Secure

Amazon ECR encrypts your images at rest and in transit using industry-standard encryption algorithms. This means that your images are protected from unauthorized access, even if they are intercepted or stolen.

Encryption at rest: Amazon ECR encrypts your images using AES-256 encryption. This means that your images are encrypted when they are stored on Amazon ECR's servers.
Encryption in transit: Amazon ECR encrypts your images when they are transmitted over the network. This means that your images are protected from unauthorized access, even if they are intercepted in transit.

Amazon ECR's encryption features provide you with peace of mind knowing that your images are protected from unauthorized access. This is especially important for images that contain sensitive data, such as customer information or financial data.

Scalable

Amazon ECR is a highly scalable service that can handle millions of images and terabytes of data. This is important for businesses that need to store and manage a large number of container images. For example, a large enterprise might have thousands of developers working on hundreds of different projects. Each project might require multiple container images, and each image might be several gigabytes in size. Amazon ECR can easily handle this .

The scalability of Amazon ECR is due to its distributed architecture. Amazon ECR stores images in multiple data centers around the world. This means that images can be accessed quickly and reliably from anywhere in the world. Amazon ECR also uses a variety of caching techniques to improve performance.
