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.

Centralized control has streamlined multi‑cluster management and automated application deployments
The best features of Rafay Kubernetes Operations Platform are the centralized multi-cluster management, built-in RBAC policy for managing role-based access control, cluster lifecycle management, multi-cloud and hybrid cloud support, and centralized monitoring. Rafay Kubernetes Operations Platform's RBAC policy helps my team by giving each user specific roles for managing the cluster, which makes RBAC integration easier and ensures that users do not have access to all clusters, thereby increasing security. The multi-cloud support stands out for me as it supports different cloud environments on a single platform, including Azure, AWS, and GCP clusters, which helps me manage clusters working on different platforms.

Quotes from Members

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

Pros

"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."
"Docker is very reliable. It's easy to scale, and it's very stable."
"The deployment is quite fast, which is beneficial."
"Docker is convenient and easy to use."
"Traditional deployments take more time and builds can be inconsistent across different environments. Docker solves these issues."
"Docker packages up an application as a single item that you can then run without the need to install or configure it to work on any specific machine."
"Docker's containerization property is its main selling point."
"This makes our publisher fast and our containers are isolated from each other."
"Rafay Kubernetes Operations Platform has positively impacted our organization by increasing overall productivity as a team because we are a big team with many people working on Kubernetes clusters on different public clouds."
"I have seen a return on investment, with key benefits including fast deployment cycles, improvement in security and management, reduced downtime, and improved time spent on cluster management."
 

Cons

"The Kubernetes blocks need improvement since Docker has many holes in it."
"Deployment could be quicker."
"There can be challenges with port mapping, however, that's not related to Docker itself."
"Docker management is very difficult when we have a large number of nodes."
"Marketing of Docker is one area that needs to improve."
"The stability could be improved."
"Owing to a few shortcomings in its stability, I would say that its stability can be improved."
"Sometimes, it can become heavy and cause performance issues."
"Rafay Kubernetes Operations Platform should have lower licensing costs for smaller organizations like mine, and it could integrate third-party tools as well."
"From a normal point of view, most things are good with Rafay Kubernetes Operations Platform, but I think there is a bit of a learning curve for new users unfamiliar with the platform, as it sometimes takes time to understand what exactly we are doing there and how everything works."
 

Pricing and Cost Advice

"Customers pay for the license through a yearly subscription model, where they pay per license. This means that the license is based on a subscription, and the customer pays annually for each license they use."
"Docker is a free-to-use solution. However, Docker Enterprise is not free."
"The product is not expensive."
"There is a license needed to use Docker."
"Docker is a free open-source solution. However, there is the Docker Enterprise which is a paid solution."
"Docker is a free open-source solution."
"The current cost for us is nothing as an open source."
"This is an open-source solution, so there are no licensing costs."
