AEM aaCS aka Adobe Experience Manager as a Cloud Service

As the industry standard for digital experience management, Adobe Experience Manager is now being improved upon. Finally, Adobe is transferring Adobe Experience Manager (AEM), its final on-premises product, to the cloud.

AEM aaCS is a modern, cloud-native application that accelerates the delivery of omnichannel application.

The AEM Cloud Service introduces the next generation of the AEM product line, moving away from versioned releases like AEM 6.4, AEM 6.5, etc. to a continuous release with less versioning called "AEM as a Cloud Service."

AEM Cloud Service adopts all benefits of modern cloud based services:

Availability

The ability for all services to be always on, ensuring that our clients do not suffer any downtime, is one of the major advantages of switching to AEM Cloud Service. In the past, there was a requirement to regularly halt the service for various maintenance operations, including updates, patches, upgrades, and certain standard maintenance activities, notably on the author side.

Scalability

The AEM Cloud Service's instances are all generated with the same default size. AEM Cloud Service is built on an orchestration engine (Kubernetes) that dynamically scales up and down in accordance with the demands of our clients without requiring their involvement. both horizontally and vertically. Based on, scaling can be done manually or automatically.

Updated Code Base

This might be the most beneficial and much anticipated function that AEM Cloud Service offers to consumers. With the AEM Cloud Service, Adobe will handle upgrading all instances to the most recent code base. No downtime will be experienced throughout the update process.

Self Evolving

Continually improving and learning from the projects our clients deploy, AEM Cloud Service. We regularly examine and validate content, code, and settings against best practices to help our clients understand how to accomplish their business objectives. AEM cloud solution components that include health checks enable them to self-heal.

AEM as a Cloud Service: Changes and Challenges

When you begin your work, you will notice a lot of changes in the aem cloud jar. Here are a few significant changes that might have an effect on how we now operate with aem:-

1)The significant exhibition bottleneck that the greater part of huge endeavor DAM clients are confronting is mass transferring of resource on creator example and afterward DAM Update work process debase execution of entire creator occurrence. To determine this AEM Cloud administration brings Resource Microservices for serverless resource handling controlled by Adobe I/O. Presently when creator transfers any resource it will go straightforwardly to cloud paired capacity then adobe I/O is set off which will deal with additional handling by utilizing versions and different properties that has been designed.

2)Due to Adobe's complete management of AEM cloud service, developers and operations personnel may not be able to directly access logs. As of right now, the only way I know of to request access, error, dispatcher, and other logs will be via a cloud manager download link.

3)The only way for AEM Leads to deploy is through cloud manager, which is subject to stringent CI/CD pipeline quality checks. At this point, you should concentrate on test-driven development with greater than 50% test coverage. Go to https://docs.adobe.com/content/help/en/experience-manager-cloud-manager/using/how-to-use/understand-your-test-results.html for additional information.

4)AEM as a cloud service does not currently support AEM screens or AEM Adaptive forms.

5)Continuous updates will be pushed to the cloud-based AEM Base line image to support version-less solutions. Consequently, any Asset UI console or libs granite customizations: Up until AEM 6.5, the internal node, which could be used as a workaround to meet customer requirements, is no longer possible because it will be replaced with each base line image update.

6)Local sonar cannot use the code quality rules that are available in cloud manager before pushing to git. which I believe will result in increased development time and git commits. Once the development code is pushed to the git repository and the build is started, cloud manager will run sonar checks and tell you what's wrong. As a precaution, I recommend that you do not have any problems with the default rules in your local environment and that you continue to update the rules whenever you encounter them while pushing the code to cloud git.

AEM Cloud Service Does Not Support These Features

1.AEM Sites Commerce add-on 2.Screens add-on 3.Networks add-on 4.AEM Structures 5.Admittance to Exemplary UI. 6.Page Editor is in Developer Mode. 7./apps or /libs are ready-only in dev/stage/prod environment – changes need to come in via CI/CD pipeline that builds the code from the GIT repo. 8.OSGI bundles and settings: the dev, stage, and production environments do not support the web console.

If you encounter any difficulties or observe any issue , please let me know. It will be useful for AEM people group.

