value, type, checked } = evt.target; const check_type = ["radio", "checkbox"].includes(type); this.inputs[name] = check_type ? checked : value; this.inputs["checkedValue"] = check_type ? value : null; this.setState({ error: "" }); } render() { return ( {this._validAuthStates.includes(this.props.authState) && ( Username Password Login )} ); } } What we have defined up above is a React component that is leveraging the Amplify Authentication API. If we take a look at signIn we see many calls to Auth to sign a user in or resend them a confirmation code. We also see that this._validAuthStates still exists. This internal parameter to determines whether we should show this component inside of the render function. This is a lot cleaner and is not relying on knowing the implementation details of base components provided by Amplify. Making this not only more customizable but a lot less error-prone as well. If you take a look at the class names inside of the markup you'll see that this component is also making use of TailwindCSS. Speaking as a non-designer, Tailwind is a lifesaver. It allows you to build out clean looking interfaces with utility first classes. To add Tailwind into your own React project, complete these steps. Run yarn add tailwindcss --dev in the root of your project. Run ./node_modules/.bin/tailwind init tailwind.js to initialize Tailwind in the root of your project. Create a CSS directory mkdir src/css. Add a tailwind source CSS file at src/css/tailwind.src.css with the following inside of it. @tailwind base; @tailwind components; @tailwind utilities; From there we need to update the scripts in our package.json to build our CSS before anything else. "scripts": { "tailwind:css":"tailwind build src/css/tailwind.src.css -c tailwind.js -o src/css/tailwind.css", "start": "yarn tailwind:css && react-scripts start", "build": "yarn tailwind:css && react-scripts build", "test": "yarn tailwind:css && react-scripts test", "eject": "yarn tailwind:css && react-scripts eject" } Then it is a matter of importing our new Tailwind CSS file, import "./css/tailwind.css"; into the root of our app which is App.js. 💥 We can now make use of Tailwind utility classes inside of our React components. Conclusion AWS Amplify is gaining a lot of traction and it's not hard to see why. They are making it easier and easier to integrate apps into the AWS ecosystem. By abstracting away things like authentication, hosting, etc, folks are able to get apps into AWS at lightning speed. But, with abstractions can come guard rails. Frameworks walk a fine line between providing structure and compressing creativity. They need to provide a solid foundation to build upon. But at the same time, they need to provide avenues for customization. As we saw in this post the default Amplify authentication works fine. But we probably don't want exactly that when it comes to deploying our own applications. With a bit of work and extending the framework into our application, we were able to add that customization.

Develop a Secure Video on Demand Application using AWS Amplify

In the revolutionary move, OTT platforms ushered people into an era of on-demand entertainment. With technology evolution, the likes of e-commerce started offering free on-demand services to reduce customer churn. Now users are addicted to the power of ordering their favorite whenever they want instead of waiting for it to stream on grumpy ole cable TV. Are you contemplating opportunities to create one such on-demand platform for your business? Is expansion to the entertainment segment a well-versed part of your growth strategy? If you answered with a yes, brace yourselves, today we are discussing how a Video-on-demand application can be built with AWS Amplify. 

VOD using AWS

is a platform that assists in the instant creation of a streaming platform. Amplify video is designed for applications that are built on the AWS Amplify ecosystem; which offers easier management of back-end infrastructure from the console used for Amplify projects.

What is AWS Amplify?

The prodigy, AWS Amplify is a set of standalone tools, which can be clubbed together or used on their own to build scalable applications and front-end web. The tool is powered by AWS and is of great help to both stack developers and front-end developers. The fact that these tools can be used in combination and separately makes it even more impactful.

Some of the top web framework supported by Amplify includes JavaScript, Angular, Next.js, React and other mobile platforms like iOS, Ionic and Android.

Building a Video On Demand Using AWS

To build an effective video on demand platform using AWS, the pre-required libraries include content management, video processing, content hosting, content delivery, and authorization. To build each of these requisites on your own will take hours and demands a great understanding of varied programming languages.

