What is DevOps?

The term itself is quite self-explanatory. DevOps is a compound from ‘development and operations’. Rather than a profession, DevOps is a methodology aimed at improving the quality of software. It is a culture that promotes agile relations.

The DevOps movement began in 2008 when software development and operations communities became concerned about how IT companies delivered software. Developers believed that if they could run their code in a local environment, production would also be the case. After that, the Operations team tried to deploy the code. Something went wrong, and they blamed Developers and expected them to fix it.

No wonder this approach delayed product releases. The quality of the final product often suffered. A lot of changes were released at a time, so it was tough to understand what exactly caused issues in production.

DevOps emerged as a solution to this problem. This bridge between Development and Operations helped to improve collaboration and communication. Aligned Development and Operations’ objectives contributed to more efficient and faster delivery processes. 

Who is a DevOps Engineer?

A DevOps Engineer is an IT professional who brings the DevOps methodology to life. DevOps Engineers manage the development and administration departments. 

Currently, the DevOps Engineer role is still evolving. They are either developers who became interested in administration or system administrators who revealed a passion for scripting and coding. In every case, DevOps roles are cross-functional, which presupposes in-depth knowledge and hands-on experience. A DevOps Engineer is somebody who sees the bigger picture and plans infrastructure by juggling between coding and testing, overseeing and facilitating code deployments.
 

What Does a DevOps Engineer Do?
