Study Notes
DevOps Lifecycle
- The DevOps lifecycle is a continuous process, with each phase informing the next.
- The lifecycle emphasizes ongoing collaboration across all stages.
Phases of DevOps Lifecycle
- Plan: Development and operations teams collaborate to plan the software development process, including features, timeline, and resources needed.
- Develop: Development team builds software using agile methodology, emphasizing collaboration, flexibility, and rapid iteration.
- Test: Development team tests software to identify and fix bugs, using automated and manual testing.
- Deploy: Operations team deploys software to production, typically using automation tools like Ansible or Puppet.
- Operate: Operations team manages and maintains software in production, monitoring for issues and ensuring security and compliance.
- Monitor: Operations team monitors software and infrastructure to identify issues and ensure performance.
- Feedback: Development and operations teams review the software development process, gathering feedback, identifying bottlenecks, and implementing changes.
DevOps Fundamentals
- Definition: DevOps is a software development approach combining software development (Dev) and IT operations (Ops) to deliver high-quality software at a faster pace.
- Cultural Philosophies: DevOps emphasizes collaboration, automation, and continuous improvement.
- Practices: Key practices include Continuous Integration (CI), Continuous Delivery (CD), and Infrastructure as Code (IaC).
- Advantages: DevOps helps teams deliver software faster, improves quality, and increases efficiency.
Tools and Technologies
- Version Control: Git is a version control system that allows developers to manage and track changes to code.
- Build Automation: Jenkins and CircleCI are tools that automate the build and testing process.
- Deployment Automation: Ansible and Puppet are tools that automate the deployment process.
Basic Principles
- Collaboration: DevOps emphasizes collaboration between development and operations teams to improve communication, efficiency, and effectiveness.
- Automation: DevOps uses automation tools to streamline and speed up the software development process.
- Continuous Improvement: DevOps promotes a culture of continuous improvement, where teams are always looking for ways to optimize their processes and deliver better software.
