DEVOPS in Software Development

Let’s starts with a question who is a DevOps engineer?

Lot of people have a confusion whether a DevOps engineer is developer or is he an admin or a tester or is he responsible for the life cycle of a software application. i will clear  all your doubts through this article.

What is DevOps:

 

DevOps is the practice of operations and development engineers that work together in the entire project lifecycle, from the design and development process to product releases and support. DevOps helps to reduce time taken for the software development life cycle.

Who is a DevOps Engineer?

A DevOps engineer introduces processes, tools, and methodologies to balance the  needs throughout the software development life cycle, from coding and deployment, to maintenance and updates

 

Why we need DevOps?

Software development have two major departments one is development team another one is operational team.

Development team design, program and built a software from scratch, operational team perform testing and deploy the software to the customer.in the mean time development team is idle, If the operational team find any bugs they gave feedback and report to the development team, then the development team works on the bug   forward the progress to the operational team they will do the testing again then they will deploy the software to the client.

In some cases the development team will commit themselves in new projects before operational team performs their tasks. If the operation team find any bugs they report the bug to the development team , but they are commit in new projects so they need to wait for the development to clear the bug .it makes delay in the deployment of the software .

DevOps solves these issues through its approach,

In DevOps approach both team came together and work in collaboration with each other. DevOps symbol resembles infinity sign suggesting it is continuous approach and works on the improvement of the efficiency .it make the team deliver quickly and the deployment are continuous and smooth. There may be obstacles in communication between both team, DevOps manages streamline flow between team and makes the software development successful. 

Before DevOps, software applications were developed with either the waterfall model or the AGILE development model:

1. Waterfall or sequential model was a pioneering approach in the Software Development Life Cycle (SDLC). With this model, software development becomes a linear process where different phases and tasks are positioned successively.

2.AGILE software development, on the other hand, involved the use of various approaches and the collaboration of multiple teams in SDLC.

The linearity of the waterfall model and the cross-functionality of AGILE software development were still unable to ensure quick and continuous delivery of flawless software applications. 

DevOps services came into play by effectively serving the purpose of reducing the time involved in SDLC for prompt deliveries and securing the continuous production of high-quality software applications.

DevOps lifecycle:

Plan – In DevOps planning plays an important role. In this stage, all the requirements of the project and everything regarding the project like time for each stage, cost. etc are discussed. This will help everyone in teams to get a brief idea about the project. 

Code – In this Stage the code is written over here according to the client’s requirements. Here the code is divided into small codes called Units. This is done to get a clear picture of the code. 

Build – In this stage Building of the units is done.

Test – Testing of all units is done in this stage. So we will get to know where exactly the code is having bugs and if there are mistakes found it is returned.

Integrate – In this stage, all the units of the codes are integrated. That means in this step we will be creating a connection between the development team and the operation team to implement Continuous Integration and Continuous Deployment.

Deploy – In this stage, the code is deployed on the client’s environment.

Operate – Operations are performed on the code if required.

Monitor – In this stage monitoring of the application is done over here in the client’s environment.

Tools used in DevOps:

Planning tools- Git, Jira

Coding tools- python, java, c++ ,GitHub, GitLab

Software build tools- Docker, Puppet, Chef, Ansible, Gradle.

Testing tools- Vagrant, Selenium, JUnit, Codeception, BlazeMeter, TestNG

Deployment tools – Jenkins, Kubernetes, Docker, OpenShift, OpenStack, Jira.

Monitoring tools- Nagios, Splunk, Slack, New Relic, Datadog, Wireshark.

 

By implementing DevOps in your organization will ensure, faster deployment, increases the unity of the team , simplifies the development process , more concentration on the customers requirements, work is more smarter and faster than the traditional ways. DevOps also manages the unplanned work in a better way. increases the collaboration and trust between the workers.

 

Conclusion:

If you don’t implement DevOps in your organization yet, you must seriously consider adopting its practices. Despite any reasons that might be holding you back, the advantages of DevOps are just too big to ignore.

DevOps is Not a goal But a Never Ending Process Of

 Continuous Improvement .
