CentOS and MySQL on Ubuntu compete in the server operating system and database management space respectively. While CentOS is praised for its cost-effectiveness and long-term stability, MySQL on Ubuntu is favored for its features and ease of integration.
Features: CentOS stands out with its stability, cost-effectiveness, and compatibility with Red Hat, offering lower memory consumption and robust performance on minimal hardware. MySQL on Ubuntu is appreciated for its high availability, scalability, and reliable performance, especially for relational tables. Its ACID compliance and security features make it a preferred choice.
Room for Improvement: CentOS could improve its NFS client's performance, enhance documentation, and address instability concerns. Backward compatibility is also desired. MySQL on Ubuntu faces challenges in scaling complexities and integrating new data formats like JSON. Users seek performance enhancements and auto-optimization features for better security.
Ease of Deployment and Customer Service: CentOS is commonly used in on-premises environments, with users benefiting from community forums in lieu of official support. Red Hat offers customer service for those who opt for it. MySQL on Ubuntu is widely used across cloud environments, enjoying robust community support and distributed assistance due to its open-source nature.
Pricing and ROI: CentOS provides significant cost savings with its open-source model and only incurs costs with optional Red Hat support. This results in substantial ROI for enterprises valuing stability. MySQL on Ubuntu also leverages its open-source nature to keep operational costs low, making it advantageous for reducing hardware and cloud expenses. Both solutions offer considerable ROI with time and cost efficiencies.
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 audit trail MySQL provided also meant zero untracked data losses in production.
I have seen a return on investment with MySQL on Ubuntu because I can say that everything we can do here is save money and time, and even we are using a small number of team to handle it.
I have indeed seen a return on investment, particularly in time saved, as using MySQL on Ubuntu has proven to be 15 to 20% quicker than building a Postgres database.
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.
I used AWS support, and they are very quick to respond.
Whenever we can, we call the support and they fix the problem right away.
GitHub Copilot provides substantial information that helps when encountering errors.
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.
When running on EC2 instances, for example, I can scale it from zero to 10,000 machines or even higher.
Clustering is useful because that helps with high availability and scalability.
MySQL on Ubuntu provides excellent reliability for scalability needs.
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.
MySQL on Ubuntu uses the InnoDB engine, which has ACID properties integrated.
In real-world production use, it has been consistently proven across startups, mid-sized companies, and large organizations as well.
MySQL on Ubuntu is stable; both the MySQL component and the Ubuntu component are very stable, popular, and actively maintained.
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.
Scaling out is much harder to do. Even though a master-slave setup can help maintain a real-time backup or offload queries, achieving true horizontal scaling with numerous nodes at once can be tricky with MySQL on Ubuntu.
A more self-tuning approach to index optimization and query execution would reduce that burden, particularly for teams that focus more on application logic than database administration.
The only area where I would say I have seen potential for improvement is occasional slowness, but I cannot really attribute it to the product; it could also be the design of the database and the queries.
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.
Since MySQL on Ubuntu is quite lean, it results in low operational costs, making it favorable from a pricing perspective.
We can reduce licensing cost saving with MySQL on Ubuntu because there is no cost.
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.
It extends with volume very well. Most RDBMS don't scale very well, but this one scales very well and has been very reliable and highly available.
By putting it in MySQL on Ubuntu, even if the node went down, the database would come back up.
Since our EC2 instance is deployed in a virtual private network with MySQL on Ubuntu installed, it is protected from unauthorized access and use, and we have also encrypted the data in MySQL.
