AWS ECR - Elastic Container Registry
Amazon Elastic Container Registry (ECR) is a managed AWS Docker container registry service. It allows developers to store, manage, and deploy Docker container images. ECR is integrated with other AWS services such as Amazon Elastic Container Service (ECS), Amazon Elastic Kubernetes Service (EKS), and AWS Lambda, making it easier to deploy applications using these services.
