Study Notes
Advantages of DevOps
- Faster time-to-market by automating manual tasks and streamlining workflows
- Improved quality through emphasis on testing and feedback
- Increased efficiency by reducing time and resources needed to deploy software
DevOps Lifecycle
- A continuous process with each phase informing the next
- Emphasizes ongoing collaboration across all stages
- Phases include: Plan, Develop, Test, Deploy, Operate, Monitor, and Feedback
Plan Phase
- Collaboration between development and operations teams to plan software development process
- Includes planning features, timeline, and resources needed
Develop Phase
- Development team builds software using agile methodology
- Uses version control tools like Git to track changes and collaborate with other team members
Test Phase
- Development team tests software to identify and fix bugs
- Includes automated testing and manual testing by QA teams
- Ongoing process throughout development lifecycle to ensure high-quality software
Deploy Phase
- Operations team deploys software to production
DevOps Fundamentals
- Combines software development (Dev) and IT operations (Ops)
- Aims to deliver high-quality software at a faster pace
- Includes cultural philosophies, practices, and tools to increase an organization's ability to deliver applications and services
Basic Principles
- Collaboration between development and operations teams
- Automation to streamline and speed up software development process
- Continuous improvement to optimize processes and deliver better software
Key Practices
- Continuous Integration (CI): regular integration of code into a shared repository
- Continuous Delivery (CD): building, testing, and deploying software to production automatically and frequently
- Infrastructure as Code (IaC): managing infrastructure using code for easier management and scaling
Operate and Monitor Phases
- Operations team manages and maintains software in production
- Monitors software to identify and resolve issues, and scales infrastructure to meet demand
Feedback Phase
- Reviews software development process to identify areas for improvement
- Gathers feedback from users, identifies bottlenecks, and implements changes to improve software development process
Tool and Technologies
- Version control: Git
- Build automation: Jenkins and CircleCI
- Deployment automation: Ansible and Puppet