Best Practices for Deploying Kubernetes in Production Environments

Kubernetes has emerged as the go-to solution for container orchestration, enabling organizations to efficiently manage, scale, and deploy containerized applications. Whether you're deploying Kubernetes in the cloud or on-premises, following best practices is essential to ensuring a smooth, scalable, and secure production environment. In this blog, we'll explore the key best practices for deploying Kubernetes in production and how these practices can help businesses optimize their infrastructure.

We'll also touch upon the "Docker Swarm vs Kubernetes" debate to highlight why Kubernetes is often the preferred choice for large-scale production environments.

1. Plan for Scalability from Day One

One of the main reasons companies adopt Kubernetes is its ability to scale applications seamlessly. To take full advantage of this feature, it’s important to design your architecture with scalability in mind from the beginning.

Cluster Size: Initially, it might be tempting to start with a smaller cluster. However, it’s a good idea to think ahead and choose an appropriate cluster size that can handle both current and future workloads. Use node autoscaling to dynamically adjust your cluster size based on demand.

Resource Requests and Limits: Properly configure resource requests and limits for CPU and memory for each pod. This ensures that your application can handle increased workloads without overwhelming the cluster or causing bottlenecks.

By following these scalability practices, you can ensure your Kubernetes environment is built to grow as your business and application demands increase.

2. Use Namespaces to Organize Resources

Namespaces are essential for organizing resources in a Kubernetes cluster. They allow you to logically divide your cluster based on environments (e.g., development, staging, and production) or teams.

Separation of Concerns: Using namespaces, you can separate concerns and prevent different teams or environments from affecting each other.

Resource Quotas: Kubernetes allows you to set resource quotas per namespace, ensuring no single namespace consumes all available resources. This is particularly helpful when managing multiple teams or projects on the same cluster.

Network Policies: Network policies can be configured per namespace to ensure secure communication between different services within a namespace and restrict unwanted access from other namespaces.

Implementing namespaces effectively will help maintain order within your Kubernetes cluster, making it easier to manage and scale.

3. Automate Everything with CI/CD Pipelines

Continuous Integration and Continuous Deployment (CI/CD) pipelines are crucial for deploying updates efficiently and consistently. Automation not only reduces the chance of human error but also speeds up deployment processes.

Integration with Kubernetes: Your CI/CD pipeline should be able to automate Kubernetes deployments, ensuring that any changes made to the application or infrastructure are automatically reflected in the cluster.

Helm Charts: Use Helm charts to package, manage, and deploy Kubernetes applications. Helm makes it easier to automate deployments by allowing you to define, version, and share application configurations.

Rollbacks: Ensure that your CI/CD pipeline has a rollback mechanism in place. If an update fails or introduces issues, a rollback feature can quickly revert your environment to a previous stable version.

Automation ensures that your Kubernetes environment is always up-to-date and that any new code is deployed with minimal manual intervention.

4. Prioritize Security

Security in a Kubernetes production environment should be a top priority. Kubernetes has multiple layers of security that need to be configured correctly to avoid vulnerabilities.

Role-Based Access Control (RBAC): RBAC is essential for limiting what users and service accounts can do within your cluster. Ensure that you’re using the principle of least privilege by granting users the minimal permissions they need to do their job.

Secrets Management: Use Kubernetes Secrets to store sensitive information, such as passwords and API keys, securely. Ensure that your Secrets are encrypted at rest.

Pod Security Policies (PSPs): Enable Pod Security Policies to control the security settings of your pods. This can help prevent privilege escalation, limit the capabilities of your containers, and define safe deployment practices.

Network Security: Use network policies to restrict traffic between pods. By default, all pods in Kubernetes can communicate with each other, but you can create rules that control which pods are allowed to communicate and which aren’t.

Implementing these security measures from the start ensures that your Kubernetes cluster is resilient against potential threats and attacks.

5. Optimize Resource Usage

Efficient resource utilization is crucial to running Kubernetes cost-effectively, especially in a production environment.

Horizontal Pod Autoscaling (HPA): Use HPA to automatically adjust the number of pods in a deployment based on CPU utilization or other custom metrics. This allows your application to handle varying loads without manually scaling resources.

Vertical Pod Autoscaling (VPA): While HPA scales the number of pods, VPA adjusts the CPU and memory limits for individual pods. This ensures that your application is always running with optimal resources based on its current workload.

Cluster Autoscaler: Enable Cluster Autoscaler to automatically add or remove nodes from the cluster depending on the resource requirements of your pods. This helps in managing costs by ensuring that you’re not running unnecessary nodes during low traffic periods.

