Executive SummaryUpdated on Jan 12, 2025

Azure Container Registry and Amazon ECR are major competitors in the container solutions category. Azure Container Registry is preferred for its integration with Microsoft's services and security features, while Amazon ECR is favored for its superior performance and AWS integration.

Features: Azure Container Registry is recognized for its excellent security, management of mixed containers, and automation capabilities with webhooks and CLI. It offers seamless integration with Microsoft services for direct deployments. Amazon ECR provides strong AWS integration, including image scanning, vulnerability assessment, and ease of use. It offers high elasticity, fast response times, and a centralized management console.

Room for Improvement: Azure Container Registry users mention performance issues with VPN connections, accessibility challenges, and the need for better technical support. Desired improvements include auto-scanning for vulnerabilities and enhanced integration options. Amazon ECR users highlight complexities for newcomers, inadequate documentation, and the need for better Docker Hub integration. Improvements in real-time alert systems and user interface enhancements are suggested.

Ease of Deployment and Customer Service: Both Azure Container Registry and Amazon ECR offer public cloud solutions, with Azure also supporting private cloud setups. Azure's deployment is straightforward, though customer support is noted to require a plan for effectiveness. Amazon ECR receives compliments for its integration capabilities and trouble-free deployment, yet Azure's support is seen as needing more responsiveness.

Pricing and ROI: Azure Container Registry offers flexible pricing based on storage needs, ranging from basic to premium tiers. Some users find the costs high, while others appreciate the flexibility. Amazon ECR's pay-as-you-go model is considered cost-effective, with users viewing its pricing as reasonable and satisfactory, especially with AWS tools to manage expenses.

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.

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

"The most valuable feature of the solution is the scanning of images for vulnerabilities."

"The main feature I value is the ability to deposit and retrieve images."

More Amazon ECR pros

"What I like best about Azure Container Registry is that it's fast. It also has 24 x 7 reliability. I didn't face any downtime issues using Azure Container Registry. I also like how secure the solution is, especially as it's from Microsoft."

"The scanning of Docker images is the most valuable feature."

"The portability and elasticity features are the most valuable."

Cons

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

"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."

"Its support for system architecture needs improvement."

"The UI for managing ECR and other services could be improved. It could be user-friendly compared to other cloud services."

"There were some initial connectivity issues, especially when accessing ECR from our on-prem setup."

"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."

"Amazon ECR should include integration with Docker Hub."

"Amazon ECR's manipulation capability of tags needs to be improved."

More Amazon ECR cons

"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."

"They can improve their scalability."

"The building of images on the container is quite cumbersome."

"Implementation needs improvement. We have a lot of open, online sources. Doing a deployment is easy for us. The only issue is when we have VPN connections and we try to pull the images from Container images to the local Dockers, it slows down."

"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."

"Lacks the option of having access keys stored in a master key vault."

"There is a need for a graphical interface instead of writing code in Visual Studio to create images."

More Azure Container Registry cons

Pricing and Cost Advice

"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."

"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"

"The product is expensive."

"Azure is a bit expensive."

"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."

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

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

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

"The product is competitively priced."

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