DevOps is a culture that improves collaboration between development and operations teams. It aims to speed up delivery of software and services according to business needs through automation. The three pillars of DevOps are infrastructure automation, continuous delivery, and reliability engineering. Automation improves productivity, reliability, and standardizes processes. This allows for faster, more cost effective and higher quality software delivery that better meets customer needs. DevOps builds trust between teams and increases business revenue through quicker feedback and turnaround.

Challenges with current Business model
 Everything needs software nowadays.
 Software has to run on a server to become a service.
 Delivering a service from inception to its users is too slow and error- prone.
 There are internal friction points that make this the case.
 This loses you money. (delay = loss) IT is frequently the bottleneck in the transition of “concept
to cash.”

7. Introduction to DevOps
Why ? Reason !
 Defects are released into production, causing outages.
 Inability to diagnose production issues quickly.
 Problems appear in some environments only.
 Blame shifting/finger pointing.
 Long delays while dev, QA, or another team waits on resource or response from other teams.
“Manual error” is a commonly cited root cause. Releases slip/fail. Quality of life issues in IT.
