DevOps (development and operations) is a collection of tools and technologies combined to carry out various business processes. It aims to bridge the gap between two of the most significant departments in any IT organization, the development department and the operations department. This blog will help you get an overview of the numerous concepts that play a significant role in defining DevOps.
History of DevOps
Before DevOps came into the limelight, our traditional ol’ IT had two separate teams in an organization – the Development team and the Operations team.
The development team worked on the software, developing it and making sure that the code worked perfectly. After hours of hardwork and a lot of trial and error, the team releases a code which has to be executed by the Operations team which is responsible for the release and operation of the code.
The operations team will be checking the application and its performance and reporting back any bugs, if present.
As simple and planned out as it may sound, the two major teams always had a conflict when it came to execution.
For instance, let us say, the development team developed a code using an i7 processor, 8GB RAM, OS as Ubuntu, and php 5.6 scripting language, where as the Operations team ran the same code using i5 processor, 16GB RAM, OS as Centos and php 7.0 programming language.
When the operations team ran the same code, it wouldn’t work.

The reason for this could be the difference in the system environment or any missing software library.
The operations team flagged this code as faulty, even though the problem could exist in their own system. This resulted in a lot of back and forth between the Developers and the Operations team.
To bridge this gap, Development(‘Dev’) team and Operations (‘Ops’) team collaborated giving rise to DevOps.
For example, to solve the above problem, the Development team encapsulated their code in a container which is a lightweight software environment.
This software environment had all the required software encapsulated in it, which the code or the application will require to run as expected.
When the developers were done with their work, they would simply pass on this container along with the code to the operations team. The Ops will run this container, along with the code, and it worked as expected!
