What is DevOps?

Share

There are many schools of thought around what DevOps is. Put simply, DevOps is a combination of three core concepts: cultural philosophies, technical practices and supporting tools.

In this blog we break down the key principles, what they mean and how they contribute to the DevOps methodology.

Cultural change

Traditionally, companies work in silos between development and software operations. DevOps culture, however, is characterised by increased collaboration between these development and operations teams. Arguably an extension of Agile practices, common cultural practices include:

  • Decreasing silos between teams
  • A shared responsibility ethos
  • Autonomous/empowered teams
  • Improving quality
  • Valuing feedback
  • Increasing automation

Whether integrating functions as a single department or team, the cultural change associated with DevOps will help organisations to deploy software more frequently, maintain service stability and gain the speed necessary for more innovation.

Technical practices

Flexibility and ease of use should be at the core of every platform. Practically, this means that if your team tells you they need something, you can make it happen within days or weeks; not months. The Holy Grail of software development and engineering is a system that supports rapid change with high resiliency to failure.

Some key technical practices commonly adopted include:

  • Infrastructure as code: this allows teams to manage configurations and automate the provisioning of infrastructure in addition to deployments. It also drives valuable development practices such as version control, testing, use of design patterns etc.
  • Continuous Integration/ Deployment (CI/CD) pipelines
  • Automation: alongside deployment, automation of testing, monitoring tool configuration and more

Supporting tools

There are a number of tools on the market to help automate environment deployment, configuration and package management locally and in the cloud. However, these tools are unlikely to generate success without the cultural elements of DevOps.

Space for change

DevOps practices and tools can be used to automate more than code testing and teams should constantly look to iron out any part of a development cycle that slows processes down. This importance gives rise to the DevOps concept and, in turn, the demand for people with these collaborative skills.

Sparta Global aims to shape the next generation of tech talent by providing training courses that prepare students for a tech career and teach the core engineering skills they need to work on software products, including DevOps.

We invest in the recruitment of high calibre graduates for our Technical Consultant courses, where students build up contemporary and highly relevant skills through classroom training, projects and practical learning. Our Spartan graduates then have the opportunity to work as a consultant with one of our client partners; crafting real solutions for real problems and bringing fresh ways of thinking to a new client.
