Has supported container workflows through fast image handling and seamless service integrations
The most valuable feature of Amazon ECR is that we can push and pull faster than other similar products. It means saving and retrieving more efficiently. This is not manual dragging and dropping, but rather programmatic taking and saving. I have used Amazon ECR with Lambda, EC2, and EFS. These are integrable services where you can call Amazon ECR from anywhere in AWS. If my product is not always dependent totally on Amazon ECR only, but if the product is dependent on Amazon ECR only, then having a low time to load, low time to save, and a faster containerizing process time would affect the software's response time. This is important.

"If Amazon ECR had CI/CD also integrated into it, then it would probably be better."
"The Amazon ECR interface could benefit from improvements to enhance user experience."

"The product is expensive."
"My company currently has Amazon ECR under the pay-as-you-go model. The tool is more affordable than Azure Container Registry, and it's worth the money."
