DevOps: Principles, Practices, and DevOps Engineer Role

Development and operations used to be separate; developers wrote the code while system administrators deployed and integrated it. This resulted in limited communication between parties, making them largely divided within projects. It worked when Waterfall development was the norm, but with Agile and continuous workflows dominating the industry, it makes more sense to combine DevOps as a service for software development.

DevOps is among the most used software development practices today, with many industry-leading companies relying on it for better performance, competitiveness, and success. You can do the same by hiring a seasoned DevOps engineer. Moreover, you may want to consider the engineer’s software development practices and technologies, such as DevOps automation, for more added security and efficiency.

Principles of DevOps

The main principles of DevOps as a service are culture, automation, measurement, and sharing. Here’s a quick overview of what they are.

  1. Culture

DevOps is the mindset and culture to create strong collaborative bonds between development and infrastructure operations teams. The culture is established upon pillars, such as gradual changes, constant communication and collaboration, early problem-solving, and shared end-to-end responsibility.

  1. Automation

DevOps automation automates many aspects of development, configuration, testing, and deployment procedures to minimise or eliminate repetitive tasks. This way, everyone can focus on other critical tasks. Automation also improves security, especially when developing in a cloud environment. DevOps engineers achieve this with the latest industry best practices and tools.

  1. KPI measurement

Decisions must be based only on factual information. For optimum performance, teams must oversee the progress of activities throughout the DevOps process. Measuring KPIs can help them identify what’s working and what needs improvement.

  1. Sharing

Sharing is caring also applies to DevOps as a service because it emphasises the importance of collaboration. That means sharing feedback, knowledge, and best practices among teams to promote transparency, remove constraints, and generate collective intelligence.


DevOps automation requires a delivery cycle consisting of planning, testing, development, deployment, release, and monitoring. DevOps engineers must actively cooperate with everyone in the team. Here are the core practices involved in DevOps:

  • Agile planning
  • Continuous development
  • Continuous automated testing
  • Continuous integration and delivery
  • Continuous deployment
  • Continuous monitoring
  • Infrastructure as a code
  • Containerization
  • Microservices
  • Cloud infrastructure

What does a DevOps engineer do?

The role of a DevOps engineer is to introduce continuous delivery and continuous integration workflow while applying their understanding of DevOps tools and knowledge of programming languages. Their role may also differ based on the project. For instance, some may require engineers with broader responsibilities and skill sets, and others may need an engineer for a specific area of the DevOps lifecycle that can work with DevOps automation.
