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.

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."
"The ability to use an image with the software built into it, rather than just the software, is beneficial."
"The most valuable feature of Docker is automation. When I deploy the solution I am confident it will work anywhere. It is reliable and easy to use."
"Docker allows you to create small applications and containerize them. You can create multiple such application containers that can run simultaneously on the Linux operating system. In a DevOps environment where multiple teams are creating applications, developing new versions, and deploying applications frequently, Docker is very helpful. The greatest benefit of the solution is that you can create applications and multiple versions of the same application, distributing them across various Linux platforms. Setting up Docker is very quick; whereas setting up a Linux operating system can take five to ten minutes, you can set up a Docker-based Linux OS container within minutes. For developers who frequently create and deploy applications, Docker makes it easy to quickly develop, deploy, and run the latest versions. The solution’s stability is great. I rate it a nine out of ten. Regarding scalability, Docker doesn't require any separate configuration for multiple users. If you are trying to create an application quickly for testing or development purposes, Docker is the best tool available."
"Docker has had a significant positive impact across development and training, and the biggest improvement has been the elimination of environment inconsistencies, which used to be one of the main sources of friction in product development and onboarding."
"The solution's customer service is good."
"It is neat and very flexible."
"Previously we had to set everything up for small deployments in the environment, but with Docker, we can directly run the application in a container and pull any images."
"The deployment is quite fast, which is beneficial."
 

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 can improve the integration with Microsoft Windows. It does not support native installations."
"The command line interface could be more intuitive. I constantly struggle with it."
"We are facing multiple issues with the solution's stability."
"The learning curve with Docker is huge and extensive"
"I would like to see better management layers."
"The stability could be improved."
"I would love to have it available on Linux."
"If you install Docker on a host, it creates its own firewalls. It can become an issue."
 

Pricing and Cost Advice

Information not available
"I use the solution's open-source version."
"We use the open-source version."
"Docker is a free-to-use solution. However, Docker Enterprise is not free."
"Docker is a free open-source solution. However, there is the Docker Enterprise which is a paid solution."
"It's free."
"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."
"We are using the open-source version of the solution."
"Regarding pricing, we primarily use AWS for our deployments since we have funding for it. We don't spend much on Docker-specific services, just the containerization product. Docker Hub isn't particularly expensive either, so overall, the pricing is pretty reasonable."
