Which service allows you to securely store container images for applications?

Amazon Elastic Container Registry (ECR) is designed specifically for storing, managing, and deploying Docker container images securely. It provides a fully managed platform that integrates well with other AWS services. ECR handles the complexities of container image storage, including versioning and access control. This allows developers to focus on building applications rather than managing infrastructure.

ECR offers built-in security features such as encryption at rest using Amazon S3 and identity-based access via AWS IAM (Identity and Access Management), ensuring that only authorized users and services can access the container images.

In contrast, Amazon S3 is a general-purpose storage service suitable for a wide array of data types but not specifically optimized for managing container images. Amazon Aurora is a relational database service, while AWS CodePipeline is a continuous integration and continuous delivery (CI/CD) service, not intended for image storage.