Amplify VOD simplifies the task by floating a prescriptive streaming architecture into your AWS account with great ease. The agile tool supports the easier creation of video-on-demand streaming platforms.

Let’s go through different steps involved in VOD creation with Amplify

All source files are converted into adaptive bitrate format, which is compatible with the end-user environment. AWS’s AWS Elemental MediaConvert is a unique tool that transcodes all source files and processes them well. Everything in Amplify tool is dependent upon how well Elemental MediaConvert works.

Using a content delivery network improves the delivery speed and ensures a quality experience for end-users. A content management system stores associated metadata and offer control over access to playback. It indexes available assets and serves the audience with all relevant content.

Step 1:

At the very first, we must install Amplify CLI and Amplify video plugin. One can use the npm commands mentioned here.

npm install -g @aws-amplify/cli

npm install amplify-category-video –g

As soon as the installation is done, it is required to create and move into a new director for the Amplify project.

mkdirAmplifyProject

cdAmplifyProject

Once you enter the project’s root directory, Amplify initialization command can be run.

amplifyinit

The above-mentioned code assists in making the local directory & it is where the Amplify project is saved. On implementation an S3 bucket is created for the available AWS account, it is where all the AWS CloudFormation templates are stored. The stored templates are used by Amplify to complete processes like resource deployment. In case AWS CLI is not available, one can complete additional configuration steps as prompted by the tool.

Step 2:

By now the Amplify project is all set and even deployed; the project is connected to the AWS account. You can start adding resources now. Amplify wrap when run creates designs in specified categories, which helps with the creation and effective management of resources in your Video-on-demand using AWS project.

Amplify video plugin can be leveraged as a tool to ensure support for additional categories. With additional video resources and by creating configurations through CLI, one can easily establish a CloudFormation template on the available local machine.

amplify video add

Step 3:

All the prompts will be executed to configure the available video resources. Select the video-on-demand feature and give it a name. On further steps, you are asked to select an encoding template. A set of pre-defined templates are available and you are required to select one of them. The user can also bring in their templates and give their tool a unique touch. At this instant, it is time to respond to prompts such as “Is this a production Environment?”; if you select “yes” here, all your resources will be configured to ensure deployment of a Cloud Front distribution in S3 origin, allowing you to add cache content on Amazon edge network.

Step 4:

By now all resources are built locally and deployed to ensure configuration completion. All the videos now need to be pushed through the configuration to AWS. Amplify Push is one command, which is used to push all videos. Amplify Status is the command used to monitor the state of your available resources.

As soon as the Push command is run, Cloud Formation deploys the available resources to the specified account to configure the Amplify. As soon as, all requisites are created and deployed effectively, the CLI will generate output along with the names of the provided input in the S3 bucket created by Amplify. The bucket is created to processing all videos in the pipeline.

Step 5:

One can use the resources instantly to push configured video resources on Amazon Web Services. When all content processing is completed by MediaConvert, streaming media output will be sent to the output bucket. If you selected a pre-defined template instead of uploading/creating your own. You can locate the .m3u8 file and play HLS content easily. The URL can also be pasted in Safari or other test browsers to run a check. Final Thoughts AWS Amplify has additional capabilities that can help developers achieve incomparable feat within the stipulated period. Spend some time exploring the tools and create effective VOD using AWS. For more guidance on how to amplify your VideoOnDemand service, Feel free to connect with our consultants.

Significance of AWS Amplify

AWS Amplify is the best cloud tool that is preferred by Frontend developers migrating to the cloud. The power of Amplify is exhibited by Nader Dabit, their contribution towards Amplify is very high. The new Admin UI had brought a drastic change at app development, their main objective is to reach more traction. The main objective of using AWS Amplify is to make us to add much more features in a new way easily. The work amplify is very much apt for its processing, it is very descriptive. Amplify empowers frontend a quantum leap in a powerful way. This is because, most of the services are approved by Amplify through the command line. It encourages the process of deployment with a CI/CD pipeline. The possibility of accessing it is really powerful and efficient with the help of App farm. The components of Amplify are CLI, client Libs, UI components, Amplify console – CI/CD and hosting, and AWS device farm. AWS Amplify components are signified into two forms like open-source framework and AWS managed developer services. AWS services are included with multiple things like analytics, AR/VR, data, and storage.

