    Study Notes

    ITIL

    • ITIL is a popular framework for delivering IT services
    • Organizations use ITIL as a standard for defining, developing, building, and operating IT services
    • ITIL is used internally by organizations like Microsoft, IBM, and Hewlett-Packard
    • ITIL V3 includes processes and functions
    • A process is a structured set of activities to accomplish a specific objective (e.g. cooking)

    ITIL V3 Functions

    • A function is a team or group of people and their resources used to conduct activities or processes
    • Examples of functions include networking, Java, and web development teams
    • There are 26 processes and 4 functions in ITIL V3

    ITIL V3 Processes

    • Processes require functions to supply the necessary resources to fulfill their goals

    ITIL 4 Practices

    • ITIL 4 replaced processes and functions with practices
    • A practice extends a process by including capabilities and tools to achieve objectives
    • ITIL 4 combined functions and processes to create practices

    ITIL Principles

    • Prioritize honesty and visibility in communication
    • Communicate progress openly, regardless of positive or negative outcomes
    • Work holistically, ensuring all practices, processes, and functions are interconnected
    • Keep things simple and practical, eliminating unnecessary steps or activities
    • Optimize and automate activities to reduce human effort for repetitive tasks

    DevOps

    • ITIL and DevOps are complementary approaches, not mutually exclusive
    • DevOps combines development and operations teams to achieve goals
    • It promotes cross-discipline collaboration to remove inefficiencies
    • Responsibility is shared across teams, creating a blameless culture for mistakes

    DevOps Elements

    • Three elements support DevOps: people, processes, and technology

    People

    • A DevOps team includes professionals involved in an application's development and operations
    • Examples of DevOps team members include:
      • Product Owner
      • Developers
      • Testers
      • Architects
      • IT Security
    • A DevOps team is created around a specific application (e.g., an internet banking program for individuals and small business owners)

    Processes

    • The Continuous Integration, Continuous Delivery, and Continuous Deployment (CI/CD) pipeline is used in DevOps
    Continuous Integration
    • Provides a central repository for developers and automates processes to reduce errors and compile artifacts
    Continuous Delivery
    • Delivers builds to the test environment and requires human intervention to deploy them into production
    • Aims to deliver code changes, like fixes, faster and safer
    Continuous Deployment
    • Deploys builds automatically to production
    • Considered a build on Continuous Delivery with a fully automated approach

    Technology

    • Choosing the right tools is crucial for DevOps
    • Tools like Git and Subversion support source code repository function
    • Git is a distributed version control system (DVCS)
    • Subversion is a central version control system (CVCS)

    DevOps Principles

    • Known as CALMS

    Culture

    • Emphasizes change in behavioral traits:
      • Taking responsibility for the entire product
      • Stepping out of comfort zones to innovate
      • Encouraging communication, collaboration, and affinity within teams
      • Promoting experimentation

    Automation

    • Enables faster delivery and provides rapid feedback
    • Automates repetitive tasks not requiring human intelligence

    Lean

    • Focuses on simplicity and avoids overcomplicating processes
    • Aims to reduce waste, like defects and convoluted processes

    Measurement

    • Measures outcomes to evaluate effectiveness
    • Uses feedback for automation and monitoring

    Sharing

    • Promotes collaboration and knowledge sharing amongst individuals
