How does DevOps work?

DevOps is a methodology for improving work throughout the software development life cycle. A DevOps process may be thought of as an endless loop that comprises planning, coding, build, testing, deployments, operation, tracking, and response plans that reset the cycle.

Ideally, DevOps means that your IT team will create software that fully meets your requirements, is deployed without wasting time, and runs optimally on your first attempt. Organisations pursue this goal by combining culture and technology.

The evolution of DevOps

Software development consultant Patrick Debois is known for naming the conference DevOps Days and coining the term DevOps in 2009. DevOps has addressed the shortcomings of agile software development techniques. Iterative and rapid code development did not always lead to iterative and rapid code delivery. The open source ticketing system goes hand in hand with DevOps implementations.

ITIL promotes stable, dependable, and predictable IT, whereas Agile promotes cooperation and change. DevOps hit a chord with both parties. Enterprises can use both ITIL and DevOps, especially when using the cloud. Later, in 2013, the book The Phoenix Project popularised the DevOps idea. Early supporters of DevOps included the following key players:

  • Debora and collaborator Andrew Clay Schaefer.
  • The authors of the Phoenix project are Jean Kim, Kevin Beer, and George Spafford.
  • Flickr’s influential early adopters were Paul Hammond and John Allspaw.
  • John Willis, the advocate of containerisation.

Formalised DevOps Approach

As DevOps became more prevalent, organisations formalised the DevOps approach. For example, Retailer Target has developed a DevOpsDojo training method. Vendors are promoting the DevOpsenabling feature of the tool, from collaborative chatbots to CI / CD suites integrated with cloud services. “Dev Ops Engineer” quickly became a job title. DevOps is evolving with the advent of artificial intelligence that enhances everything from code writing to incident management. AI for DevOps (or AIOps) means more intelligent automation and shorter latency, seamlessly transforming business requirements into technology products, but there are still many obstacles to achieving this.

Methodologies and Plans

Because it supports DevOps as a mechanism for agile professionals to extend their technique to production, DevOps is related with agile software development. This approach is also called the counterculture of IT service management methods represented by ITIL. DevOps has no official framework. Organizations must comprehend DevOps, Agile and Waterfall production, Site Reliability Engineering (SRE), and SysOps, as well as the important context of variation within DevOps, in order to enhance the approach.

DevOps Waterfall development.

The waterfall development involves a series of steps and gates in a straight production line. The phases are stated below:

  1. Requirements
  2. Analysis
  3. Design
  4. Coding and implementation
  5. Testing operations and deployment
  6. Maintenance.

The waterfall team tests the new code in an independent quality assurance (QA) environment. In IT operations, we deploy multiple releases simultaneously as comprehensive control. Support is the company’s responsibility—the waterfall approach results in longer wait times between software versions.

Because the production and operations teams operate independently, programmers are often not aware of operational issues preventing code from functioning as planned. With fewer gates and more continuous processes, the DevOps paradigm integrates development, quality assurance, and IT service tasks. For example, the responsibility of some operations teams shifts from the left side of the app delivery pipeline to the development team. IT operations provide feedback on improving your code.

DevOps with Agile development

The agile team focuses on a gradual and rapid code creation and deployment cycle called sprints. Each sprint is repeated at the end, making the software incredibly flexible and adaptable to changing requirements. However, this cycle can lose the original vision of the project. DevOps stems from Agile’s success in speeding up development and the realisation of separation between development and operations teams and between IT and the organisation’s business side, significantly hindering agile software delivery to users. Agile is a software development methodology.

Hence, the development and operations teams have different goals and leadership in an agile-only workflow. As a result, when a company employs DevOps and Agile, the development and operational teams control the coding all through the software development lifecycle. So, we recommend getting DevOps consulting services for a better experience.
