DevOps Definition | What is DevOps

Learn what exactly DevOps is, what is the DevOps life cycle, different stages of DevOps, and various use cases of DevOps.

What is DevOps?

DevOps is a collection of methods, technologies, and a mindset that automates and integrates application development and IT teams’ processes. You must emphasize team engagement, cross-team coordination, collaboration, and technological automation. 

What is the DevOps life cycle?

The DevOps Lifecycle is a collection of phrases that DevOps uses to involve development and operations teams to deliver software faster. Code, build, test, release, deploy, operate, show, and plan are positive DevOps approaches.

Non-stop development, non-stop integration, non-stop testing, non-stop monitoring, and non-stop feedback are all part of the DevOps lifecycle. Each piece of the DevOps lifecycle required some equipment and applied sciences to acquire the procedure.

Different stages of DevOps

Phase 1: Planning

The planning stage of a DevOps pipeline comprises everything that happens before developers start writing code and are roughly analogous to the requirements-gathering step in traditional software development.

The DevOps approach to planning is distinguished by a strong focus on the demands and experiences of customers. All stakeholders’ feedback is incorporated into the planning process, and product and project managers and developers work together. 

Phase 2: Development

The planning and coding phases of DevOps overlap and inform one another. Small modules are built-in by DevOps practitioners, who rely on automated technologies to maintain version control, enforce consistent style standards, and protect against security risks.

Software testing is a separate phase in traditional development settings, done by quality assurance (QA) teams when both individual components and the overall program are complete. Instead, the DevOps model incorporates automated testing into all stages of software development. “Shift left” refers to the practice of developers running their own QA scripts early in the build process.

Phase 3: Continuous integration

The DevOps technique relies heavily on continuous integration (CI). It entails regularly merging new code created by various developers into a single, centralized repository. Regularly, at least once a day, each team member’s contributions are integrated into the main branch of the source code. Automated tools are utilized to download the code, prepare the build, and test it before sending it to the proper staging environment or repository.

Phase 4: Deployment

Continuous integration (CI) is for the central code repository, whereas continuous delivery (CD) is for the end-user-facing production environment. According to the DevOps process, new features, upgrades, and other modifications to the program should be released into production.

DevOps practitioners use automated provisioning solutions to manage and monitor test and production environments (a concept known as infrastructure as code). They can be sure they’re testing the software in situations exactly like the production environment and that what works in testing will work in production.

The code is ready for deployment once it passes this automated testing. On the other hand, DevOps approaches rely on automated technologies to carry out this deployment.

Phase 5: Operations

When DevOps software goes live in production, the operations team will use automated tools for configuration management, scaling, and load balancing.

Phase 6: Learning

A DevOps organization will use automated solutions to solicit and gather customer feedback on their experiences and capture metrics indicating the software’s performance. This data will guide the DevOps team’s future efforts to improve the app, and it’s a significant factor in the pipeline’s planning stage.

These stages take place in a collaborative setting that encourages experimentation and invention. Automated software development toolchains, code exchange platforms, and collaboration solutions enable all of this. Many of these technologies are free to source and were developed in the context of DevOps.

Use cases of DevOps 

1. Online financial trading firm

The financial trading company automated the testing, developing, and development of methodologies. Deployment was completed in 45 seconds with the support of DevOps. 

2. Automotive industry application

Employees may assist automobile manufacturers by using DevOps to detect any errors in production scalability. 

3. Airline industry advantages

With a continuous testing standard, United Airlines has saved about $500,000. It has also enhanced its code coverage by 85 percent, compared to previously, thanks to DevOps.

4. DevOps bug reduction

Bugs have decreased by about 35% after the use of DevOps. Thanks to this, Rabobank provided better quality apps to their customers and clients in a shorter amount of time, as it drastically decreased the time spent on regression testing.

5. More rapid software development

DevOps aids in the delivery of apps more quickly, and this is since the product is delivered fast. The completed software development more quickly aids in your company’s overall growth and operation.
