The document discusses DevOps as a process model that integrates development and operations, emphasizing its evolution, tools, and best practices. It highlights the significance of performance metrics like MTBF, MTTR, and MTRS, along with common pitfalls and bad practices in implementing DevOps. Additionally, it lists various DevOps certifications and tools across different stages of the software life cycle.

- 2. Development + Operations+ Quality • One can state DevOps as a process model which has insightfully shifted the corporate culture introducing few frame works in software life cycle stages. • There is a no defined definition for this DevOps. • Companies moving with Agile, continual service improvements, Lean etc. has given way to new ideas, processes and concepts. • Years of knowledge and simplifications drove us to a beautiful and meaningful combination of: Technology + Quality assurance + software engineering
- 3. DevOps history line 2009: DevOps initial summit @Belgium 2011-12: DevOps tools developed and increased its necessity in IT 2014: Corporate companies started witnessing +ve trends. Journey started across industries and platforms
- 4. Life cycle stages: • This life cycle components are skeletal structure for all companies. • As per IT infrastructure, vision and policies, few more stages are added, modified or renamed. Examples: Analyze, Edit, Monitor/ Diagnose, Debug, Tune, Feedback and operate. Lifecycle/ feedback/ improve ments

- 6. DevOps: Bad practices Ref: http://web.devopstopologies.com 1. Dev and Ops Silos: ‘Throw it over the wall’ split between Dev and Ops. 2. DevOps Team Silo: The DevOps Team Silo (Anti-Type B) typically results from a manager or exec deciding that they “need a bit of this DevOps thing” and starting a ‘DevOps team’ (probably full of people known as ‘a DevOp‘). 3. Dev Don't Need Ops: Assuming that Ops is now a thing of the past, the developers might underestimate the complexity and importance of operational skills and activities, and believe that they can do without them.
- 7. Performance Indicators or success factors • DevOps is based on performance metrics or called as success measure factors: MTBF (mean time between failures): It is the average time that an IT service or other configuration item can perform its agreed function without interruption. This is measured from when the configuration item starts working, until it next fails. MTTR (mean time to repair): The average time taken to repair an IT service or other configuration item after a failure. MTTR is measured from when the configuration item fails until it is repaired. MTRS (mean time to restore service): The average time taken to restore an IT service or other configuration item after a failure. Fault tolerance: The ability of an IT service or other configuration item to continue to operate correctly after failure of a component part. CI (configuration item): Any component or other service asset that needs to be managed in order to deliver an IT service. Service availability uptime. Financial aspect in terms of release: Terminology definitions : https://www.axelos.com/Corporate/media/Files/Glossaries/ITIL_2011_Glossary_GB-v1-0.pdf
