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
