Exercise: What is DevOps?

Do You Have a DevOps Gap?
Production
Releases
Development
Operations
Change
Requests
•
•
•
•
Production releases are seen as risky
Collaboration between development and operations is strained
Development doesn’t appreciate the realities of operations
Operations doesn’t understand new development strategies

One View: Continuous Delivery
•
Practices:
– Automated regression testing
– Continuous integration (CI)
– Continuous deployment (CD)
– Canary tests
– Split (A/B) tests
•
Operations-friendly features:
– Feature toggles
– Feature-level access control
– Built-in monitoring
– Self testing
– Self recovery

A Better View: Agile Delivery + Operations
•
Multi-modal approach to
software development
•
Operations activities are also
streamlined and “leaned out”
•
Some teams will adopt a “you
build it, you run it”
philosophy, but a common
operational infrastructure still
required

DevOps Changes Your Relationship with the Business
•
•
Your business and IT processes must be integrated
– Plans must be high-level with the details coming just in time (JIT)
– Emphasize delivery of value via a consumable solution rather than
transitory work products of questionable value
– Schedules and estimates must be given in ranges
– Traditional business approaches will eliminate most benefits of
agile/DevOps
The new relationship with the business:
– They must be actively involved with development all the way through the
lifecycle
– The greater visibility and control that they now have implies the need for
greater accountability on their part
– They often don’t understand the implications of what they ask for, you
need to educate them
– You need to demonstrate that disciplined agile delivery is not cowboy
programming. It is very likely far more disciplined than their current
processes

DevOps Critical Success Factors
1. Build a collaborative and respectful culture
across your entire IT organization
2. Focus on people, but don’t forget process and
tooling
3. Choice is good

Parting Thoughts
•
You don’t just do DevOps
– You must also have the DevOps mindset
•
DevOps improves IT’s ability to support the rest of the
organization
– The rest of the business needs to evolve too
•
You have to build DevOps for yourself
– You cannot buy it
•
DevOps permeates IT
– You don’t have a “DevOps Group”, nor “DevOps
Engineers”
