All you need to know about DevOps is it is not a single technology. It is the set standard culture and practices wherein a cross-functional mode of working comes into the picture. A single team is addressed as DevOps engineers and are held responsible for end-to-end activity in the software development process from the initial phase to change as per the feedback of the end user. The team comprises of system admins, quality analysts, developers, and the testers.
Just by the term, one may think what DevOps is all about? And what ‘O’ in caps doing there? Well, we may not find a straight answer for this. Rationally speaking, we may not be able to answer this question in a technical or philosophical manner.
Let us understand the DevOps terminology.
[Literal meaning: Development+Operations, truncated =DevOps]
DevOps is the culture and practices set for integrating the developers’ and the operations’ team so as to enhance the productivity and collaboration.
The DevOps culture is to have a single group of engineers comprising the system admins, developers, quality analysts, and, the testers. They hold the end-to-end responsibility of the software development starting from the initiation, requirement gathering, test, infrastructure, deploy an application, monitor, and implement changes as per the end users feedback.
Gartner defines DevOps as a change in IT culture, focusing on rapid IT service delivery through the adoption of agile, lean practices in the context of a system-oriented approach. DevOps emphasizes people (and culture) and seeks to improve collaboration between operations and development teams. DevOps implementations utilize technology — especially automation tools that can leverage an increasingly programmable and dynamic infrastructure from a life cycle perspective.
The main motto to implement DevOps culture is time reduction and productivity enhancement wherein the changes to a system during the software development is made simultaneously coupled with quality assurance.
Prior to DevOps culture, waterfall methodology was followed and there were several challenges that consumed a larger amount of time. Whereas, this DevOps methodology brings in the cross-functional mode of working by collating the waterfall and agile methodology.
Waterfall method is often quoted as rigid and inflexible. Some of the challenges faced in waterfall methodology include:
Agile development is used as an umbrella term for software development methodologies including kanban, lean development and extreme programming, scaled agile framework, and scrum.
DevOps seems to be rising the standards of the team and work success. One main reason is that, rather than using a single tool, it uses a toolset or toolchain.

In the DevOps culture, the single group engineers meet before initiating a project. The bigger team comprising of developers, testers, operations, and support professionals chalk out a plan for creating and deploying the software.
Further, as the developers write codes, they are deployed every day with automated testing. Once the code gets through all of the testing methods, it gets deployed to a select number of users [a small number]. It is monitored for unforeseen problems and stability. As it reaches the stability, the new code is distributed to almost all the users.
The appreciable part of this scenario is all these are automated processes and there is no human intervention.

Continuous Delivery-> Continuous Testing-> Continuous Integration-> Continuous Monitoring-> Continuous feedback and optimization
As you know the benefits now, the next immediate question for an aspirant is how to learn this methodology.

DevOps culture is nothing but a happy balance between the developers and the operations team. It is exciting as you integrate technology and solve challenges. It is understood that the developers who are unable to monitor and the administrator who cannot develop may become less valuable for an organization in the long run.
Whether you learn DevOps or not, the motto or the culture behind it is of universal acceptance.
Every specific pain point in an organization has to be considered that calls for a soft skill or technical enhancement. It should accommodate the existing process with an upliftment.
