AWS ECR is very helpful during CI/CD deployments. I use ECR for storing Docker images. When I push our code to GitHub, the CI/CD pipeline builds the image and stores it in ECR, and then EC2 deploys it by pulling that image.

I can store multiple versions of images, and I can keep them for a long time. I can also customize the retention policy—for example, if I set the limit to 10 images, then once it crosses that limit, older images are deleted automatically. ECR integrates easily with multiple AWS services, and I can grant access to other AWS accounts based on our requirements. I can also create private images that are only accessible within my AWS account. Review collected by and hosted on G2.com.

This is difficult, especially when setting up IAM access and connecting it with EC2. It also feels like vendor lock-in, meaning our project will heavily depend on an AWS account. On top of that, it isn’t the cheapest option; the price is high. Sometimes the size increases, which consumes storage and adds to the cost. Debugging is also difficult.
