DevOps

DevOps is basically a combination of two words- Development and Operations. DevOps is a culture that implements the technology in order to promote collaboration between the developer team and the operations team to deploy code to production faster in an automated and repeatable way.

Why DevOps?

The goal of DevOps is to increase an organization’s speed when it comes to delivering applications and services. Many companies have successfully implemented DevOps to enhance their user experience including Amazon, Netflix, etc.

How DevOps is different from Traditional IT?

Traditional IT has 1000s lines of code and is created by different teams with different standards whereas DevOps is created by one team with intimate knowledge of the product. Traditional IT is complex to understand and DevOps is easily understandable.
