In the realm of microservices architecture, Spring Boot stands out for its ability to develop lightweight, independently deployable services. Its compatibility with Spring Cloud offers developers an array of tools for quickly building some of the common patterns in distributed systems (e.g., configuration management, service discovery, circuit breakers). This makes Spring Boot an ideal choice for organizations transitioning to a microservices architecture, as it promotes scalability, resilience, and modularity. Microservices is one important reason why businesses look to migrate to Java 11 and beyond.

Cloud-Native Applications

Spring Boot's design aligns well with cloud-native development principles, facilitating the creation of applications that are resilient, manageable, and observable. By leveraging Spring Boot's actuator module, developers gain insights into application health, metrics, and audit events, which are crucial for Java development services companies maintaining and monitoring applications deployed in cloud environments. Furthermore, Spring Boot's seamless integration with containerization tools like Docker and Kubernetes streamlines the deployment process in cloud environments.

Enterprise Applications

Spring Boot is adept at catering to the complex requirements of enterprise applications. Its seamless integration with Spring Security, Spring Data, and Spring Batch, among others, allows for the development of secure, transactional, and data-intensive applications. Whether it's managing security protocols, handling transactions across multiple databases, or processing large batches of data, Spring Boot provides the necessary infrastructure to develop and maintain robust enterprise applications.

IoT and Big Data Applications

The Internet of Things (IoT) and big data are rapidly growing fields where Spring Boot is finding its footing. By facilitating the development of lightweight, high-performance applications, Spring Boot can serve as the backbone for IoT devices' data collection and processing layers. Additionally, its compatibility with big data processing tools like Apache Kafka and Spring Data makes it suitable for building applications that require real-time data processing and analytics.

Summary

Spring Boot's versatility extends across various domains, making it a valuable tool for developing a wide range of applications—from simple CRUD applications to complex, distributed systems.

Day 000 - bootstrapping

Alright, today is going to be another busy day. I have so much to do, also its snowing?! Wow, that doesn't happen often where I live but it was nice to see, its been ages since I last saw snow, when I was but a whee little boy. Reminds me of a conversation that was had between two characters I like. Let me recreate the scene with my brilliant writing skills.

The beautiful witch looked at the boy and asked, "Why is snow white?", the boy, confused responded that he didn't know to which she answers "The reason its white, is because its forgotten what color its supposed to be". Hours pass by and the two are back together again after spending those hours apart, a conversation has lead to the witch revealing that she doesn't remember anything about herself, the boy while holding her gently says to her, "I still don't know why snow is white, but its beautiful none the less"

Awesome read right? I know I know, keep your panties on, I've some work to do.

The goal of today is to get the team moving forward, we have to finish this app within the next 3 weeks. I'm the technical lead so I have to make sure things go according to plan, I think I finished planning the architecture for the backend, each feature that the app needs will have its own service, each service will be coded using NodeJS (I want to use NestJS but I'm bit too under experienced to even start with that so I'll go with a simple MVC or perhaps the same 3 Tier architecture as NestJS, nothing too complicated). Each service will have its own database (stuck between mysql and postgreSQL but I'll go with mySQL, if I change my mind then I'll migrate) and some services will make use of firestore. Each service only worries about its own data and no sharing, there will be duplication of user data across all services though, I'll think about it later whether its good for security or not.

Communication between the services will be done using RabbitMQ, why? Because its simple and fast, I don't want each service to talk to each other over HTTPS requests, I'd rather make use of RabbitMQ and its free tier.

The frontend, I'll have to supervise the frontend and also do communication with the client on what she thinks because we don't want to disappoint so keeping transparency is a good approach.

I'm planning on deploying all these services using GCP Cloud run, and for the frontend, since its a web app Firebase hosting is good enough. Hopefully there's a good CICD tutorial out there.

I also have to train the AI at some point, what a pain!!! I DON'T EVEN KNOW HOW TO DO THAT!!! Don't judge me because I did an AI class, well I tried my best but I'll have to relearn again.

To summarize what I have to do today:

Finalize the backend system diagram

Set up tasks on project board

Assign mysql databases to each service

Ask our client a question, I don't usually ask so I'll make sure its a useful question

Good luck to me, let's do our best!!

Hi!! I'm the anon who sent @/jv the question about how tumblr is handling boops, thanks for answering it in detail i really appreciate it!!! I understand some of it but there's room to learn and I'll look forward to that.

can I ask a follow up question, i don't know if this makes sense but is it possible to use something like k8s containers instead of lots of servers for this purpose?

Hi! Thanks for reaching out.

Yeah my bad, I didn't know what your technical skill level is, so I wasn't writing it in a very approachable level.

The main takeaway is, high scalability has to happen on all levels - feature design, software architecture, networking, hardware, software, and software management.

K8s (an open source software project called Kubernetes, for the normal people) is on the "software management" category. It's like what MS Outlook or Google Calendar is to meetings. It doesn't do the meetings for you, it doesn't give you more time or more meeting rooms, but it gives you a way to say who goes where, and see which rooms are booked.

While I cannot say for Tumblr, I think I've heard they use Kubernetes at least in some parts of the stack, I can't speak for them. I can speak for myself tho! Been using K8s in production since 2015.

Once you want to run more than "1 redis 1 database 1 app" kind of situation, you will likely benefit from using K8s. Whether you have just a small raspberry pi somewhere, a rented consumer-grade server from Hetzner, or a few thousand machines, K8s can likely help you manage software.

So in short: yes, K8s can help with scalability, as long as the overall architecture doesn't fundamentally oppose getting scaled. Meaning, if you would have a central database for a hundred million of your users, and it becomes a bottleneck, then no amount of microservices serving boops, running with or without K8s, will not remove that bottleneck.

"Containers", often called Docker containers (although by default K8s has long stopped using Docker as a runtime, and Docker is mostly just something devs use to build containers) are basically a zip file with some info about what to run on start. K8s cannot be used without containers.

You can run containers without K8s, which might make sense if you're very hardware resource restricted (i.e. a single Raspberry Pi, developer laptop, or single-purpose home server). If you don't need to manage or monitor the cluster (i.e. the set of apps/servers that you run), then you don't benefit a lot from K8s.

Kubernetes is handy because you can basically do this (IRL you'd use some CI/CD pipeline and not do this from console, but conceptually this happens) -

kubectl create -f /stuff/boop_service.yaml kubectl create -f /stuff/boop_ingress.yaml kubectl create -f /stuff/boop_configmap.yaml kubectl create -f /stuff/boop_deploy.yaml

(service is a http endpoint, ingress is how the service will be available from outside of the cluster, configmap is just a bunch of settings and config files, and deploy is the thing that manages the actual stuff running)

At this hypothetical point, Tumblr stuff deploys, updates and tests the boop service before 1st April, generally having some one-click deploy feature in Jenkins or Spinnaker or similar. After it's tested and it's time to bring in the feature to everyone, they'd run

kubectl scale deploy boop --replicas=999

and wait until it downloads and runs the boop server on however many servers. Then they either deploy frontend to use this, or more likely, the frontend code is already live, and just displays boop features based on server time, or some server settings endpoint which just says "ok you can show boop now".

And then when it's over and they disable it in frontend, just again kubectl scale .. --replicas=10 to mop up whichever people haven't refreshed frontend and still are trying to spam boops.

This example, of course, assumes that "boop" is a completely separate software package/server, which is about 85/15% chance that it isn't, and more likely it's just one endpoint that they added to their existing server code, and is already running on hundreds of servers. IDK how Tumblr manages the server side code at all, so it's all just guesses.

Hope this was somewhat interesting and maybe even helpful! Feel free to send more asks.
