Rocky Linux and Docker on CentOS are key competitors in managing enterprise infrastructure, each excelling in different areas. Docker on CentOS has a slight edge in environments requiring containerization due to its extensive feature set.
Features: Rocky Linux offers stability, enterprise-grade compatibility with CentOS, and community-driven development. It ensures long-term support, making it a reliable choice for consistent operations. Docker on CentOS enhances application deployment through container isolation, image-based packaging, and portability, providing a streamlined experience across different environments.
Room for Improvement: Rocky Linux could benefit from more streamlined integration tools and enhanced user interface options. Increasing the frequency of official patches would also help in improving its security offerings. Docker on CentOS could improve support for deprecated features, provide better security updates, and enhance documentation for its newer versions to counteract issues arising from its previous deprecation period.
Ease of Deployment and Customer Service: Rocky Linux leverages a straightforward installation process with thorough documentation, aiding in smooth deployment transitions. It draws significant support from its community. Docker on CentOS offers rapid deployment through its container mechanisms, supported by a robust ecosystem and community resources, which enhance operational efficiency.
Pricing and ROI: Rocky Linux, being open-source, eliminates licensing fees, reducing initial setup costs while maintaining enterprise-grade service. Docker on CentOS may involve costs for its enterprise features, but the investment is justified by its improvement in deployment speed and operational effectiveness, offering substantial long-term ROI.
I could say it is maybe forty percent compared to before using Docker.
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.
After switching to Docker on CentOS from VMs, I have seen a return on investment, saving 40 to 50 percent of our money as well.
When it comes to return on investment, a lot of money is saved since we moved from a purchased license to the open source provided by Rocky Linux.
ROI has been good as we have significant open source community involvement.
I have seen a return on investment since there was definitely money saved at the time due to the lack of need for licensing since Rocky is available openly.
We purchase the software and product from them, so when I have an issue with Red Hat or Docker on CentOS or Kubernetes, I create a ticket with the partner who works directly with the respective teams.
Most things can be easily found as resources online to help resolve those issues.
Docker has lots of documentation and community support.
The support level is extraordinary, providing on-time assistance.
We have not yet needed to contact a vendor regarding Rocky Linux.
Even if we raise a support ticket, we receive a resolution or a reply from the team within two business days.
if we need more resources, we can just spin up a new Docker image, so scalability is good.
If you have good hardware, you can scale Docker on CentOS as required.
Docker on CentOS is scalable; I can build virtual machines, EC2 instances, and scale from zero to however many I want.
Even if the server is not responding and we want to attach the volume on another instance or a temporary instance, it is very easy and straightforward with no hiccups.
It has handled growth or changing needs well.
The scalability is quite good, though there are some issues with Rocky Linux.
Docker on CentOS is not stable anymore because it is not actively being maintained.
Docker on CentOS is quite stable.
Docker on CentOS is stable, but as I mentioned, there are some improvements needed.
Rocky Linux is stable, scalable, and it is very much easier to use.
Rocky Linux is stable.
To achieve a higher rating of 9 or 10, they might need more automation features.
The metrics of the containers in Docker on CentOS can also be improved, along with the monitoring part which needs enhancement.
The main issue comes from running out of space; that is when crashes happen.
It is based on customer requirements, as they might want to use Rocky Linux or Ubuntu, depending on their needs.
Rocky Linux could be improved by having more integration with Kubernetes.
Currently, it takes more than one month to release a new package or kernel, so speeding that up would help reduce reported vulnerability remediations.
there is no licensing cost required.
There is no licensing in Docker on CentOS.
My experience with pricing, setup cost, and licensing was all good; cost was never an issue.
We switched to Rocky Linux because of the license price, and in our business, we don't need to have a higher cost as that is not a good idea.
There is no extra cost for a license if we are purchasing Rocky Linux from the AWS Marketplace.
Rocky Linux is free, and I can download it and deploy it in whatever environment I have, whether it be H3C, VMware, or Hyper-V.
It also ensures a consistent environment where applications will work on every machine, not just the developer's machine, and offers resource efficiency, such as no full OS per application, allowing me to share my infrastructure with multiple containers and applications.
Docker on CentOS has positively impacted my organization by making testing easier. I do not have to install older versions of applications and then make my system or service study.
The benefits are significant as it is easy to operate and maintain, making it more flexible.
Rocky Linux has positively impacted my organization, specifically through cost savings, because we did not have to buy any licenses or extra licenses of other distros, such as Oracle or Red Hat.
For production deployment, Rocky Linux is a great choice because it offers full RHEL compatibility without licensing costs, along with strong community support.
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.
