    Study Notes

    ITIL Evolution

    • ITIL 3 defined Problem Management as a function within IT Service Management (ITSM)
    • In ITIL 4, this function evolved into "Problem Management Practice"
    • The objective of Problem Management Practice in ITIL 4 is to deliver problem management outputs effectively
    • The change in ITIL 4 focuses on collaboration and value delivery efficiency

    ITIL Principles

    • There are seven guiding ITIL principles.
    • Focus on Value: Organizations should ensure all actions deliver value to stakeholders, especially customers.
    • Start Where You Are: Utilize existing systems and processes as a foundation for improvement.
    • Progress Iteratively with Feedback: Break down tasks into smaller, manageable steps and gather feedback after each step.
    • Collaborate and Promote Visibility: Foster an environment of collaboration and transparency within the IT team.

    DevOps Concepts

    • Represents a set of principles and practices that aim to streamline software development and deployment.
    • The DevOps methodology emphasizes collaboration, automation, and continuous improvement.

    Three Central Elements of DevOps

    • People: A DevOps team consists of diverse professionals who contribute to all stages of the software lifecycle.

      • Product Owner: Responsible for the product backlog.
      • Developer: Creates code and performs unit testing.
      • Tester: Develops and executes test scripts.
      • Architect: Designs software architecture.
      • IT Security: Manages IT security aspects.

    • Process: The DevOps process revolves around a Continuous Integration and Continuous Delivery (CI/CD) pipeline, composed of:

      • Continuous Integration (CI): Automates code integration, testing, and builds, minimizing errors.
      • Continuous Delivery (CD): Automates deployment to the test environment, requiring human intervention for production deployment.
      • Continuous Deployment (CD): Automates deployment to production, building upon Continuous Delivery principles, with a complete end-to-end automated approach.

    • Technology:

      • Choice of tools is crucial for success.
      • Tools can vary depending on the technology stack and specific needs of the organization.
      • Examples of widely used source code repositories include Git and Subversion.
      • Git is a Distributed Version Control System (DVCS), allowing developers to work on the entire codebase independently.
      • Subversion is a Central Version Control System (CVCS), requiring developers to check out, modify, and check in code to a central server.

    DevOps Principles (CALMS)

    • Culture: Fosters a blameless culture where everyone takes responsibility for the product as a whole.

      • Encourage taking ownership beyond individual tasks.
      • Promote innovation and stepping outside comfort zones.
      • Emphasize communication, collaboration, and teamwork.
      • Value experimentation and learning from mistakes.

    • Automation: Automates repetitive tasks for increased efficiency and speed.

      • Aims to reduce manual intervention and errors.
      • Cloud infrastructure provides faster server creation through code.

    • Lean: Adopts the Lean philosophy to streamline processes and eliminate waste.

      • Focus on simplicity and straightforward approaches.
      • Reduce waste through optimizing processes and eliminating defects.

    • Measurement: Emphasizes data-driven decision-making and continuous improvement through monitoring and feedback.

      • Use metrics to track progress, identify areas for improvement, and measure the effectiveness of changes.
      • Implement monitoring tools to track application and infrastructure performance, alerting on warnings or exceptions.

    • Sharing: Promotes collaboration, knowledge-sharing and a culture of learning.

      • Encourages sharing knowledge, experience, ideas, and best practices.
      • Fosters collaboration and teamwork among team members.
      • Reduces silos and promotes a sense of shared understanding.
