For IT professionals, DevOps is not a new term. As the term suggests, DevOps is a combination of two words – development and operations. It refers to the philosophy that emphasizes better collaboration and communication between these two teams in an organization. This methodology focuses on the adoption of automation, iterative software development, and programmable infrastructure deployment and maintenance. Organizations that adopt DevOps practices use continuous integration and continuous deployment tools so as to automate various tasks.
Though DevOps is a mindset, IT teams find it difficult to do anything without the right set of tools. Automation is promoted in DevOps practices and various tools are used to support the CI/CD pipeline, containers, and cloud hosting. You will find tools for building automation and source code management, continuous integration, application deployment and configuration management, and infrastructure deployment. Whether you take a paid or free DevOps course, you will learn how to use those tools. But do you know what those tools are?
This article describes some of the best DevOps automation tools used by organizations that follow DevOps practices.
Top 10 DevOps Automation Tools
When you talk about source code management, Git is the first name that you will come across. An open-source version control system, Git is used to tracking changes in the source code and allows multiple developers to work together on non-linear development. The tool allows every developer to create an entire copy of the code on their local systems. A central place to upload changes and download the versions created by other developers results in improved collaboration by simplifying working on projects with multiple employees and teams.
Jenkins is an automation tool popularly known for its use in continuous integration. It is a leading open source automation server that offers hundreds of plugins to support designing, deploying, and automating any project. Apart from being useful as a CI server, Jenkins can be turned into the continuous delivery hub for any project. It is a self-contained Java-based program with packages for Linux, Windows, macOS, and other Unix-like operating systems. The tool can easily distribute work across various machines, and help drive builds, tests, and deployments across various platforms quickly.
Nagios is a powerful monitoring system that allows organizations to find and resolve IT infrastructure problems before they can affect crucial business processes. Designed with flexibility and stability, the tool minimizes the chances of business processes being negatively impacted by unknown outages. With Nagios, you can plan for infrastructure upgrades, automatically fix problems when detected, and ensure that the organization’s SLAs are being met.
Splunk is a Data-to-Everything platform that empowers people to predict, find, and solve problems in real-time. It answers questions across the business, IT, security functions, and DevOps with best-in-class intuitive visualizations, investigative capabilities, and seamless collaboration.

The tool is trusted by 91 of the Fortune 100 companies and Intel, Comcast, Coca-Cola, Transunion, and Yelp are some of its popular customers.
Chef aims to improve the lives of IT operators through software automation. It helps operations teams collaborate effectively and adopt a DevSecOps (Development, Security, and Operations) approach so as to deliver and maintain infrastructure and applications that are secure and nimble by design. The tool is built for heterogeneous infrastructure, designed for collaboration, and has demonstrated results in mission-critical environments. Popular brands like IBM, Alaska Airlines, Capital One, Danske Bank, Cerner, and Facebook use Chef for its class-leading governance and compliance features.
A well-known configuration management tool, Puppet allows you to write simple code and deploy it to the servers that have issues and roll them back to their previous working states. It implements infrastructure as code so that you can test the environment and make sure that it is deployed accurately. Companies use Puppet to automate their private cloud management and IT operations to offer consistency and allow IT teams more time for innovation. It comes as no surprise that Puppet is used by Spotify, Google, Staples, AT&T, and the US Air Force.
Docker is a DevOps tool basically known for taking away mundane repetitive configuration tasks and used throughout the development lifecycle for fast and easy application development. Its comprehensive end-to-end platform includes CLIs, UIs, security, and APIs that are engineered to work together across the entire lifecycle of application delivery. It allows you to integrate other development tools like GitHub, VS Code, and CircleCI throughout your development pipeline.
The official website of Kubernetes describes the tool as an open-source system used to automate deployment, scaling, and management of containerized applications. Also called K8s, this tool builds upon 15 years of experience of running production workloads at Google, along with best-of-breed ideas and practices from the community. It groups containers that make up an application into logical units for easy management and discovery. Kubernetes’ flexibility grows with you to deliver applications consistently and easily despite the complexity of your needs.
Originally meaning accumulator of knowledge, Maven is a tool used for building and managing any Java-based project. It allows a developer to comprehend the complete state of a development effort in the shortest possible time. Maven makes the build process easy, provides a uniform build system, offers quality project information, and encourages better development practices. The tool also suggests some guidelines on how to lay out your project’s directory structure.
Offered by Red Hat, Ansible is a simple IT automation engine that automates various IT needs like configuration management, cloud provisioning, intra-service orchestration, and application deployment. Rather than just managing a single system at a time, Ansible models an IT infrastructure by describing how all of the systems interrelate. You can extend the power of Ansible with the Red Hat Ansible automation platform to scale automation, speed productivity, and manage complex deployments across entire IT teams.
