- What is DevOps?
DevOps is a software development methodology that combines software development (Dev) with information technology operations (Ops) participating together in the entire service lifecycle, from design through the development process to production support.
2. The goals of DevOps
- Fast Development Methodologies
- Fast Quality Assurance Methodologies
- Fast Deployment Methodologies
- Faster time to market
- Iteration & Continuous Feedback (strong and continuous communication between stakeholders — the end users and customers, product owners, development, quality assurance, and production engineers)
3. The benefits of DevOps
Environment Stabilization
Enforces consistency, increase up-time
Shorter Development Cycle
Manage requirements and code-repository
Increased Release Velocity
Continuous build, push-button deployments
Reduced Defects
Regiment processes, automated testing
Process Metrics
Track both time at each stage, and the errors and exceptions
4. The steps of DevOps
- Plan: task management, schedules
- Code: code development and code review, source code management tools, code merging
- Build: continuous integration tools, version control tools, build status
- Test: continuous testing tools that provide feedback on business risks, determine performance
- Package: artifact repository, application pre-deployment staging
- Release: change management, release approvals, release automation
- Operate: infrastructure installation, infrastructure changes (scalability), infrastructure configuration and management, infrastructure as code tools, capacity planning, capacity & resource management, security check, service deployment, high availability (HA), data recovery, log/backup management, database management
- Monitor: service performance monitoring, log monitoring, end user experience, incident management
