Containerization has transformed how I run microservices for high-speed web and API workloads
The best features Docker on CentOS offers include its lightweight containers and fast startup. Whenever there was a scale-out required for the APIs, it was immediate, less than 10 seconds to boot up, which was very helpful for the microfinance services. The fast startup and lightweight containers of Docker on CentOS were very helpful because earlier when we used to have these APIs running on the EC2 instances, many instances were required for those services, even though the code was very small. We had to use many EC2 instances instead of using microservices or micro containers like Docker. When we moved to Docker, the scale-out was very fast and very helpful for the business. The boot time with Docker was very less compared to the EC2 instances because running on the EC2 instances required more boot time for the OS, and there was a long delay due to the script execution for a few seconds. Docker on CentOS has positively impacted my organization as it helped us grow the business, and the customer was very happy with the services, thus revolutionizing the business.

Has supported seamless migrations and enabled running complex data workloads securely
The best features Rocky Linux offers include clustering and all the packages from Red Hat.Rocky Linux has impacted my organization very positively because we migrated everything from CentOS and Windows servers to Rocky Linux. Everything is clear, with good packaging, and now it's version 9.6, which is very important for us due to security problems since we are in Europe. Rocky Linux is very good for security and other aspects. Since migrating to Rocky Linux, I've seen specific outcomes such as improved security because CentOS stopped the project, and security patches aren't being released. We need to maintain a system similar to Red Hat, which is very stable and has many features such as file system, topology, and containers.

Quotes from Members

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

Pros

"Those features helped me specifically during my project by making it more stable since it used fewer resources, resulting in a cost-efficient deployment, as the machines that I deployed it on used less of the resources than I thought they needed."
"We can see faster deployments and reduced environment-related issues since adopting Docker on CentOS."
"Docker on CentOS has improved my organization positively, as it is easy to operate and maintain, making it more flexible—you can change any service in the system, delete or remove the service port, and create new ones."
"Docker on CentOS has positively impacted my organization as it helped us grow the business, and the customer was very happy with the services, thus revolutionizing the business."
"Docker on CentOS has positively impacted my organization by improving our time to market."
"In my opinion, the best features Rocky Linux offers are stability, compatibility, and community support, all of which I think are extremely necessary and essential for the distribution, and I find that all three pillars are very supported by Rocky Linux."
"It's very simple to work with, easy to learn, and know where things are."
"The most valuable feature of the solution is its stability."
"Rocky Linux performs excellently in low-latency live streaming and content packaging workflows, as we use it for optimizing compatibility with the streaming platforms, utilizing an optimized kernel for networking, tuning profiles, IRQ affinity, security, reliability, and hardware and driver support."
"Rocky Linux is best for someone who wants good scalability, enterprise-grade stability, substantial community engagement, compatibility with RHEL, and strong security."
"Rocky Linux has positively impacted my organization by making things simpler, especially with not having to escalate privileges all the time using sudo as compared to Ubuntu flavors."
"The experience of working with Rocky Linux is the same as with other Linux distributions; there was no difficulty for me in learning how to work with it."
"It helps us keep our workstations in sync and ensures consistent settings across most of our machines."
 

Cons

"Docker on CentOS can be improved by being in sync with the OS updates."
"Docker on CentOS needs native orchestration and lifecycle management, which are currently limited."
"I have not seen a return on investment because the deprecation made it so there was none, and if anything, the ROI would have been negative since money and time were spent using something that did not progress."
"To achieve a higher rating of 9 or 10, they might need more automation features."
"To be honest, Rocky Linux is almost similar to each Linux distribution, so I have no specific reason why it should offer me its features."
"I see some performance-related issues, but we are still checking on that, and we don't know if it is related to the OS or the resource; that is something still to be checked from our end."
"I chose a rating of eight out of ten because Rocky Linux must grow more; it is not as comparable to Red Hat, which is why I took off those two points."
"One of the potential issues is that if you don't pay for support, you may need to manage certain aspects on your own and rely on the community for assistance."
"I have certain problems with the tool's DNS part, making it an area where improvements are required."
"Currently, the customer support for Rocky Linux is not fully developed and is in a growing stage; the customer support is also not very responsive."
"To improve Rocky Linux, providing releases for each package, firmware, and kernel more quickly would be beneficial."
"In terms of scalability, you need to have automation tools."
