DevOps is currently the most popular methodology for developing enterprise scale software systems. It is essentially an agile methodology that emphasizes communication, collaboration and integration between software developers and personnel involved in operations such as IT administration. DevOps was motivated by the need to address the implications of the well-known interdependence between software development and IT operations. DevOps is already helping organizations to rapidly produce software products and services.
Automation in developing, testing and deployment tasks is at the heart of DevOps. Organizations employing DevOps deploy software up to as much as thirty times more frequently than other enterprises, while having much shorter lead times. Hence, all organizations that employ DevOps make use of a rich set of tools that automate DevOps activities across the entire lifecycle of DevOps processes, including planning, coding, builds, testing, deployment, operations, as well as monitoring and control. These tools enable organizations to implement lean management and continuous delivery practices across the entire DevOps lifecycle. As a result, it’s important that DevOps developers understand, learn and leverage the ecosystem of DevOps tools.
DevOps planning and coding tools facilitate developers in organizing their development tasks, as well as in structuring their code in proper repositories that are accessible by other members of the DevOps teams. Prominent examples of such DevOps tools, include:
DevOps automates the build process as a means of incorporating and deploying changes to the software codebase. Revised versions of the code can be built with just one click, which boosts agility in software development and deployment. Prominent build tools in the DevOps ecosystem include:
Continuous and automated testing is at the heart of the DevOps methodology. In most cases, modern DevOps projects involve Test-Driven-Development (TDD), a discipline where tests are written prior to the code of a given use case. Testing activities are supported by tools like:
There is no DevOps without automated deployment of software based on proper software configurations over the available IT infrastructure. Thus, there are various tools that manage deployment configurations, while at the same time automating their deployment. In particular:
Beyond Jenkins, there are also other continuous integration servers, such as Bamboo, which offer similar features and are also attracting the attention of the DevOps community. Another example of Continuous Integration (CI) server is Drone, which is probably the newest CI server in the market and is built around the concept of containers. This makes it easy to combine it with containers’ infrastructures like Docker. For this reason, Drone features a higher degree of modularity when compared to other CI servers, which makes the development and deployment of CI related plug-ins faster.
DevOps teams benefit from monitoring and management teams that provide them with insights about the status and operation of their infrastructure. Tools that help DevOps teams in this direction include:
In order to rise the wave of DevOps development, you certainly need to acquaint yourself with a range of tools that support the entire lifecycle of DevOps activities. In this post we have presented some of them in order to help you understand the structure of the DevOps tooling ecosystem and accordingly to start your tooling understanding endeavors on the right foot.
