DevOps has become quite a buzzword over the last few years. The DevOps model has proven to be an invaluable tool for firms experiencing challenges with respect to faster product deployments and on-time product releases. DevOps has brought in more than just a new technology; it has promoted a new way to function by bridging the gap between development and operations teams, two essential areas for the success of any IT organization.

The concept of DevOps stems from the merging of development (Dev) and operations (Ops) teams. DevOps processes typically consist of 8 stages: plan, code, build, test, release, deploy, operate, and monitor. The goal of DevOps is to enable developers to develop applications faster and maintain existing deployments of software more easily than the traditional software development process.
Together, the development and operations teams strive to build a more agile and reliable framework that is built on trust, transparency, and continuous communication to improve productivity and speed of software development. It also establishes a collaborative culture as well as improves efficiency through automation. Thus, organizations can better serve their customers and compete more effectively in the marketplace. In order to deliver faster results, developers must understand all the phases of the DevOps lifecycle as shown below:
As DevOps practices have been adopted quickly over the past few years, DevOps tools have become increasingly popular. In general, no single DevOps tool can fulfill every DevOps requirement, so there is a wide variety of DevOps tools for different DevOps requirements. Before delving into the top DevOps tools, let’s first see what exactly DevOps tools are.
What are DevOps Tools?
The concept of DevOps is more of a cross-functional approach to working. Using DevOps services effectively reduces the time involved in SDLC (Software Development Life Cycle) and ensures the delivery of foolproof, high-quality applications on a continuous basis. These cultures promote the use of a DevOps toolchain to automate the software development process, such as build, conflict resolution, dependency management, deployment, etc., thereby reducing manual effort. By using these tools, developers, operations, security, or business teams can effectively share information and exchange technical tasks for the purpose of delivering a high and effective quality product.
DevOps tools cover every aspect of software development, from version control to monitoring and deployment. Several DevOps tools have been developed in the past few years to assist you with multitasking. Using the right DevOps tool can help you with:
- Accelerated Development
- Real-time monitoring
- Enhanced Operational
- Efficiency Quicker Release
- Continuous Integration and Continuous Delivery (CI/CD)
- Frequent Deployment
- Faster Recovery Time
- Increased collaboration
- Faster Rate of Innovation
- Seamless Flow Across Value-Chain
Top DevOps Tools
Listed below are the top 15 DevOps tools, along with their key features to help you decide which tool to use.
Source Code Management and Building Tools
GitLab is a collaborative code repository and software development platform for large DevOps and DevSecOps projects. This tool provides a complete (all-in-one) DevOps solution for the rapid development and delivery of software. The platform makes it possible for teams to perform the entire process, from Planning to SCM (Supply Chain Management) to Delivery and Monitoring to Security of Software products. Teams can deliver software more quickly with GitLab while reducing development costs and security risks.

Open-source container orchestration platform Kubernetes is the most popular tool for Container Management. Google engineers founded it in order to manage containers at scale. This initiative aims to automate deployment, scalability, and operations of application containers across clusters of hosts. It supports a number of container tools, including Docker. Through Kubernetes orchestration, you can build applications that span multiple containers, schedule them across a cluster, scale them, and manage their health over time.
- Monitor your application’s health and make changes to its configuration simultaneously
- Deploys and scales containerized applications without manual intervention of technical team.
- Containerized apps don’t have to be tied to a single machine. Instead, they can be deployed to a cluster of computers.
- Capable of self-healing like restarts containers when fail, kills containers when when they dont respont do user-defined health check, etc.
Open-source DevOps tools like Apache Mesos allow you to manage computer clusters. Dynamic resource sharing and isolation are employed to handle workloads in a distributed environment. Mesos can be used for deploying and managing applications in large-scale clustered environments. Twitter, Airbnb, MediaCrossing, Xogito, and Categorize are among the prominent Mesos users.