Optimizing resource usage ensures that your infrastructure is cost-effective while still being able to handle large spikes in traffic.

6. Monitor and Log Everything

In a production environment, visibility into what’s happening in your Kubernetes cluster is vital. Proper monitoring and logging ensure that you can detect, troubleshoot, and resolve issues before they become critical.

Monitoring Tools: Use tools like Prometheus and Grafana for monitoring your Kubernetes cluster. These tools can track performance metrics such as CPU, memory usage, and the health of your applications.

Logging Tools: Implement centralized logging using tools like Elasticsearch, Fluentd, and Kibana (EFK stack). Centralized logging helps you troubleshoot issues across multiple services and components.

Alerting: Configure alerting systems to notify your team when certain thresholds are breached or when a service fails. Early detection allows you to address problems before they affect your users.

With robust monitoring and logging in place, you can quickly detect and resolve issues, ensuring that your applications remain available and performant.

7. Use Blue-Green or Canary Deployments

When deploying new versions of your application, it’s important to minimize the risk of downtime or failed releases. Two popular strategies for achieving this in Kubernetes are Blue-Green deployments and Canary deployments.

Blue-Green Deployments: This strategy involves running two identical environments: one for production (blue) and one for testing (green). Once the new version of the application is tested in the green environment, traffic is switched over to it, ensuring zero downtime.

Canary Deployments: In a Canary deployment, a small percentage of traffic is routed to the new version of the application while the rest continues to use the previous version. If the new version works as expected, more traffic is gradually routed to it.

Both strategies reduce the risk of introducing issues into production by allowing you to test new versions before fully rolling them out.

Docker Swarm vs Kubernetes: Why Kubernetes is the Preferred Choice for Production

While Docker Swarm provides a simpler setup and is easier for smaller deployments, Kubernetes has become the preferred solution for large-scale production environments. Kubernetes offers greater flexibility, better scalability, and a more robust ecosystem of tools and plugins. Features like horizontal autoscaling, advanced networking, and better handling of stateful applications give Kubernetes a significant advantage over Docker Swarm.

By following these best practices, businesses can ensure that their Kubernetes production environments are secure, scalable, and efficient. Whether you're just starting with Kubernetes or looking to optimize your existing setup, the right approach will save time, reduce costs, and improve the overall performance of your applications.

Trantor, with its extensive experience in cloud-native technologies and container orchestration, helps businesses deploy, scale, and manage Kubernetes clusters, ensuring a smooth and optimized production environment.

Introduction to Kubernetes

Kubernetes, often abbreviated as K8s, is an open-source platform designed to automate deploying, scaling, and operating application containers. Originally developed by Google, it is now maintained by the Cloud Native Computing Foundation (CNCF). Kubernetes has become the de facto standard for container orchestration, offering a robust framework for managing microservices architectures in production environments.

In today's rapidly evolving tech landscape, Kubernetes plays a crucial role in modern application development. It provides the necessary tools and capabilities to handle complex, distributed systems reliably and efficiently. From scaling applications seamlessly to ensuring high availability, Kubernetes is indispensable for organizations aiming to achieve agility and resilience in their software deployments.

History and Evolution of Kubernetes

The origins of Kubernetes trace back to Google's internal system called Borg, which managed large-scale containerized applications. Drawing from years of experience and lessons learned with Borg, Google introduced Kubernetes to the public in 2014. Since then, it has undergone significant development and community contributions, evolving into a comprehensive and flexible orchestration platform.

Some key milestones in the evolution of Kubernetes include its donation to the CNCF in 2015, the release of version 1.0 the same year, and the subsequent releases that brought enhanced features and stability. Today, Kubernetes is supported by a vast ecosystem of tools, extensions, and integrations, making it a cornerstone of cloud-native computing.

Key Concepts and Components

Nodes and Clusters

A Kubernetes cluster is a set of nodes, where each node can be either a physical or virtual machine. There are two types of nodes: master nodes, which manage the cluster, and worker nodes, which run the containerized applications.

Pods and Containers

At the core of Kubernetes is the concept of a Pod, the smallest deployable unit that can contain one or more containers. Pods encapsulate an application’s container(s), storage resources, a unique network IP, and options on how the container(s) should run.

