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.

Massimiliano Adamo

Linux architect at European Commission

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.
