What is DevOps and How does DevOps Work?


- Advertisment -

DevOps- It is one of the most heard buzz words in the tech industry nowadays. People are searching about DevOps on the internet like- What is DevOps? How to be a DevOps engineer? or scope of DevOps. Well if you also this kind of questions, then you’ve come to the right place.

In this article, we will tell you every important information about DevOps but first, let us understand what DevOps is?

What is DevOps

While researching DevOps on the internet, I’ve found many definitions of DevOps on the internet and to be honest, those definitions were quite difficult to understand for a beginner. So we will tell you what is DevOps in the easiest possible way.

But first, we need to understand that DevOps is neither a tool nor a programming language, then what exactly is DevOps.

DevOps is made of two words- the Development and the operations. When an application is developed, usually there are two teams- the developers that write codes, design and test new features and the other team is the operations team that has the role to manage all the servers and look after their security and backups.

Whenever the developer team develops a new app or a new update, they send it to the operations team and operations team to review the updates and diagnose any error caused by the change. Due to this, the operations team sometimes feels that the developers have tossed their work to the operations team. So to solve this problem, DevOps comes into play.

In the DevOps, the developer’s team and the operations team work together. They discuss everything and sometimes change to rules and responsibilities. This mindset where everybody works together is DevOps.

To do things more productively, DevOps introduces the concept of automation. From testing new codes to how infrastructure is provisioned, they try to automate everything.

Apart from automation, the DevOps team also writes code in small pieces rather than in big blocks. Writing small pieces of code allows them to increase the frequency of deployment and improve the time to deploy new code whereas a big block of code takes week or months of testing.

This allows developers and the operations team to have more time in understanding the performance of the update they’ve implemented on the application or the service. The main goal is to have a team that gives its customers a great experience.

DevOps is a mindset that integrates developers and operations teams in order to improve productivity by automating most of the things and continuously measuring application performance.

How DevOps came to World Market

First, we have the Waterfall model. Developers developed this model had the idea that software is going to be stable for many years to come. Well over time, people thought that this model was very slow and it takes a long time for the developers to develop the software. Most of the time when the software was developed, the requirement of the customers would change.

So due to this, the agile development model comes into play. The major difference between agile and waterfall is that in agile, the entire software would not be delivered at one time. But it will be broken down into smaller chunks of features and delivered and every two or three weeks, new features would be added in the application. This model led the developers to add features according to the user using feedbacks. Even though the agile model has reduced the development time drastically, it lacked in the co-operation between the developers’ team and the operations team.

Well, this is where DevOps came into play by bringing both the developers and the operations team together. It

DevOps Lifecycle

I’ve told you about DevOps above but you cannot understand DevOps without understanding the DevOps lifecycle. The DevOps life cycle includes seven phases mentioned below-

  1. Continuous Development
  2. Continuous Integration
  3. Continuous Testing
  4. Continuous monitoring
  5. Continuous Feedback
  6. Continuous Deployment
  7. Continuous Operations

Let’s discuss the seven phases of a DevOps life cycle.

1) Continuous Development-

In this phase, a company plans the objectives that they want to deliver to the customer. Once a company is sure about the objectives, they start the development of the project. It includes activities like coding and testing and then putting it to the next phase

2) Continuous Integration

This process starts automatically after development. It includes steps like planning for the next phase, understands the code to generate the desired outcome. It is a seamless process that us to the next phase.

3) Continuous Testing

The Testing process gives information about different aspects of applications. It checks the actual use of the application while ensuring that it can still have its use in the live environment.

4) Continuous Monitoring

In this phase, usage of the application is recorded and processed to identify the problem areas of an application. This phase improves the efficiency of the software.

5) Continuous Feedback

During continuous monitoring, the efficiency of an application is improved. Continuous feedback is an important phase where a customer gives feedback which helps the company to improve the working of a software.

6) Continuous Deployment

This phase ensures that the code is deployed in software with maximum accuracy.

7) Continuous Operations

All DevOps operations are based on continuity with complete automation in the processes. The Continuous phase is very important as it removes the abundant steps that may distract the developers. It accelerates the overall time in the development of the software.


DevOps is becoming mainstream in the software development industry. Nowadays, every company want to explore DevOps because It has so many advantages and some of them are listed below-

Teamwork– DevOps has started a new culture in the field of software development. People from the developers’ team and the operations team work together to innovate and experiment more effectively which leads to the development of the product.

Speed– The DevOps business model enables developers and operations teams to the changes in the market and grows more effectively. It enables a company to innovate faster for their customers.

Rapid Delivery of Product– With the increased frequency of speed, a company can innovate and improve their products faster. The quicker a company releases new features and fix bugs, the more they have the advantage over their competitor.

Security- You can adopt DevOps without risking security by using automated policies and configuration management techniques.

Trust– DevOps business model ensures the quality of application updates infrastructure changes. This helps a company maintaining a positive experience for the user.

Scalability– Automation, and Consistency help you manage complex systems more efficiently with reduced risks.

As more and more companies are adopting DevOps, people who have knowledge about DevOps are in high demand. We will talk about the scope of DevOps from two perspectives-

1)Scope of DevOps within an organization

2) Scope of DevOps as a career

Scope of DevOps within an organization

DevOps integrates developers and the operations team because it helps the organization to release its product/service to their customer fast without harming the quality standards. In

This can be achieved by automating the whole system. By automating, you build fast, deploy fast, test fast, fail fast and improve fast. This improves the reduction of failure as you are continuously building, deploying and testing your code in an automated way.

Scope of DevOps as a career

To be a professional DevOps engineer, you need to have knowledge about various things like-

  • 1)Build Automation
  • 2)Configuration Automation
  • 3) Cloud Ops/SysOps
  • 4) Monitoring/Logging/Reporting/Support
  • 5) Release Management
