Executive SummaryUpdated on Apr 20, 2025

Azure Container Registry and Amazon ECR are both key players in the container management category. Amazon ECR seems to have an upper hand due to its ease of use and cost-effectiveness, despite Azure's advanced features and security enhancements.

Features: Azure Container Registry provides geo-replication, role-based access for enhanced security, and seamless integration with Azure services. It also allows for comprehensive visibility into Docker images and logs. Amazon ECR offers ease of use, integration with AWS services, centralized management, image scanning capabilities, and support for multi-region tasks with a strong focus on security and scalability.

Room for Improvement: Azure Container Registry users have reported accessibility issues, unexpected downtime, and a need for robust auto-scanning capabilities. Improvements in access key management and image stability are also desired. Amazon ECR could improve integration with other cloud services and provide better documentation for newcomers. Enhancements in IAM management and real-time alerting, as well as deeper integration with security tools, are noted areas for improvement.

Ease of Deployment and Customer Service: Azure Container Registry generally provides reliable service on public and private clouds, but with occasional support inconsistencies. Microsoft’s support structure is comprehensive, yet outsourced support gets mixed reviews. Amazon ECR, while also versatile in deployment, is more praised for robust AWS support and proactive service, leading to a slightly better customer service impression.

Pricing and ROI: Azure Container Registry is reasonably priced with a tiered licensing model, but can be seen as expensive compared to on-premise solutions. Amazon ECR is often more cost-effective, utilizing a pay-as-you-go model with low per-storage costs, resulting in strong ROI from operational efficiencies. Azure’s cost is justified by its features and integration advantages, but Amazon’s competitive pricing makes it attractive.

Helps to store Docker containers and images but deployment can be complex

If there were a way to use containers as tasks directly, that would simplify things. Currently, when we use EC2 instances, scaling horizontally means increasing the instance count by five times, which might not be cost-effective. Maybe using containers directly for tasks could be a better option. Setting up this product initially does take quite a bit of time, and maintaining it also requires effort. Doing it via command line would be challenging, so I find it easier to manage through the interface.

Fast, secure, and has no downtime; it also has a role-based access feature

I'm not an active Azure Container Registry user, but I faced some issues, which Azure rectified after six months of usage. During the deployment, my company had a multi-stage pipeline, so whenever the team deploys via the Docker run command or generates an image, the issue arises. The problem is that whenever a new image is generated, that new Docker image isn't updated in Azure Container Registry, so that's an area for improvement. As soon as the deployment is over, my team has to go to Azure Container Registry to delete the image and start the pipeline, and only then will the image be updated. The new image isn't reflected in Azure Container Registry after deployment. My team had to take extra steps for the new image to reflect. Before 2020, Azure Container Registry didn't have the option to scan vulnerabilities, as I've heard from my team lead. After 2020, that feature was introduced in the tool, so as long as that feature is available, then Azure Container Registry is okay. I can't think of any other features to add to it in the next version.

"Amazon ECR has a native integration with all AWS services, making it convenient for use within the AWS ecosystem."

"The most tool's valuable feature is image scanning."

"In the case of Amazon ECR, there are various valuable features we can see. Currently, there are image-scanning capabilities that we use."

"The integration with AWS services is very easy, and the deployment and initial setup are pretty straightforward."

More Amazon ECR pros

"Azure Container Registry is an easy-to-install, easy-to-configure, and easy-to-deploy solution."

"Feature-wise, the security model and access controls are pretty straightforward and valuable"

"The most valuable feature is that it's easy to download, install and manage."

"Provides secure duplication and the option for service webhooks."

"Pricing is reasonable."

"We like the fact that this is a secure solution, that employs a token-based system, which can be used to manage all the applications under this product."

Cons

"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."

"Deeper integration with other security tools would enhance usability."

"If there were a way to use containers as tasks directly, that would simplify things. Currently, when we use EC2 instances, scaling horizontally means increasing the instance count by five times, which might not be cost-effective. Maybe using containers directly for tasks could be a better option."

"If I could use less code and have more of the user interface provide predictions of the coding required in my CLI or Terraform, that would be nice."

"There could be improvements to the interface of AWS concerning ECR."

"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."

"Providing more ways to scan the image integrated with ECR would enhance security in the software development life cycle."

More Amazon ECR cons

"The solution has become more popular in the last few years but I find that the technical support has not increased their knowledge base, so more knowledgeable support staff can help improve the solution."

"They can improve their scalability."

"The security, dashboards, and monitoring system could be improved."

"We have found that it is sometimes difficult to pull images from the host application."

"The setup process is mildly complex. There is no straightforward management platform, so there's a level of complexity to it."

"The solution could always improve its security measures with regard to access."

"The solution has no areas that need improvement."

"The setup for Azure Container Registry was a bit complex. Still, the main problem was that whenever a new image was generated, that new Docker image needed to be updated in Azure Container Registry."

More Azure Container Registry cons

Pricing and Cost Advice

"The solution's prices are high in India as compared to the US."

"Amazon ECR does not have a high cost."

"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."

"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 product is expensive."

"The Premium version includes some enhancements but is still quite okay with regard to pricing."

"I would rate the pricing four out of ten."

"I have no information on how much Azure Container Registry costs. I know it's the only solution my institution can use, so the cost was approved."

"When using Azure Container Registry, it was $1.5 or $1.6 per day, but I'm unsure how much it costs today."

"Azure is a bit expensive."

"The product is competitively priced."

"Azure Container Registry, has no cost, but you pay for storage service."
