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

Promotes collaboration and knowledge sharing amongst individuals
