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."
"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."
"Traditional deployments take more time and builds can be inconsistent across different environments. Docker solves these issues."
"The scalability of Docker is good."
"The solution is stable."
"Docker is convenient and easy to use."
"The stability is excellent."
"The most valuable features of Docker are its security, detailed documentation, and ease of use, and the Docker Swarm is not as complex as Kubernetes."
"The solution helps save costs."
 

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."
"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 runtime and security could improve in Docker. Security is paramount in the cloud and important."
"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."
"We'd like knowledge transfer to be easier."
"Docker volumes. When I integrated volumes, I faced challenges. I have not essentially used add volumes to the existing instances."
"The solution could offer better documentation."
"The vendor should release a monitoring tool or include monitoring capabilities in Docker"
"If you install Docker on a host, it creates its own firewalls. It can become an issue."
