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 stability is excellent."
"We use Docker to facilitate deployment, updates, and management."
"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 initial setup was easy, and you are only required to run commands."
"The most valuable feature is that it gives you the same environment as on a developer machine as well as a production machine relevant to specifications, with binaries and dependencies all bundled together in a similar fashion in both places."
"Docker is easy to understand and follow, and it provides good scalability to the application."
"Docker's containerization property is its main selling point."
"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."
 

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."
"Unfortunately, base images are not currently available."
"If you install Docker on a host, it creates its own firewalls. It can become an issue. Usually, when you want to install Docker, you need to restart the firewall or restart the active tables on the machine, but this is not the case with Kubernetes. It uses the default set up by the next administrator, but with Docker, you have to restart the firewall and restart Docker before the firewall on the system will be okay. If you do not the rules will not be created."
"There are elements of stability that are problematic. One of the most recent upgrades created a major incident on our cloud, whereby the containers were not restarting automatically."
"Sometimes, it can become heavy and cause performance issues."
"The command line interface could be more intuitive. I constantly struggle with it."
"I have encountered network issues while connecting with microservices. I want to optimize the application layers over the bucket. It should also have better documentation."
"The solution could offer better documentation."
