The terms “development” and “operations” are combined to form the phrase “DevOps,” which stands for “development and operations.” The method known as “DevOps” enables a single team to handle the whole of the application development life cycle, including “development,” “testing,” “deployment,” and “monitoring.”
DevOps’s end aim is to shorten the time it takes to build a system while simultaneously providing new features, bug fixes, and software upgrades (https://www.lifewire.com/what-is-a-software-update-vs-software-upgrade-)) more often and in tighter sync with business goals. With the support of the DevOps software development methodology, you can create software of the highest possible quality much more rapidly and with a higher degree of dependability.
The Beginnings of DevOps
Before we started using DevOps, we used two different methods for developing software: the Waterfall method and the Agile method.
Waterfall Model
A software development paradigm that is relatively easy to understand and linear is known as the waterfall model. A bottom-up methodology is used to develop this model. This approach requires a variety of prerequisites, beginning with the collection and analysis of data.
The following step is called the Design phase, and during this phase, you will create a plan for the program. In this step, you consider what the finished product of the program will look like. When the design is finished, you move on to the Implementation phase, when you start writing code for the program. This phase continues until the design is finished. The application’s many components are being worked on collaboratively by the developers.
In the Verification phase, which comes after the Application Development phase, you will test the application after it is finished being developed.

When all of the application’s tests have been successfully performed, the application is then deployed into the production servers.
The Waterfall Model’s Benefits Include Being Easy to Understand and Put Into Practice
- Streamlines the testing and examination process.
- It helps to economize a significant quantity of both time and money
- This method is suitable for smaller projects if all criteria are properly established.
- Enables departmentalization as well as supervision at the management level
Agile Methodology
The software development process is divided into many different iterations or sprints when using the agile methodology, an iterative-based software development technique. Each iteration follows a process that is similar to that of the waterfall model and includes stages such as “Requirements Gathering,” “Design,” “Development,” “Testing,” and “Maintenance.” In most cases, the period of each cycle ranges from two weeks to eight weeks.
Agile Process
During the first iteration of an Agile project, a firm will release the application with a few of the highest priority features. After the program has been made publicly available, end-users and customers will provide feedback about the software’s functionality.
After implementing the required adjustments and adding new features, the program is published again, marking the start of the second iteration. The whole of this process is repeated until the program meets the quality standards that have been set.
The Benefits of Using an Agile Model
- It reacts positively and adaptively to changes in requirements.
- Errors fixed early on in development result in a more cost-effective approach overall.
- It enhances the product’s quality while also enhancing its error resistance.
- Free
- Allows communication amongst those participating in the software project to occur directly.
- Extremely well-suited for large-scale and extended-term projects
- Incredibly few resources are needed, and it’s very simple to administer.
The Various Stages and Tools of DevOps
Continuous development, integration, testing, deployment, and monitoring comprise the DevOps Life cycle. Now that we have that out of the way let’s look at each step of the DevOps lifecycle individually.
Ongoing Process of Development
This is the part of the development process referred to as “planning” and “coding” of the program. During planning, you make decisions on the project’s overall direction, and developers start working on the application’s code.
It is not necessary to automate devops tools to plan. However, quite a few tools are available to keep the code maintained. It doesn’t matter what language the code is written in; to maintain it, you’ll need to use tools for version control. The management of the code in this manner is referred to as the Source Code Management procedure.
Integration That Is Constantly Done
The flow of the Process:
This stage is the most important part of the DevOps lifecycle. It is a process in which the programmers are mandated to make more frequent commits to their modifications to the source code. Depending on your preferences, this might occur once a day or once a week.
