Containerization has streamlined microservices delivery and ensures consistent hybrid deployments

The capabilities of Docker on CentOS that I have found the most valuable include its use for Spring-based applications, which significantly enhance the value I derive from it. Docker on CentOS is particularly effective for building distributed applications and microservices. Deployments are smooth and easy, and the integration with Kubernetes is seamless. I have successfully managed 80-plus pods clusters, scaling from 80 to 85 with 140 TPS without encountering any issues. Docker on CentOS's lightweight nature allows for flawless development across environments such as dev, stage, and prod. From my perspective, the experience with the deployment of Docker on CentOS is quite positive, especially for the CI/CD pipeline. The architecture overview includes the use of a Git repository and GitLab CI, which facilitates the Docker build for our Spring 3.x Java applications.

Building consistent QA environments has improved deployments and simplifies troubleshooting

Senior Technical Lead QA at a computer software company with 501-1,000 employees

The best features Rocky Linux offers in my experience are its stability, RHEL compatibility, strong security with SELinux, and reliable package management with DNF. It is also very useful for building QA environments that closely match production. Compatibility has made the biggest difference, allowing me to reproduce production-like, RHEL environments for QA and catch deployment and configuration issues earlier, reducing environment-specific failures. For QA, Rocky Linux's strong community support and predictable updates are highlights that make it easier to maintain consistent and reliable test environments over time. Rocky Linux has impacted my organization positively by helping to create stable, production-like environments for QA and development, thus improving consistency, reducing environment-related issues, and making deployments more predictable. We have seen fewer environment-related issues and less time spent troubleshooting differences between QA and production, which has made testing and deployments more consistent.