Deployments and ReplicaSets

Deployments are used to manage and scale sets of identical Pods. A Deployment ensures that a specified number of Pods are running at all times, providing declarative updates to applications. ReplicaSets are a subset of Deployments that maintain a stable set of replica Pods running at any given time.

Services and Networking

Services in Kubernetes provide a stable IP address and DNS name to a set of Pods, facilitating seamless networking. They abstract the complexity of networking by enabling communication between Pods and other services without needing to manage individual Pod IP addresses.

Kubernetes Architecture

Master and Worker Nodes

The Kubernetes architecture is based on a master-worker model. The master node controls and manages the cluster, while the worker nodes run the applications. The master node’s key components include the API server, scheduler, and controller manager, which together manage the cluster’s state and lifecycle.

Control Plane Components

The control plane, primarily hosted on the master node, comprises several critical components:

API Server: The front-end for the Kubernetes control plane, handling all API requests for managing cluster resources.

etcd: A distributed key-value store that holds the cluster’s state data.

Scheduler: Assigns workloads to worker nodes based on resource availability and other constraints.

Controller Manager: Runs various controllers to regulate the state of the cluster, such as node controllers, replication controllers, and more.

Node Components

Each worker node hosts several essential components:

kubelet: An agent that runs on each node, ensuring containers are running in Pods.

kube-proxy: Maintains network rules on nodes, enabling communication to and from Pods.

Container Runtime: Software responsible for running the containers, such as Docker or containerd.

This involves identifying underutilized resources, automating resource provisioning, and implementing efficient monitoring and alerting systems.

Solutions for Scaling Cloud Infrastructure for CTOs: 

Horizontal Scaling: One of the most common approaches to scaling cloud infrastructure is horizontal scaling. Businesses can achieve better performance and handle increased traffic by adding more instances or nodes to distribute the workload. This approach often requires load balancing and auto-scaling mechanisms to allocate resources based on demand dynamically.

Utilize Containerization and Orchestration: Containerization technologies like Docker and container orchestration platforms like Kubernetes can simplify scaling. Containers provide lightweight, isolated environments for applications, making deploying and scaling them easier. Orchestration tools enable CTOs to manage containers at scale, automating deployment, scaling, and management processes.

Implement Serverless Architecture: Serverless computing abstracts the infrastructure layer, allowing CTOs to focus on writing and deploying code without managing underlying servers. Serverless architectures, like AWS Lambda, scale automatically based on the incoming workload, minimizing operational complexities. This approach can significantly simplify scaling infrastructure for certain types of workloads.

DevOps and Automation: Implementing DevOps practices and leveraging automation tools can streamline scaling. Automation helps ensure consistency, reduces human error and accelerates the scaling process. Continuous integration and delivery (CI/CD) pipelines enable faster and more reliable deployments, while infrastructure-as-code (IaC) tools like AWS CloudFormation or Terraform provide a declarative approach to provisioning and managing infrastructure resources.

Principal Advantages Of The Storage Pool + Hyperdisk On GKE

Do you want to pay less for storing GKE blocks? Storage Pool for Hyperdisks may assist Whether you’re managing GKE clusters, conventional virtual machines, or both, it’s critical to automate as many of your operational chores as you can in an economical way.

Pool Storage

Hyperdisk Storage Pool are a pre-purchased collection of capacity, throughput, and IOPS that you can then supply to your applications as required. Hyperdisk is a next-generation network connected block storage solution. Hyperdisk block storage disks allow you to optimize operations and costs by sharing capacity and performance across all the disks in a pool when you put them in storage pools. Hyperdisk Storage Pools may reduce your Total Cost of Ownership (TCO) associated with storage by up to 30–50%, and as of Google Kubernetes Engine (GKE) 1.29.2, they can be used on GKE!

Thin provisioning in Storage Pool makes this feasible by enabling you to use the capacity that is allocated inside the pool only when data is written, not when pool disks are provided. Rather of provisioning each disk for peak demand regardless of whether it ever experiences that load, capacity, IOPS, and throughput are bought at the pool level and used by the disks in the pool on an as-needed basis, enabling you to share resources as needed:

Why is Hyperdisk used?

Hyperdisk, the next generation of Google Cloud persistent block storage, is different from conventional persistent disks in that it permits control of throughput and IOPS in addition to capacity. Additionally, even after the disks are first configured, you may adjust their performance to match your specific application requirements, eliminating extra capacity and enabling cost savings.Image Credit Google Cloud

How about Storage Pool?

