Study Notes

ITIL

ITIL is a framework for delivering IT services
ITIL is considered the standard for organizations
ITIL provides guidance on how to define, develop, build, and operate IT services
Microsoft, IBM, and Hewlett-Packard Enterprise use ITIL for their internal operating guidelines

ITIL Processes

ITIL processes are structured sets of activities to achieve specific objectives
Processes take inputs and turn them into outputs
Processes are a series of interconnected activities working toward a common goal
Example: Cooking, where steps need to be followed to get the desired dish

ITIL Functions

ITIL functions are teams or groups of people and the tools they use
Examples of functions: Networking team, Java team, Web development team
Teams are selected based on their expertise in a specific area
Processes require functions to perform activities and provide resources

ITIL Practices (ITIL 4)

In ITIL 4, practices replace processes and functions
Practices extend processes by defining activities and bringing capabilities and tools together
Practices combine functions and processes to achieve objectives

ITIL Guiding Principles

Honesty & Visibility: Communicate progress, good or bad, and be open to feedback
Think & Work Holistically: Connect all parts of the service delivery process to ensure alignment and avoid disruptions
Keep it Simple & Practical: Avoid over-complicating processes, only include necessary steps, and eliminate non-value-adding activities
Optimize & Automate: Optimize processes before automating them, automate repetitive tasks to free up human resources for complex work

DevOps

DevOps combines development and operations teams to achieve an objective
It builds on Continuous Delivery practices but focuses on an end-to-end automated approach
DevOps and ITIL are complementary, not mutually exclusive

DevOps Technology

DevOps utilizes various tools to support automation
The choice of tools is crucial, as not all tools are compatible with all technologies
Example: Git and Subversion are both used for source code versioning but operate differently

DevOps Principles (CALMS)

Culture:
- Taking responsibility for the entire product
- Innovating and stepping outside of comfort zones
- Communicating, collaborating, and building relationships
- Experimenting
Automation: Automating repetitive tasks that do not require human intelligence
Lean:
- Keeping things simple and straightforward
- Reducing waste, including defects and convoluted processes
Measurement: Measuring performance and outcomes to understand the effectiveness of the approach
Sharing: Collaboration and knowledge sharing between teams

Source Code Version Control Systems

Central Version Control System (CVCS):
- Server-client relationship for storing and retrieving code
- Developers need to check out, make changes, and check in code
Distributed Version Control System (DVCS):
- Each developer has the entire code on their computer
- No check-out or check-in required
- Faster accessibility, adding, combining, and delivering code
