It aims to shorten the systems development life cycle and provide continuous delivery with high software quality. EKS plays a crucial role in the DevOps ecosystem by providing a platform for automating deployment, scaling, and operations of application containers across clusters of hosts. This glossary entry will explore the relationship between EKS and DevOps, and how they work together to improve business efficiency.
Definition of EKS
EKS, or Amazon Elastic Kubernetes Service, is a cloud-based service provided by Amazon Web Services (AWS) that allows users to run Kubernetes, an open-source system for automating deployment, scaling, and management of containerized applications, without the need to manage the underlying Kubernetes infrastructure. EKS manages the Kubernetes control plane for the user, ensuring high availability, reliability, and scalability.
It's important to note that EKS is not a standalone service, but rather a part of the larger AWS ecosystem. This means it can seamlessly integrate with other AWS services like Amazon RDS, Amazon S3, and AWS Lambda, providing users with a comprehensive and versatile platform for managing their applications.
Understanding Kubernetes
Kubernetes, often abbreviated as K8s, is an open-source platform designed to automate deploying, scaling, and operating application containers. It groups containers that make up an application into logical units for easy management and discovery. Kubernetes was originally designed by Google and is now maintained by the Cloud Native Computing Foundation.
Kubernetes provides a framework to run distributed systems resiliently. It takes care of scaling and failover for your applications, provides deployment patterns, and more. For example, Kubernetes can easily manage a canary deployment for your system.
Role of EKS in DevOps
In the world of DevOps, EKS plays a critical role by providing a platform for automating deployment, scaling, and operations of application containers across clusters of hosts. This automation not only reduces the burden on IT teams but also significantly speeds up the development and deployment process, leading to faster time-to-market and improved business efficiency.
EKS also plays a crucial role in implementing the principles of 'Infrastructure as Code' (IaC), a key DevOps practice. With IaC, infrastructure management becomes as flexible and version-controlled as software development, allowing for rapid, repeatable, and reliable provisioning and changes to infrastructure.
Continuous Integration and Continuous Deployment (CI/CD)
One of the key principles of DevOps is Continuous Integration and Continuous Deployment (CI/CD), which aims to automate the process of software delivery. EKS supports this by providing a robust platform for deploying, scaling, and managing containerized applications.
With EKS, developers can push code changes to a version control repository, and these changes can be automatically built, tested, and deployed to production. This not only speeds up the development process but also ensures that any issues are identified and fixed quickly, leading to higher software quality.
Microservices Architecture
EKS also supports the microservices architecture, a design approach in which a single application is built as a suite of small services, each running in its own process and communicating with lightweight mechanisms. This architecture is a key enabler of DevOps as it allows for rapid, independent development and deployment of individual components of an application.
With EKS, each microservice can be deployed, scaled, and managed independently, providing a high degree of flexibility and resilience. This not only improves the reliability of applications but also allows for faster innovation and quicker response to market demands.
History of EKS
Amazon Elastic Kubernetes Service (EKS) was launched by AWS in June 2018 as a fully managed service that makes it easy for users to run Kubernetes on AWS without needing to install and operate their own Kubernetes clusters. The launch of EKS was a response to the growing popularity of Kubernetes as a platform for managing containerized applications.
Since its launch, EKS has seen rapid adoption by businesses of all sizes, from startups to large enterprises. Its scalability, reliability, and seamless integration with other AWS services have made it a popular choice for managing containerized applications.
Integration with AWS Services
One of the key features of EKS is its seamless integration with other AWS services. This allows users to leverage the full power of the AWS ecosystem to manage their applications. For example, EKS can integrate with Amazon RDS to manage databases, AWS Lambda for serverless computing, and Amazon S3 for storage.
This integration not only provides users with a comprehensive platform for managing their applications but also allows them to take advantage of the scalability, reliability, and security of AWS.
Use Cases of EKS
EKS has a wide range of use cases, thanks to its scalability, reliability, and versatility. It can be used to manage microservices, batch processing, machine learning applications, and more. In this section, we will explore some of the most common use cases of EKS.
One of the most common use cases of EKS is managing microservices. Microservices architecture is a design approach in which a single application is built as a suite of small services, each running in its own process and communicating with lightweight mechanisms. EKS provides a robust platform for deploying, scaling, and managing these microservices, providing a high degree of flexibility and resilience.
Batch Processing
EKS is also commonly used for batch processing, a method of running high-volume, repetitive data jobs. The batch jobs are collected and processed on a schedule or when resources become available. With EKS, these batch jobs can be easily scaled and managed, ensuring efficient use of resources and quick processing times.
For example, a financial institution might use EKS to run end-of-day processing jobs, where transactions made throughout the day are processed in a single, large batch. EKS would allow this institution to scale up resources to handle the large volume of transactions, and then scale down resources when the processing is complete, saving on costs.
Machine Learning
EKS is also used for machine learning applications. Machine learning involves training models using large datasets, a process that requires significant computational resources. EKS allows these resources to be easily scaled up and down as needed, making it an efficient platform for machine learning.
For example, a healthcare company might use EKS to train a machine learning model to predict patient outcomes based on a variety of factors. EKS would allow the company to easily scale up resources during the training process, and then scale down resources once the model is trained, saving on costs.
Examples of EKS in Action
Many businesses across various industries have successfully implemented EKS to manage their applications and services. In this section, we will look at a few specific examples of how EKS has been used in real-world scenarios.
One example is GoDaddy, the world's largest domain name registrar. GoDaddy uses EKS to manage its Kubernetes workloads, allowing it to scale its services to handle the large volume of traffic it receives. By using EKS, GoDaddy has been able to reduce its operational overhead and improve its service reliability.
Intuit Case Study
Intuit, a financial software company, is another example of a business that has successfully implemented EKS. Intuit uses EKS to run its TurboTax platform, which is used by millions of people to file their taxes. By using EKS, Intuit has been able to scale its services to handle the large volume of traffic it receives during tax season, ensuring a smooth experience for its users.
Intuit has also used EKS to implement a microservices architecture, allowing it to rapidly develop and deploy new features and services. This has enabled Intuit to innovate at a faster pace and respond quickly to market demands.
