Automation has streamlined server setup and has ensured consistent configurations
One of the best features Ansible on CentOS 10 offers is agentless automation. I particularly appreciate playbooks, which is one of my favorite features, along with configuration management and reusable roles. Agentless automation and playbooks stand out for me because they enable me to manage remote servers over SSH without requiring an Ansible agent on each machine. Playbooks use simple YAML files to automate tasks such as installing packages, configuring JINX, and managing services seamlessly. The error handling and reporting in Ansible on CentOS 10 help identify failed tasks and troubleshoot deployment issues more easily. Ansible on CentOS 10 has strong security capabilities for infrastructure automation, including SSH-based access, privilege escalation controls, and Ansible Vault for encrypting sensitive data, which I believe is excellent for AI-assisted automation. Ansible on CentOS 10 integrates well with AWS services, particularly EC2 for server provisioning and configuration.

Containerization has accelerated testing cycles and consistently reduced time to market
Docker on Ubuntu 18.04 LTS is a very mature product, and I don't think there is a lot of improvement that they need to do on their end. The Docker team is coming up with new features, and integration with the IDE, for example, would be amazing. Support on Windows is not so great from Docker, so that is something that they could examine. I chose nine out of ten for Docker on Ubuntu 18.04 LTS because I think they could improve a little more on optimization. It sometimes demands a lot of RAM and computing power, so that is one area that the Docker team could improve upon.