Amplify is always considered the best tool for building applications for web and mobile both front end and backend, the main intention behind it is to integrate them with various AWS tools in a seamless way. There are numerous projects launched this year with AWS Amplify, the number had been increasing every year. Amplify is integrated with other scripts like React, Vue, javascript, iOS, Android, and Flutter. AWS is declared as the best tool that works end-to-end to supercharge apps on the cloud.

AWS Amplify + React Native PubSub

12:06:I’ve been learning React Native by building a Todo app. The backend is maintained by AWS Amplify. Today I’m addng PubSub and calling it programmatically from the API on behalf of the user. The tutorial appears to include a manual CLI step so it’s going to be a learning experience. The below is a real time log of my efforts.

Note: Amplify Auth is best served plain. Aka use Javascript, not Typescript if you want to use the out of the box Auth HOC. It’s written in JS and will fail in a Typescript enabled project.

11:40: Looking at the tutorial here to understand whats happening at a high level: https://docs.amplify.aws/lib/pubsub/getting-started/q/platform/js#aws-iot

11:48: Setting up IoT Core per the instructions: https://console.aws.amazon.com/iot/home?region=us-east-1

Pricing is based on how long a device is connected, which is great:

Connectivity pricing: $0.08 (per million minutes of connection)

For example, in the US East (N. Virginia) region you pay $0.042 per device per year (1 connection * $0.08/1,000,000 minutes of connection * 525,600 minutes/year) for 24/7 connectivity. In order to maintain connectivity, devices may send keep-alive (“Ping”) messages at frequencies ranging from 20 minutes to every 30s, and you do not incur any additional cost for these messages.

11:55: I think you can use the endpoint that’s configured here:

https://console.aws.amazon.com/iot/home?region=us-east-1#/settings

12:06: Setup an “allow all” IoT Policy since I’m just testing this for now.

12:13: Added the policy to my user following these instructions:

Allowing your Amazon Cognito Authenticated Role to access IoT Services

For your Cognito Authenticated Role to be able to interact with AWS IoT it may be necessary to update its permissions, if you haven’t done this before. One way of doing this is to log to your AWS Console, select CloudFormation from the available services. Locate the parent stack of your solution: it is usually named <SERVICE-NAME>-<CREATION_TIMESTAMP>.   Select the Resources tab and tap on AuthRole Physical ID.   The IAM console will be opened in a new tab. Once there, tap on the button Attach Policies, then search AWSIoTDataAccess and AWSIoTConfigAccess, select them and tap on Attach policy. 

I got caught up in something else and never finished this. Sorry :(

Host Your Apps with AWS Amplify Console from the AWS Amplify CLI

[holytheoristtastemaker]

AWS is just too hard to use, and it's not your fault. Today I'm joining to help AWS build for App Developers, and to grow the Amplify Community with people who Learn AWS in Public.

Muck

When AWS officially relaunched in 2006, Jeff Bezos famously pitched it with eight words: "We Build Muck, So You Don’t Have To". And a lot of Muck was built. The 2006 launch included 3 services (S3 for distributed storage, SQS for message queues, EC2 for virtual servers). As of Jan 2020, there were 283. Today, one can get decision fatigue just trying to decide which of the 7 ways to do async message processing in AWS to choose.

The sheer number of AWS services is a punchline, but is also testament to principled customer obsession. With rare exceptions, AWS builds things customers ask for, never deprecates them (even the failures), and only lowers prices. Do this for two decades, and multiply by the growth of the Internet, and it's frankly amazing there aren't more. But the upshot of this is that everyone understands that they can trust AWS never to "move their cheese". Brand AWS is therefore more valuable than any service, because it cannot be copied, it has to be earned. Almost to a fault, AWS prioritizes stability of their Infrastructure as a Service, and in exchange, businesses know that they can give it their most critical workloads.

