Understanding the core philosophy, principles, and goals of DevOps.
What is DevOps? DevOps is a set of practices, cultural philosophies, and tools that increases an organization's ability to deliver applications and services at high velocity: evolving and improving products at a faster pace than organizations using traditional software development and infrastructure management processes.
Core Concepts & Principles
- CI/CD: Continuous Integration, Continuous Delivery, and Continuous Deployment - automating the build, test, and deployment pipeline.
- Automation: Automating repetitive tasks in development, testing, deployment, and infrastructure management.
- Collaboration & Culture: Breaking down silos between Development (Dev) and Operations (Ops) teams, fostering shared responsibility and communication.
- CAMS Principles: Culture, Automation, Measurement, and Sharing as core tenets of DevOps.
- Infrastructure as Code (IaC): Managing and provisioning infrastructure through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools.
- Monitoring & Logging: Continuously monitoring application and infrastructure performance to ensure availability and gain feedback.
- Agile & Lean: Often incorporates principles from Agile software development and Lean manufacturing to improve workflow and efficiency.
