The IT industry has gone through a major revolution within the last decade. The project execution model has changed a lot.


Waterfall Model


In this model – there were almost constant requirements and was like a fixed bid project to be delivered at agreed-upon timelines. IT managers used to plan around people, processes, and technologies and communicate to customers.


Typically, in this model – there were six major phases in this cycle:


Requirement Gathering -> Design -> Coding & Unit Testing -> System & Integration Testing -> Production Deployment -> Post Production Support


Agile Model


The Waterfall model had its own advantages, but it had major drawbacks. Requirements used to get reviewed and finalized at the beginning of the software development lifecycle – so it turned out to be a cat when the dog was expected. It led to client dissatisfaction.


Agile solved this problem by introducing shorter release cycles in the form of program increments and sprints. It had requirement gathering, design, coding & unit testing, and system testing in each sprint. Sprint demo to customer also solved the dog turning cat in the end. However, integration and Production deployment in the end led to many conflicts between the development & Operations teams and also issues in production release.



DevOps Model


DevOps resolved issues by having developers, testers, and operations teams sitting together. DevOps can be understood as – an extension of Agile by maturing the deliverables ready to be deployed in production after every PI or sprint. All infrastructural planning and issues are completed during the execution only. Infrastructure configuration overheads add a great pain during the production deployment.


DevOps has brought different skilled people together and ensured that each sprint has some deliverable to be deployed in Production after a specific interval. It's like a pipeline that can deliver the functionality every day, every hour, or even every minute.