The tradeoff was beginner friendliness. The AWS Console has improved by leaps and bounds over the years, but it is virtually impossible to make it fit the diverse usecases and experience levels of over one million customers. This was especially true for app developers. AWS was a godsend for backend/IT budgets, taking relative cost of infrastructure from 70% to 30% and solving underutilization by providing virtual servers and elastic capacity. But there was no net reduction in complexity for developers working at the application level. We simply swapped one set of hardware based computing primitives for an on-demand, cheaper (in terms of TCO), unfamiliar, proprietary set of software-defined computing primitives.

In the spectrum of IaaS vs PaaS, App developers just want an opinionated platform with good primitives to build on, rather than having to build their own platform from scratch:

That is where Cloud Distros come in.

Cloud Distros Recap

I've written before about the concept of Cloud Distros, but I'll recap the main points here:

From inception, AWS was conceived as an "Operating System for the Internet" (an analogy echoed by Dave Cutler and Amitabh Srivasta in creating Azure).

Linux operating systems often ship with user friendly customizations, called "distributions" or "distros" for short.

In the same way, there proved to be good (but ultimately not huge) demand for "Platforms as a Service" - with 2007's Heroku as a PaaS for Rails developers, and 2011's Parse and Firebase as a PaaS for Mobile developers atop AWS and Google respectively.

The PaaS idea proved early rather than wrong – the arrival of Kubernetes and AWS Lambda in 2014 presaged the modern crop of cloud startups, from JAMstack CDNs like Netlify and Vercel, to Cloud IDEs like Repl.it and Glitch, to managed clusters like Render and KintoHub, even to moonshot experiments like Darklang. The wild diversity of these approaches to improving App Developer experience, all built atop of AWS/GCP, lead me to christen these "Cloud Distros" rather than the dated PaaS terminology.

Amplify

Amplify is the first truly first-party "Cloud Distro", if you don't count Google-acquired Firebase. This does not make it automatically superior. Far from it! AWS has a lot of non-negotiable requirements to get started (from requiring a credit card upfront to requiring IAM setup for a basic demo). And let's face it, its UI will never win design awards. That just categorically rules it out for many App Devs. In the battle for developer experience, AWS is not the mighty incumbent, it is the underdog.

But Amplify has at least two killer unique attributes that make it compelling to some, and at least worth considering for most:

It scales like AWS scales. All Amplify features are built atop existing AWS services like S3, DynamoDB, and Cognito. If you want to eject to underlying services, you can. The same isn't true of third party Cloud Distros (Begin is a notable exception). This also means you are paying the theoretical low end of costs, since third party Cloud Distros must either charge cost-plus on their users or subsidize with VC money (unsustainable long term). AWS Scale doesn't just mean raw ability to handle throughput, it also means edge cases, security, compliance, monitoring, and advanced functionality have been fully battle tested by others who came before you.

It has a crack team of AWS insiders. I don't know them well yet, but it stands to reason that working on a Cloud Distro from within offers unfair advantages to working on one from without. (It also offers the standard disadvantages of a bigco vs the agility of a startup) If you were to start a company and needed to hire a platform team, you probably couldn't afford this team. If you fit Amplify's target audience, you get this team for free.

Simplification requires opinionation, and on that Amplify makes its biggest bets of all - curating the "best of" other AWS services. Instead of using one of the myriad ways to setup AWS Lambda and configure API Gateway, you can just type amplify add api and the appropriate GraphQL or REST resources are set up for you, with your infrastructure fully described as code. Storage? amplify add storage. Auth? amplify add auth. There's a half dozen more I haven't even got to yet. But all these dedicated services coming together means you don't need to manage servers to do everything you need in an app.

Amplify enables the "fullstack serverless" future. AWS makes the bulk of its money on providing virtual servers today, but from both internal and external metrics, it is clear the future is serverless. A bet on Amplify is a bet on the future of AWS.

Note: there will forever be a place for traditional VPSes and even on-premises data centers - the serverless movement is additive rather than destructive.

