Cloud architect at a tech vendor with 10,001+ employees
Modernization has accelerated cloud migration and now delivers resilient, flexible microservices
I consider the best features offered by Azure Container Apps to be power, event-based scaling, and ease of management. The power of event-based scaling and the ease of management have benefited my team and my projects by allowing the applications to be very flexible since they can scale based on process queue sizes or HTTP requests and for many other reasons such as entries in a Redis cache. Azure Container Apps has positively impacted my organization by making the migration of these applications easier, speeding up these migration processes and achieving greater resilience of the applications in the cloud. I have measured that impact in terms of improvements in resilience, which are very important because we move to having microservices deployed in several availability zones, with autoscaling, and as a result, they are very flexible and very reliable.

Local container testing has boosted development speed but still needs lower battery and memory use
The main thing that really frustrates me about Docker is how much battery power it consumes on a Macintosh. I really am not a fan of that, which leads me to not want to run Docker 24/7 because I do not want my laptop battery to be exhausted by Docker instances running or even the Docker CLI or UI being booted up. I tend to not have it running until I need it, and then I run it and close it. It would be really nice if it did not consume as much battery as it does currently. Docker can definitely be improved by reducing the battery and CPU load that it impacts on a Macintosh. If it were possible for me to run Docker without panicking about the battery running out, that would be excellent. I believe battery is the biggest issue with Docker. The other issue is memory. It seems to consume a lot of memory, and I am not a fan of that. This means that I need to have a really powerful, high-specification Macintosh with a lot of battery and a lot of memory for it to work reliably. I do not always have access to that. If Docker could consume less battery and less memory, that would be magnificent.

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

Pros

"Azure Container Apps has positively impacted my organization by making the migration of these applications easier, speeding up these migration processes and achieving greater resilience of the applications in the cloud."
"Docker is highly scalable."
"Containerization is the most valuable feature. I can communicate to the Docker containers using other containers."
"The deployment is quite fast, which is beneficial."
"The solution offers speed and flexibility."
"The lift and shift creates a lightweight image."
"The most valuable feature of Docker is that it provides a containerized environment. The isolation between the environments is beneficial. Additionally, the solution is easy to use."
"The solution's most valuable feature is the Dockerfile, which makes the life of developers easy. Developers get a real understanding of container creation."
"There are ways of using Docker where you have absolutely no dependencies on the environment that you work in, which allows us to deploy Docker anywhere anytime and has been most valuable because it removes any dependencies when it comes to deployment."
 

Cons

"Azure Container Apps could be improved if the Azure RM Terraform provider could have full implementation of all its capabilities since right now it does not."
"Docker could improve by providing the ability to use the GPU for parallel processing. If there was the capability of using the GPU it would improve the machine learning that I want to use."
"One item that could be improved is the overall stability of Docker."
"We are facing multiple issues with the solution's stability."
"Enhancing artificial intelligence capabilities and cluster management should be a priority. It should facilitate some security management."
"The product does not have an extensive documentation. The tool does not have good scenarios. We have to go through the GitHub repository and investigate similar scenarios. Also, if you are copying multiple things, then you can jeopardize the copy number. The copying aspect also lacks a UI part. We also need to limit the memory."
"The main thing that really frustrates me about Docker is how much battery power it consumes on a Macintosh."
"In my opinion, Docker could improve the experience of container management and monitoring by simplifying the configuration of complex environments and offering more intuitive tools, as I still sometimes feel the need to search for external sources despite its AI Copilot."
"Sometimes, we have sync-up issues where the build doesn't get processed due to these sync issues, causing the build to fail. That's one of the drawbacks I see. When we did a huge sync-up, we faced a couple of issues. It takes some time for us to complete the sync-up. For frequent, smaller updates, we haven't had any issues. However, challenges can arise for those who prefer doing everything in one go. This might not necessarily be due to the tool itself but because of the approach of doing everything in a single batch."
 

Pricing and Cost Advice

Information not available
"Since Docker is an open-source solution, it is free of cost."
"Docker has made some changes and there is an enterprise version that is affordable."
"For commercial use, it's about $30 per month. The license itself isn't expensive, but if there are many users, the price becomes high."
"The solution is an open-source technology and not a commercial product. However, you will have to pay sometimes. The tool's pricing depends on the vendor."
"Docker is a free open-source solution."
"I would rate the pricing of Docker as ten out of ten"
"The solution offers an open-source version that is free and includes a lot of functionality."
"It's an open-source solution, so it doesn't cost anything"
