DevOps is a set of practices and cultural philosophies used in the software development and deployment lifecycle. It aims to improve collaboration between development (Dev) and IT operations (Ops) teams.
To implement DevOps effectively, a variety of tools and technologies are used to automate and streamline various aspects of the software development and deployment lifecycle.
I remember from my previous job stint…
Just a couple of days before the project patch release, the DevOps pipeline failed…
And everything stopped.
Every developer working on the project is immobilized.
Development halted.
No one can do anything until the pipeline gets fixed.
Which results delay in software release…
Put a dent over customer expectations from the company…
Just a small blunder in the DevOps pipeline and it Incurred a colossal cost to the company…
That’s why, to mitigate these consequences, companies are willing to spend gazillions of dollars…
Today DevOps market value stands 💲10.4 billion and expects to hit 💲24.71 billion in 2027…
In this ever-evolving tech world… If you want to secure your job, you cannot afford to miss this trend.
