7. What is immutable infrastructure?
Microsoft Ignite 2016
5/19/2018 4:32 PM
What is immutable infrastructure?
Completely eliminates infrastructure config drift
Everytime a new "build" is promoted to release, build an entirely new "stack", then tear down the old "stack"
Removes the need to maintain separate UAT/Staging environments, in effect, the UAT/Staging environment becomes production*

Branching strategy
Depending on branching strategy, consider multiple CI pipelines for different branches.
Can automate the creation of new CI pipeline (See demo later  )

Unit Tests
Add from the beginning.
Consider as part of ‘done’ criteria
Run as ‘first’ step in CI test process ‘fail fast’.
Do not ‘add excessively’ to attempt to get 100% code coverage.
Legacy code, highly coupled Harder to retrofit

Integration tests
Typically cover more code
Viewed as adding more value overall
Slower – run as secondary step in CI test process
For legacy/tightly coupled code:
Begin by abstracting data access
Integration tests can start at top most layer, hit abstract data layer

Functional / UI tests
Typically longest to run and most brittle
- Selenium grid in the cloud for UI tests
- Selenium cloud testing
Often run daily to reduce pipeline execution time rather than every check-in
Consider not running in Dev environment – ensure fast Build turn-around, run in QA env

Infrastructure Code/Promotion Workflow (for enterprises)
A modified version of github flow meant for enterprises who need to segregate dev and prod environments
PR early – not at the end of your work!
PRs will act as gates for changes to flow through environments
Introduce branches in the middle as more environments are required (adds overhead)
