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.

Effortless setup and comprehensive image scanning enhance project efficiency with minimal manual intervention
The challenge I encountered while using the VMware Harbor Registry is that sometimes the default credentials get overwritten, so we have to restart Harbor to make it function as before. The default credential rewrite is one of the major pains with Harbor, so this has to be improved. They can expand more into the known issue section and support for the older versions. We did check the documentation as well as some of the issues mentioned in GitHub, but they weren't that useful.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"ECR provides robust security features, including image scanning and vulnerability assessment, supported by AWS identity and access management for fine-grained access control."
"The technical support services are excellent."
"There are no issues, the service is remarkably stable, and it's rare to see the registry experiencing downtime unless perhaps AWS itself is completely down."
"The main feature I value is the ability to deposit and retrieve images."
"The most tool's valuable feature is image scanning."
"The most valuable feature of the solution is the scanning of images for vulnerabilities."
"The integration with AWS services is very easy, and the deployment and initial setup are pretty straightforward."
"I recommend using AWS services for their availability, scalability, performance, and observability."
"The most valuable features of VMware Harbor Registry are that it's lightweight and the in-built Trivy solution, which I find valuable mainly for the vulnerability scanning that it publishes."
"It is very convenient to automate consistently deploying it to a Kubernetes environment to see how it performs."
 

Cons

"When it comes to pricing for Amazon ECR, that is the only area AWS has to look into."
"Improving the documentation for easy understanding will help bring in more clients to use Amazon ECR."
"I suggest making it more aligned with the Docker registry version two API specification."
"I would appreciate a feature in Amazon ECR that allows direct image downloads from open source into ECR, bypassing the current need to first pull the image to my server."
"ECR is reliable, however, I don't consider it the best container registry available."
"If Amazon ECR had CI/CD also integrated into it, then it would probably be better."
"Amazon ECR should improve the integration with Amazon CloudWatch. For example, allowing us to monitor the queues better. Additionally, some of the features could be made more accessible."
"Amazon ECR's manipulation capability of tags needs to be improved."
"The image scanning in VMware Harbor Registry is quite limited compared to other specialized image scanning tools."
"The default credential rewrite is one of the major pains with Harbor, so this has to be improved."
 

Pricing and Cost Advice

"The solution's price is reasonable compared to its competitors"
"The product is expensive."
"The solution's prices are high in India as compared to the US."
"The main difference between Amazon ECR and other solutions, like Google Kubernetes Engine, is that I haven't personally used GKE. However, I know that GKE costs around $60 per month, which is quite cost-effective."
"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."
"Amazon ECR does not have a high cost."
