DevOps is a set of practices, cultural philosophies, and tools that bring together software development (Dev) and IT operations (Ops). The goal is to shorten the development lifecycle, deliver features faster, and maintain high reliability — all through automation, collaboration, and continuous feedback.
Core Pillars
- docker — containerization, packaging apps with their dependencies
- ci-cd — automating build, test, and deployment pipelines
- container-orchestration — managing containers at scale with Kubernetes
- deploying-to-vps — shipping apps to virtual private servers
- infrastructure-as-code — managing infrastructure through declarative config files
Supporting Topics
- container-registries — storing and distributing container images
- networking-and-security — TLS, secrets, and network fundamentals for production
Why DevOps
Traditional teams threw code "over the wall" from dev to ops. DevOps eliminates that handoff by making teams responsible for the full lifecycle — build it, ship it, run it. The result is faster releases, fewer failures, and quicker recovery when things break.
