Amazon Web Services provides many companies with the service to deploy their Kubernetes apps. Container apps are very widely used as a virtualization method but with the benefit of not having to run a full virtual machine, essentially being able to virtualize only the application.
The name of the service is: Amazon Elastic Kubernetes Service. And its clients include Intel, Snapchat, Intuit, GoDaddy among others. These companies choose Amazon EKS for reliability and scalability opportunities.
As it´s not the only Amazon Web Service that helps Kubernetes apps, the environment is prepared to deploy your app in the best way possible. You can choose to run your app in serverless computers using AWS Fargate.
Is EKS backed by other AWS Services?
AWS Fargate is not the only service that enriches the app deployment. EKS is integrated with Amazon CloudWatch, AWS Identity, Amazon Virtual Private Cloud, and AWS App Mesh. Each service contributes to the improvement of the deployment of the Kubernetes app in its current version.
It is always positively considered to consider failure, but in this case, it is almost guaranteed that failure will not be an option. With so much infrastructure to hold a single application, you can rest assured that it will run well.
If you are currently running your application in the Kubernetes environment, the migration is easy and doesn’t require to refactor the code. AWS prepared the service by adapting to Kubernetes.
How does It work?
The process comes in five steps. Amazon provides an EKS cluster. Deploy a serverless container in Amazon Fargate. Deploy worker nodes for your cluster in Amazon EC2. Connect them to EKS and you are ready to run Kubernetes apps inside the EKS environment.
The services prioritize security. Kubernetes clusters are isolated from each other. The usage of a virtual private cloud makes the clusters separate from other customers. Essentially is like having a cloud for yourself to run and deploy your applications. The Amazon VPC works like a VPN but instead of running as a network, it provides its cloud service with the ultimate layer of security.
With the success of AWS clients with EKS, Amazon introduces a complete CDK for Kubernetes. They decided to put their time and effort to deliver a full development kit for developers. Most users use EKS to train machine learning models and as a standard for the delivery of innovation through data centers and cloud computing. Their specifications and details come to top-notch when it comes to implementing operational infrastructure.
Kubernetes apps, are human-readable static YAML data files that developers write manually. The project is Open-Source and there is a big community that supports developers to understand and improve the way apps are developed. The larger a team is working on any software project, the more united they have to become. Either by the use of project management, or by connecting all their specific departments in one place. The same happens with Kubernetes, as the files become bigger, they are harder to manage.
There is one big problem with YAML, it does not express logic and reusable code. For it, there are separate extensions, and tools, such as Kustomizer, Jsonnet, Jkcfg, Kubegen, which solve this gap in different ways. AWS cloud development kit (AWS CDK) solves the problem entirely, helping all the Kubernetes developers develop their apps in one place.
CDK Development followed by EKS success
The CDK lets you define Kubernetes applications using familiar programming languages. You can use python to then be translated into Kubernetes YAML. CDK also lets users import API objects, to extend object-oriented programming functions into Kubernetes apps.
As we can see, AWS not only helps you run and develop your applications in one place, but in even better form than by developing them in the native Kubernetes ecosystem. They have improved the standard of the developers of Kubernetes.
If you are interested in developing with this technology, be sure to publish your development to the code libraries, to then be referenced to any application. It is really important to share knowledge, as we can expect, the future of programming is open-source.
In AWS EKS, the pricing is $0,10 per hour per cluster created. Following Amazon´s policy of “you only pay for what you use”, users can see better pricing details by checking their usage needs on Amazon EC2 cost calculator.
In conclusion, Amazon has put Kubernetes one step forward in its development capabilities by offering a full service (EKS) and a CDK based on the success of the service. The CDK improves the native capabilities of Kubernetes, integrating object-oriented programming features and allowing the development of logic components to be integrated without external tools. The biggest company names use the service and are happy customers. Before migrating your Kubernetes Development, consider the benefits, and well, the rest will fall into place.
