What is DevOps ?

Dev-ops is nothing but a type of cultural philosophies, framework, methodologies and certain practices by using the tools to improve the organizations / Company’s ability to deliver the product or software or services at high speed within efficient time. By using devops methodologies companies can be able to evolve and improving products at a faster pace than organizations using traditional software development and infrastructure management processes. “Dev” and “Ops” refers to replacing siloed Development and Operations to create multidisciplinary teams so that they can work together with shared and tools by efficient making practices. Occasionally, these are the two teams are merged into a single team where they can work together across the entire application.

 

The Role of Software developer’s vs IT operations team In Traditional software development

SOFTWARE DEVELOPERS

-> Software developers usually develop the product code / Software applications.

-> They are responsible for implementing the additional or required features in the product / Software applications by collaborating with other development teams.

-> Once the code is ready or implementation of code is ready then they will pass on code to operations team by maintaining the source code repositories with the help

of the version control systems.

IT OPERATIONS TEAM

-> It operations team plan the provide the required Infrastructure for the Testing the Applications and Production of the applications as well.

-> Maintaining the Databases.

-> Deploying the Applications.

-> Monitor the Application performance and validating them by taking the required actions.

 

Why DevOps?

Automation helps companies achieve speed, quality, and efficiency throughout the software development lifecycle is critical. Then devops comes into the picture.

 

DevOps Philosophy?

DevOps is about removing the barriers between two traditionally separate team like development and operations. In some companies, there may not even be separate development and operations teams’ engineers may do both.

In DevOps, the two teams work together to optimize both developer productivity and operational reliability. They strive to communicate frequently, increase efficiency and improve the quality of the services or product / Software they provide to customers. Quality assurance and security teams may also be closely integrated with these teams.Companies that use a DevOps model, regardless of their organizational structure, have teams that consider the entire development and infrastructure lifecycle as part of their responsibility.

 

Working principle of a DevOps :

From design and development to test automation and from continuous integration to continuous delivery, the team works together to achieve the goal. Employees with both development and operational skills work together and use various CI-CD tools and monitoring tools to respond quickly to  resolve problems and errors and customer requests as well. These teams are using practices to automate processes that were manual and slow in the past. They use a technology stack and tools that enable them to run and develop applications quickly and reliably.

These tools also help engineers to complete tasks themselves by deploying code or providing infrastructure that would normally have required the help of other teams, further increasing the speed of a team.

 

Devops practices :

Instead of using traditional software development practices, DevOps practices such as continuous integration and continuous delivery solve these problems and enable organizations to deliver quickly and in a secure and reliable manner. Infrastructure automation practices, such as infrastructure as code and configuration management, help keep computing resources elastic and responsive to frequent changes. In addition, the use of monitoring and logging helps engineers track the performance of applications and infrastructure so they can respond quickly to problems.

 

What does the devops Engineers do?

-> Automating and streamlining the software development and infrastructure management processes.

-> Managing physical and virtual servers and their configurations.

-> Monitoring IT infrastructure’s state and the application’s performance and its validation.

 

Devops Tools?

No one tool, and no single vendor, can provide all the capabilities needed to support a DevOps practice or their pipeline. But there are some key areas to consider when choosing tools and products for your organization’s needs and specific DevOps goals. Everyone needs various DevOps tools like Puppet, Jenkins, GIT, Chef, Docker, Selenium, Azure/AWS etc to achieve automation at various stages, which helps in achieving Continuous Development, Continuous Integration, Continuous Testing, Continuous Deployment, Continuous Monitoring to deliver a quality software.
