Development and Operation Cycle

Heart of DevOps
Collaboration between Development and Operations

Autonomous teams

Teams are diverse
Self sufficient teams
Teams have members who specialized in:
Product Engineering
Operations
Data Engineering, etc.

Shared responsibilities

Autonomous teams take care of specific parts of the software
They are responsible for developing and running
You build it, you run it

Automation

CI/CD pipelines helps automate change management, testing, and deployment
Automation is a time-saver
Developers focus on creativity, not the simple tasks
Without CI/CD pipelines, testing and deployment must be done manually

Post-mortem

All software is prone to errors

Something can always go wrong

When a software problem is identified:

First solve it
Then review what went wrong

This review is called Post-Mortem

No one is blamed in the Post-Mortem
