High system load is not automatically a sign of a slow disk. This guide shows how iostat with interval sampling separates real trends from short bursts, how iotop identifies the specific process behind heavy I/O usage, and how metrics like %util and await reliably reveal whether you are looking at a disk problem or an application problem.

Deployer PHP and GitLab CI/CD complement each other perfectly for Magento deployments: GitLab builds and tests, Deployer takes care of the release structure, the symlink switch and the rollback path. Teams that combine both tools correctly end up with a reproducible, team ready deployment process without maintenance window roulette.

"One process per container" is one of the most frequently quoted Docker principles, and one of the most frequently misapplied. What the principle really means, where it makes sense, and when Supervisor, s6-overlay or dumb-init are the better decision.
