What is DevOps and how does it work ?

Posted on October 22, 2003


What is DevOps, and how does it work?

The word “DevOps” is an excellent combination of the words “development” and “operations.” It means that a company’s application development and IT operations teams work together or share tasks.

In its broadest sense, DevOps is a way of thinking that encourages better communication and teamwork between these teams and others in an organization. At its most basic level, DevOps means using iterative software development, automation, and programmable deployment and maintenance of infrastructure. This term also refers to changes in culture, like building trust and unity between developers and system administrators and making sure that tech projects meet business needs. The software delivery chain, services, job roles, IT tools, and best practices can all be changed by DevOps.

DevOps is not a technology, but most DevOps environments use the same methods. Among them are the following:

  • Continuous deployment and integration (CD/CI) tools, with a focus on automating tasks;
  • systems and tools that help with DevOps adoption, such as real-time monitoring, incident management, configuration management, and collaboration platforms; and
  • cloud computing, microservices, and containers that are used in tandem with DevOps methodologies.

A DevOps approach is one way that IT staff carry out projects that meet the needs of the business. Agile software development, IT service management frameworks like ITIL, project management rules like Lean and Six Sigma, and other strategies can all work together with DevOps.

Some IT professionals think that just putting “Dev” and “Ops” together is not enough and that the term “DevOps” should include business (BizDevOps), security (DevSecOps), and other areas.

 

How does DevOps work?

DevOps is a different way of doing things that are meant to make work better all the way through the software development lifecycle. The DevOps process can be considered as an endless loop with these steps: plan, code, build, test, release, deploy, operate, monitor, and plan again based on feedback, which starts the loop over.

In an ideal world, DevOps means that an IT team writes software that meets user needs perfectly, deploys quickly, and runs well on the first try. Culture and technology are both used by organizations to reach this goal.

Developers and other people with interest in the project talk about the project, and developers work on small updates that go live on their own.

IT teams use CI/CD pipelines and other forms of automation to move code from one step of development or deployment to the next without having to wait. Teams look at changes right away and can make sure releases meet standards by enforcing policies.

It’s easy to write software quickly, but it’s much harder to write software that works. DevOps followers use containers or other methods to make sure that software behaves the same way from development to testing to production.

This is how they get good code into use. They make changes one at a time so that problems can be tracked down. Configuration management is used by teams to make sure that deployment and hosting environments are always the same.

When they find problems in live operations, they often fix the code by doing a blameless post-mortem investigation and keeping feedback channels open.

Developers might provide support for live software, which means it’s up to them to think about runtime issues. IT operations administrators may take part in software design meetings and give advice on how to use resources safely and efficiently.

Post-mortems can have contributions from anyone. The more these experts work together and share their skills, the more they can help build a DevOps culture.
