Eli Chavez - PeerSpot reviewer
Solution delivers consistent reliability and high stability
ECR is reliable, however, I don't consider it the best container registry available. The main reason is that it is not entirely based on the original Docker registry. For instance, I prefer Azure's ACR because, in ACR, there is no need to create repositories; I simply push. Logging into the repository and specifying the path automatically creates everything. This structure resembles an S3 setup with a container registry layout.

Enhance security with automated vulnerability detection and private registry support
We use Harbor for Docker containers to build from our GitLab CI/CD pipeline. This pipeline then automatically pushes to our Harbor instance. We are still working on storing Helm charts in the Harbor instance as well Harbor has improved our organization's security and stability in our container…

Quotes from Members

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

Pros

"The Docker compatibility that ECR offers is probably the most beneficial aspect of the solution."
"ECR provides robust security features, including image scanning and vulnerability assessment, supported by AWS identity and access management for fine-grained access control."
"Amazon ECR has a native integration with all AWS services, making it convenient for use within the AWS ecosystem."
"There are no issues. The service is remarkably stable."
"The solution is very stable."
"The autoscaling functionality is the main beneficial feature of Amazon ECR. It simplifies management, but some configurations can complicate things a bit."
"It is easy to use compared to other container registries."
"The main feature I value is the ability to deposit and retrieve images."
"Right now this is the leading product in this category."
"The most valuable feature of Harbor is its security scanning capability."
 

Cons

"There were a few issues related to the roles, policies, and retrieval of data when trying to fetch images for deployment on Amazon ECS. This can involve permissions and configuration complexities."
"The UI for managing ECR and other services could be improved. It could be user-friendly compared to other cloud services."
"It would be great if they could also provide a reference to fix the errors or vulnerabilities in the images rather than just notifying us about them."
"Amazon ECR needs to improve its downtime."
"Providing more ways to scan the image integrated with ECR would enhance security in the software development life cycle."
"Amazon ECR should include integration with Docker Hub."
"I suggest making it more aligned with the Docker registry version two API specification."
"The documentation could be improved."
"The product should integrate better with other storage options."
"The GUI needs to improve."
"There is a need for more support for public repositories, like the Google Cloud GTR, which is not as integrated as desired."
 

Pricing and Cost Advice

"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."
"Amazon ECR does not have a high cost."
"The solution's price is reasonable compared to its competitors"
"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."
"The cost of the product is free."