In contrast, storage pools allow you to share a thinly-provisioned capacity pool across many Hyperdisks in a single project that are all located in the same zone, or “Advanced Capacity” Storage Pool. Rather to using storage capacity that is provided, you buy the capacity up front and just use it for data that is written. Throughput and IOPS may be adjusted in a similar manner in a storage pool referred to as “Advanced Capacity & Advanced Performance.”

Combining Hyperdisk with Storage Pools reduces the total cost of ownership (TCO) for block storage by shifting management responsibilities from the disk level to the pool level, where all disks within the pool absorb changes. A Storage Pool is a zonal resource with a minimum capacity of 10TB and requires a hyperdisk of the same kind (throughput or balanced).

Hyperdisk

Storage Pool + Hyperdisk on GKE

Hyperdisk Balanced boot disks and Hyperdisk Balanced or Hyperdisk Throughput attached disks may now be created on GKE nodes within Storage Pool, as of GKE 1.29.2.

Let’s imagine you want to be able to adjust the performance to suit your workload for a demanding stateful application that is executing in us-central-a. You decide to use Hyperdisk Balanced for the workload’s block storage. You employ a Hyperdisk Balanced Advanced Capacity, Advanced Performance Storage Pools in place of trying to right-size each disk in your application. The capacity and performance are paid for beforehand.

Pool performance is used up when the disks in the storage pool notice an increase in IOPS or throughput, while pool capacity is only used up when your application writes data to the disks. Prior to creating the Hyperdisks inside the Storage Pool(s) must be created.

Google Cloud Hyperdisk

Use the following gcloud command to establish an Advanced Capacity, Advanced Performance StoragePools:gcloud compute storage-pools create pool-us-central1-a --provisioned-capacity=10tb --storage-pool-type=hyperdisk-balanced --zone=us-central1-a --project=my-project-id --capacity-provisioning-type=advanced --performance-provisioning-type=advanced --provisioned-iops=10000 --provisioned-throughput=1024

The Pantheon UI may also be used to construct Storage Pools.

You may also provide your node boot disks in the storage pool if your GKE nodes are utilizing Hyperdisk Balanced as their boot drives. This may be set up at cluster or node-pool construction, as well as during node-pool updates. You may use the Pantheon UI or the following gcloud command to provide your Hyperdisk Balanced node boot drives in your Storage Pool upon cluster setup. Keep in mind that your Storage Pool has to be established in the same zone as your cluster and that the machine type of the nodes needs to support Hyperdisk Balanced.

You must use the storage-pools StorageClass argument to define your Storage Pool in order to deploy the Hyperdisk Balanced disks that your stateful application uses in it. The Hyperdisk Balanced volume that your application will utilize is then provisioned using a Persistent Volume Claim (PVC) that uses the StorageClass.

The provisioned-throughput-on-create and provisioned-iops-on-create parameters are optional and may be specified by the StorageClass. The volume will default to 3000 IOPS and 140Mi throughput if provisioned-throughput-on-create and provisioned-iops-on-create are left empty. Any IOPS or Throughput from the StoragePool will only be used by IOPS and Throughput values that exceed these preset levels.

Google Hyperdisk

The allowed IOPS and throughput figures vary based on the size of the drive.

Only 40 MiB of throughput and 1000 IOPS will be used by volumes allocated with this StorageClass from the Storage Pools.

Next, create a PVC with a reference to the StorageClass storage-pools-sc.

The pooling-storage-sc When a Pod utilizing the PVC is formed, Storage Class’s Volume Binding Mode: Wait For First Consumer is used, delaying the binding and provisioning of a Persistent Volume.

Finally, utilize the aforementioned PVC to include these Hyperdisk Volumes into your Stateful application. It is necessary to schedule your application to a node pool that has computers capable of attaching Hyperdisk Balanced.

NodeSelectors are used in the Postgres deployment to make sure that pods are scheduled to nodes that allow connecting Hyperdisk Balanced, or C3 machine types.

You ought now be able to see that your storage pools has your Hyperdisk Balanced volume deployed.

Next actions

For your stateful applications, you may optimize storage cost reductions and efficiency by using a Storage Pools + Hyperdisk approach for GKE.
