Beginner’s Guide to DevOps: What You Need to Know

Updated: Jun 11

In today's fast-paced technological landscape, the traditional methods of software development and delivery are often too slow and cumbersome to keep up with the demands of modern businesses. The ever-increasing need for rapid deployment, continuous updates, and resilient applications has led to the evolution of software development practices. One of the most significant advancements in this area is the adoption of DevOps—a set of practices that combine software development (Dev) and IT operations (Ops) to shorten the development lifecycle and provide continuous delivery with high software quality. 


What is DevOps?


DevOps is basically a software development strategy that bridges the gap between the development team and the operations team. DevOps is a term for a group of concepts that not all new half catalyze into a movement and rapidly spread throughout the technical community. It is a practice of operations and development engineers participating together in the entire software life cycle from design through the development process to production support. 


DevOps is not a technology, It is a methodology. 


Thus, it is a practice that is dedicated to the study of building, evolving, and operating rapidly changing systems at scale.



Why DevOps 


Traditionally, instead of DevOps Methodology, there was a Waterfall model and Agile methodology. 


Waterfall model


The waterfall model is a project management methodology based on a sequential design process. It finishes one phase before another phase can begin. It is developed as a software development lifecycle model. It lends itself to projects that are small in size and whose requirements can be determined upfront. A simple waterfall mode has 6 phases :- Requirement, Design, Implementation, Verification, Deployment, and Maintenance. But it isn't suitable for all projects. 


Limitations of the Waterfall Model


  • High amounts of risk and uncertainty. 

  • It is not a good model for complex and object-oriented projects.

  • Not suitable for projects where requirements are at a moderate to high risk of changing. 

  • No working software is produced until late during the life cycle.

  • Once an application is in the testing stage, it is very difficult to go back and change something that was not well thought out in the concept stage.



Agile methodology


It is a software development methodology that promotes shorter development life cycles and where there is a feedback loop that prioritizes the customer feedback and changes that need to be made according to it. It is a full spiral process. 


Limitations of Agile Methodologies


  • Agile methodology is a sprint-based working, so if any changes occur, it can be cleared only after the sprint period which may take much time.

  • There are a lot of conflicts between the development team and the operations team of the company because the deployment is not properly done.

  • Inconsistency in computing environment.

  • Agile methodology made the deaf part of the company (that is unresponsive, resistant to change, or not effectively communicating and collaborating) pretty agile but on the off side of the company they needed some solution in order to solve the problem.

  • Manual deployment



So, to discard all these limitations of agile methodology and waterfall model the only solution is DevOps.

Impact of DevOps


DevOps is a culture that emphasizes cooperation between Dev & Ops Teams and automation of the whole process. A lot of companies like Amazon, Walmart, Sony Pictures, Netflix, Ola, Grofers, Adobe, Flipkart, etc… all these big enterprises are using DevOps to automate all of their processes, increase the collaboration between the developers and the other teams, etc. Once a company starts using DevOps the whole quality of the product increases and also the whole cost efficiency also increases by making the product more efficient and making more profits.
