The DevOps aspects relate to the different areas of software development and operations that improve once the DevOps methodology, the DevOps culture, is put into practice. Below we list the aspects behind the idea of effective software creation, testing and deployment, and of improved communication between developers and technical departments.
People
People are one of the key factors in DevOps. As mentioned earlier, DevOps includes developers, testers, the operations team and possibly other teams involved. These teams are no longer isolated from one another. Instead, they create the conditions for greater communication and collaboration throughout the software development lifecycle, and may merge into a single team. Such a team is characterized by higher awareness, mutual trust, a strong customer focus, and the ability to learn from shared experience and to explore new areas, which means building multidisciplinary skills.
Processes
Processes define what is to be done and how it is to be done, so that the entire software development lifecycle can be reliably delivered from start to finish. Clearly defined processes support the DevOps goals of delivering software faster and better. This can be achieved through a balanced use of the tools, processes and methodologies already in place.
Tools
DevOps teams use tools, of which there is now a significant and constantly growing number, to automate and accelerate processes and to increase the reliability of the development process. It is important, however, that these tools are connected and work together as a tool chain, so that the goals of the DevOps approach are actually met. The core tools are those that support continuous integration and continuous deployment (CI/CD), Infrastructure as Code (IaC), automation and collaboration.
Why the DevOps aspects matter
The DevOps aspects are increasingly important in modern software development because they enable organizations to deliver software faster, more reliably and more securely, which ultimately increases their competitiveness in the marketplace.