For a company famous for having every team operate as separately moving parts, Amplify runs the opposite direction. It normalizes the workflows of its disparate constituents in a single toolchain, from the hosted Amplify Console, to the CLI on your machine, to the Libraries/SDKs that run on your users' devices. And this works the exact same way whether you are working on an iOS, Android, React Native, or JS (React, Vue, Svelte, etc) Web App.

Lastly, it is just abundantly clear that Amplify represents a different kind of AWS than you or I are used to. Unlike most AWS products, Amplify is fully open source. They write integrations for all popular JS frameworks (React, React Native, Angular, Ionic, and Vue) and Swift for iOS and Java/Kotlin for Android. They do support on GitHub and chat on Discord. They even advertise on podcasts you and I listen to, like ShopTalk Show and Ladybug. In short, they're meeting us where we are.

This is, as far as I know, unprecedented in AWS' approach to App Developers. I think it is paying off. Anecdotally, Amplify is growing three times faster than the rest of AWS.

Note: If you'd like to learn more about Amplify, join the free Virtual Amplify Days event from Jun 10-11th to hear customer stories from people who have put every part of Amplify in production. I'll be right there with you taking this all in!

Personal Note

I am joining AWS Mobile today as a Senior Developer Advocate. AWS Mobile houses Amplify, Amplify Console (One stop CI/CD + CDN + DNS), AWS Device Farm (Run tests on real phones), and AppSync (GraphQL Gateway and Realtime/Offline Syncing), and is closely connected to API Gateway (Public API Endpoints) and Amazon Pinpoint (Analytics & Engagement). AppSync is worth a special mention because it is what first put the idea of joining AWS in my head.

A year ago I wrote Optimistic, Offline-first apps using serverless functions and GraphQL sketching out a set of integrated technologies. They would have the net effect of making apps feel a lot faster and more reliable (because optimistic and offline-first), while making it a lot easier to develop this table-stakes experience (because the GraphQL schema lets us establish an eventually consistent client-server contract).

9 months later, the Amplify DataStore was announced at Re:Invent (which addressed most of the things I wanted). I didn't get everything right, but it was clear that I was thinking on the same wavelength as someone at AWS (it turned out to be Richard Threlkeld, but clearly he was supported by others). AWS believed in this wacky idea enough to resource its development over 2 years. I don't think I've ever worked at a place that could do something like that.

I spoke to a variety of companies, large and small, to explore what I wanted to do and figure out my market value. (As an aside: It is TRICKY for developer advocates to put themselves on the market while still employed!) But far and away the smoothest process where I was "on the same page" with everyone was the ~1 month I spent interviewing with AWS. It helped a lot that I'd known my hiring manager, Nader for ~2yrs at this point so there really wasn't a whole lot he didn't already know about me (a huge benefit of Learning in Public btw) nor I him. The final "super day" on-site was challenging and actually had me worried I failed 1-2 of the interviews. But I was pleasantly surprised to hear that I had received unanimous yeses!

Nader is an industry legend and personal inspiration. When I completed my first solo project at my bootcamp, I made a crappy React Native boilerplate that used the best UI Toolkit I could find, React Native Elements. I didn't know it was Nader's. When I applied for my first conference talk, Nader helped review my CFP. When I decided to get better at CSS, Nader encouraged and retweeted me. He is constantly helping out developers, from sharing invaluable advice on being a prosperous consultant, to helping developers find jobs during this crisis, to using his platform to help others get their start. He doesn't just lift others up, he also puts the "heavy lifting" in "undifferentiated heavy lifting"! I am excited he is leading the team, and nervous how our friendship will change now he is my manager.

With this move, I have just gone from bootcamp grad in 2017 to getting hired at a BigCo L6 level in 3 years. My friends say I don't need the validation, but I gotta tell you, it does feel nice.

