ECS to EKS: A Step-by-Step Guide for Seamless Migration from AWS ECS to AWS EKS

When it comes to containerized applications, AWS ECS may not always be the most optimal service to use, particularly as your applications and services grow in value and complexity. In this situation, migrating from ECS to EKS (Elastic Kubernetes Services) allows for better workload scalability, powerful orchestration, as well as greater overall flexibility at the services themselves. With EKS built atop of Kubernetes, serves as the backbone of microservices. It facilitates robust features such as automated scaling, self-healing, and workload management, making it perfect for complex microservice architectures.

In this blog, we will break down the migration process observing the movement from ECS to EKS from a higher level. We will highlight the numerous problems developers have to deal with for this migration, ranging from changes in configurations, managing stateful workloads, and mitigating the impact of the switch and downtime.

By employing the appropriate strategy and tools, moving from ECS to EKS becomes much easier than it seems. EKS has seamless integration with other services within AWS ecosystem granting more control over security monitoring and deployment of containerized applications. In addition, Kubernetes ecosystem diversification bestows amazing possibilities such as the utilization of Helm charts for resource management and even multi-cluster resource architecture.

Kapstan, a powerful DevOps automation tool, can significantly simplify this transition. It automates complex tasks, such as configuration management and deployment pipelines, eliminating manual efforts and YAML file complexity when moving from ECS to EKS. With Kapstan’s self-service platform, you can streamline the management of your EKS environment, ensure consistency across deployments, and boost the overall efficiency of your DevOps workflows.

Whether you're new to Kubernetes or looking to enhance your existing EKS deployment, this blog will provide valuable insights, practical steps, and tips to help you migrate from ECS to EKS with confidence. Discover how Kapstan can help you fully leverage the power of Kubernetes and improve your cloud-native application management strategy.
