• This is a major practice area within DevOps. - In
engineering, reliability describes the ability of a system
or component to function under stated conditions for a
specified period of time.
• In IT this includes availability, performance, security, and
all the other factors that allow your service to actually
deliver its capabilities to the users.
What is reliability
engineering?

• According 2016 Devops Survey- Key Success Metrics
are:
– Deployment Frequency
– Lead time for changes
– Change Failure rate
– Mean Time to Recovery (MTTR) (< 1hr in High Performance
organizations
)
• 90% Production issues are software problems.

• Parick Debois (Father of Devops) identified four key areas of DevOps:
• We're going to use this to illustrate a holistic approach to reliability
engineering
– 1&3 – Design for Operations
– 2&4 – Operate for Design
Four key areas of Devops

• In design for operation , how you construct your
system to be maximally reliable and maintainable in the
first place, feeding from the project into operations.
• In operate for design , about the practices within
operations, and how to radiate all information from
production back to the project per the feedback loop.
• When you bring together both practices, you have the
DevOps take on reliability engineering.
