CentOS and Docker on Ubuntu compete in the field of IT solutions, with CentOS focusing on stability and Docker on Ubuntu offering modern integration. Docker on Ubuntu has the upper hand due to its integration capabilities and ease of container management.
Features: CentOS is noted for stability, ensuring compatibility with RHEL and minimal but reliable updates, making it ideal for web and database servers. Docker on Ubuntu excels with its strong containerization capabilities, quick setups, and robust support within the Ubuntu ecosystem, aiding productivity through microservices management.
Room for Improvement: CentOS faces challenges with scaling and the stability of updates, along with limited long-term support. Users seek better integration with modern technologies. Docker on Ubuntu could benefit from improved networking and storage configurations and more user-friendly tools, highlighting a need for simplified learning curves and enhanced documentation.
Ease of Deployment and Customer Service: CentOS supports primarily on-premises and hybrid cloud environments, with a lack of formal technical support, relying on community resources. Docker on Ubuntu is suited for public and hybrid cloud setups, supported by a strong community and extensive documentation, with both platforms relying on user communities for customer service.
Pricing and ROI: CentOS is a cost-effective, open-source solution offering substantial savings, with possible support via Red Hat licenses. Docker on Ubuntu is free with no licensing fees, though skilled personnel needs can drive indirect costs. Both platforms offer strong ROI through reduced operational expenses and infrastructure optimization.
I have seen a return on investment, particularly in terms of money saved because I do not pay for the servers.
The money saved was significant, approximately fifteen percent of our IT budget.
It saved a lot of time through troubleshooting, which gives us substantial room for improvement in terms of fixing things.
The main return is time-saving, as it provides less setup time, fewer errors, and improved developer productivity.
You need some type of operating system and a container engine, and these two are best in class.
There is a pipeline for it, and the time saving occurs because whenever a developer pushes anything, that goes into the Docker container and builds it.
I would rate the customer support for CentOS a 10 on a scale of 1 to 10.
I've seen many people across the globe interacting, and when users encounter issues, the community provides solutions.
I would rate the documentation about eight in terms of usefulness.
The customer service for Docker on Ubuntu and their technical support are pretty good, especially since the documentation is pretty robust.
Amazon's customer support is brilliant, with very quick response times.
The documentation is good, especially when using AI tools that utilize Docker's information for support.
CentOS is scalable and user-friendly without requiring complex configurations.
It allows users to scale resources vertically for upgrading hardware and horizontally by adding more servers, making it suitable for modern web hosting and containerized applications.
CentOS's scalability for my organization has handled growth and changing needs smoothly.
In some cases, Docker on Ubuntu is not enough for all the complexity of the applications, and I have to go to the next level with Kubernetes.
Ubuntu is very stable as an operating system, and Docker scales well when used properly across projects and environments.
Using Docker on Ubuntu together is a common configuration, and you can deploy it directly on server hardware using virtual machines or in the cloud, scaling however you wish.
CentOS is stable, reliable, flexible, and very useful.
CentOS's simplicity and stability make it easy to use.
I believe CentOS is stable, but we are gradually moving away from it.
Docker on Ubuntu is very stable.
Docker is continually optimized by the Docker company, and Ubuntu is also continually optimized.
Docker on Ubuntu is very much stable; it is one of the most stable solutions that you can find.
The documentation and support could be improved, along with compatibility with newer hardware as hardware continually evolves over time.
Kernel parameters, sysctl config details, tuned profiles, process prioritization, optimized disk, and input scheduler choice are all points for performance optimization.
CentOS RADIUS server handles sensitive authentication data, so improving security is the priority.
Code sharing ability exists in GitHub and other tools, but in Docker on Ubuntu, other users we are sharing with do not have options like edit and update the code.
While Docker itself has no cost, the Docker repository and Docker Hub could improve their pricing, especially for startup companies.
It is completely complex to understand the networking in Docker on Ubuntu and Kubernetes clusters, as well as the ephemeral nature of the network and storage.
There was no cost in terms of deploying it or getting the license for it.
Regarding pricing, setup cost, and licensing for CentOS, there is no cost for licensing or setup pricing.
CentOS is a free product with free updates.
99.9% of people will be happy with the open source version, which is open source and free.
I find the pricing for Docker on Ubuntu is not expensive because basically, it is zero.
Docker does not have licensing.
CentOS has helped me most through its enterprise-level stability.
The update cycle changed when CentOS was prioritized for updates, causing stability issues.
In my experience, the best feature that CentOS offers is the network configuration of a device from the command-line interface, which is exceptionally clean.
Docker is the heart of many AI tools that are used, and I have an AI workstation that uses Docker to package up certain capabilities for AI engineering.
The best features that Docker on Ubuntu offers are container isolation, fast startup time, portability, and strong integration with the Ubuntu Linux ecosystem, making it easy to package applications with their dependencies and run them consistently across systems.
Docker on Ubuntu has positively impacted my organization by making our CI/CD pipeline faster because of the multi-stage build, multi-arch build, and the strategy of layering.
