by Cyfinity Global OUR GLOBAL CAMPUSES OUR CENTRES WORLDWIDE

DevOps is defined, as the efficient development, testing, deployment, and operation of the highest quality software possible. Software developer works closely with DevOps.


DevOps

DevOps or Developers and Operations is a methodology or a procedure to use various tools for solving problems that are face between Developers and Operations. It is not a tool or team. DevOps help in the smooth working of the development process from the development phase to the final deployment and maintenance. DevOps professionals are solving the problems a software engineer faces in the development procedure.


Life Cycle

DevOps is not a single-step journey but formed by several steps and stages.

Let me detail the various stages involved in DevOps:

  1. Continuous Development: The first step in building any software is to have an idea and make a plan accordingly. DevOps follows a continued development approach in which corporates connect via Git (version control system), which is used by almost all the companies and organizations working in IT. The source code is shared via Git so that everyone can perform their tasks individually and push the code on completion and demand. 

  2. Continuous Testing: Testing is one of the vital steps in the development process. Once the source code is put over Git, it undergoes testing phases. With changes added in the source code, testing is done for the changes made so far. It is a continuous testing process.

  3.  Continuous Integration: With the completion of one stage in DevOps, integration tools come into the picture. 

  4. Continuous Deployment: Addition features with continued development may incur modifications in the application environment. It is done with the help of deployment tools. This process of modifying the application environment with additional features is called continuous deployment. 

  5. Continuous Monitoring: Bugs has no limitation. You can witness bugs in your software even after extensive planning and testing. So, to prevent any bug hindering the development process with continued monitoring is required. Various monitoring tools keep checking on these bugs or any malicious activity in the application environment.

  6. Git: Git is a version control system, which is used by almost all the IT sector corporate. It is free and open-source, and taking projects from small scale to large scale can be worked out on this.

  7. Docker: Docker is another tool used extensively, which makes distribution possible using containers and automates application deployment. Applications built over docker are OS and platform-independent.

  8. Selenium: This is one of the testing frameworks for web application development used by most companies to perform testing. It is also an open-source tool and can work on various platforms like Java, Python, Ruby on Rails, and so on.

  9. Maven: Maven is a guiding tool, compiles source code, run test cases, packages the results in JARs, and upload. 

  10. Jenkins: Jenkins is responsible for finding and killing the bugs.

  11. Nagios: It is a free and open-source tool that fixes the problem in IT infrastructure.

  12. Ansible: It is a simple tool with large productivity gains.

  13. Puppet: It provides open-source tools for some minor projects.


Job Opportunities

With the increased technological advancements, job opportunities in DevOps are rising each day. According to the study, 4000+ jobs are available in India only. It is seen DevOps engineers are the highest-paid employees in the IT sector. Various job roles include DevOps Engineer, DevOps Architect, DevOps Consultant, and many more.


Wrapping Up 

I hope this is enough to get a beginner insight into DevOps. There are several opportunities both in career and jobs for DevOps practitioners. It is not a one-step process but extensively monitored at different levels for efficient building and development of the software. DevOps helps system engineers in preventing the bugs that may disrupt in the middle of the development of the software.