The coronavirus shutdowns happened almost immediately after I left Netlify, which caused complications in my visa situation (I am not American). I was supposed to start as a US Remote employee in April; instead I'm starting in Singapore today. It's taken a financial toll - I estimate that this coronavirus delay and change in employment situation will cost me about $70k in foregone earnings. This hurts more because I am now the primary earner for my family of 4. I've been writing a book to make up some of that; but all things considered I'm glad to still have a stable job again.

I have never considered myself a "big company" guy. I value autonomy and flexibility, doing the right thing over the done thing. But AWS is not a typical BigCo - it famously runs on "two pizza teams" (not literally true - Amplify is more like 20 pizzas - but still, not huge). I've quoted Bezos since my second ever meetup talk, and have always admired AWS practices from afar, from the 6-pagers right down to the anecdote told in Steve Yegge's Platforms Rant. Time to see this modern colossus from the inside.

The Ultimate Guide To Build React Native App With Expo & Aws Amplify

You might be planning to build a react native app with Expo and AWS Amplify, but do you know why you should go with Expo and AWS Amplify for your react native app development?

AWS Amplify and the CLI enable developers to build, deploy and host your mobile web applications, applications build in react native with Expo empowers in getting new features to your users faster. AWS supports both ways in scaling your application via cloud services and accelerating them to the production.

It supports iOS, Android, Web, and React Native apps adding more that is deep integration with react, Ionic, Angular and Vue.js for web apps.

Amplify is one of the frameworks of AWS which is organized on the features you want to add in your apps such as offline data, multi-factor authentication, analytics, and others. When these features are configured using Amplify CLI the necessary cloud services get provisioned for you.

Expo is a complete tool comes with (SDK) that supports React native application development. You have to write code in Xcode for building an iOS app and Android Studio for Android application. Expo eliminates the dual coding effect by its advanced features and inbuilt libraries that developer can develop both iOS and Android app just coding in JavaScript.

Why You Should Go With Expo?

Ø  Facilitates in setting up the project in an easy way and minutes.

Ø  App sharing made easy by just publishing an app using “expo publish command link” (using the QR code).

Ø  Hassle-free creation of .apk and .ipa in Expo

Ø  Services like Facebook, Google login, push notifications can be easily integrated into your app without any hard work.

Now, this is what you might be seeing something interesting right? Writing on JS and getting developed both iOS and Android at once!

Yes Expo and AWS Amplify does not stop here with their benefits, they have got a lot in them that they provide which has made them super popular in a very short time.

You might be hearing AWS, AWS Amplify, AWS Cloud services, Expo, Expo with React Native, React Native app with Expo, building react native app with Expo and AWS Amplify and much more.

We will get to know below the benefits of building app in expo and aws amplify, which has made many new bees in planning to have their application building react native with expo and AWS Amplify.

1. It allows the developer to test on a real device without having an apple developer account ($99/year). Expo offers a free expo app in play store and app store to run your app within it. It will not give an experience like of same as we get after downloading as you are just in the Expo app but it is cool to test.

2. Expo offers and handles a bunch of configuration steps while deploying your app. configuring by self in Expo gives an awesome experience to beginners who usually do not come from a mobile development background.

3. Expo is a complete tool that comes with SDK which enables it in handling multiple features of an app like camera, maps, analytics, location tracking, accelerometer, etc. yes there is no doubt that most of these features can be implemented using open source packages but having everything at once place has what made Expo Bravo.

4. Updating your app

->Having built an app traditionally in alone react native, to release new versions, the developer has to create a new IPA and APK file and again they have to re-submit to the associated store.

-> Whereas, in Expo JavaScript code, is hosted remotely, thus your app will download any changes and updates made within JavaScript. All you need to do is just re-publish them.

Release of expo version 33 will enable developers making users experience the power of native UI widgets. Expo allows building iOS, Android and Web apps with one code base that saves time and faster delivery.

AWS Amplify is one of the frameworks of AWS that accelerates the development process and vanishes the pain of managing AWS services and strengthening server-less computing and ensuring one back-end support for Android, iOS, and Web clients.

If you are looking to build universal React Native app with AWS Amplify and Expo, then hire react native developers from leading React Native App Development Company who fulfill your requirement within a time-frame.
