Best Open Source DevOps Tools to Use in 2023


In the modern IT industry, nothing is possible without the cooperation of teams, a product that depends entirely on the cooperation of developers and operational staff to contribute to its creation.

Simply put, “DevOps” refers to a group of modern IT techniques that are intended to better integrate software developers and operations staff so they may collaborate more effectively on the same project.

DevOps tools have several advantages. Here are some of those.

  1. Improved and quicker product delivery.
  2. A quicker resolution to problems and less complexity.
  3. More availability and scalability.
  4. Improved operational conditions.
  5. Better use of resources.
  6. Enhanced automation.
  7. Increased transparency of system results.

In the IT sector, this kind of cooperation is carried out via open-source DevOps tools. These open-source DevOps tools let businesses use the best technology with the least amount of complexity. They are designed to work together and communicate with other software tools.

There are more excellent open-source DevOps tools available in addition to these that might be of great use to you. Let’s examine these top Open Source DevOps tools in more detail.

Top Open-Source DevOps Tools

1. Git

Git is a DevOps tool for managing source code. Basically, it is a version control system that can efficiently manage small to big projects and is free and open-source. It is perhaps the most well-known DevOps tool.

Git is a program that is primarily used for storing code and monitoring code changes. It began as a tool to aid Linux developers in maintaining the Linux source code. However, it has subsequently been upgraded to add several advanced features.

Installing the git package on Linux enables immediate command-line access to Git. You may also set up Git on Windows. Version control is one of the finest DevOps strategies. With version control, software engineers may version the program, share it, work together, combine versions, and create backups.

This version control system will track all the changes that are necessary for the DevOps methodology. Developers can maintain a local copy of the changes they produce using Git, like a distributed version control system. The DevOps philosophy is founded on the idea that using GIT as a DevOps tool facilitates cooperation and leads to quicker release cycles.

Git is useful and makes it simple to track changes made by each team while working in large organizations where several teams collaborate on the same project. It aids in version control, code management, and code tracking.

2. Kubernetes

The fact that Kubernetes is at the top of the list of open-source DevOps solutions last year is no surprise considering the widespread use of microservices and container-based computing.

Container orchestration is carried out using Kubernetes, whose popularity increased by 48% in 2020. Kubernetes can automate the deployment, management, and scaling of containers in production rather than releasing microservices one at a time. The Cloud-Native Computing Foundation hosts Kubernetes, and Kubernetes is often known as K8s.

It is used to streamline application management by automating operational tasks associated with container management and providing built-in commands for deploying applications, rolling out changes to applications, scaling applications up or down to meet changing requirements, monitoring applications, and more.

Similar to other open-source DevOps tools Kubernetes is licensed under Apache 2.0

3. Docker

An open-source platform, Docker is ideal for creating, distributing, and executing programs. With the use of Docker, you can separate your programs from your infrastructure, enabling quick software delivery. You can manage your infrastructure using Docker in the same manner that you manage your apps.

System administrators and developers, two key players in DevOps, are the target audience for the product. With Docker, developers can concentrate on creating applications rather than worrying about the platform/environment on which they operate.

In the case of Docker, the host directly allocates the resources, as opposed to virtual machines. This enables you to operate several Docker containers as opposed to a small number of virtual machines. Each container allocates resources on its own based on the demands of the application.

Like other DevOps tools, Docker is an open-source platform that enables developers to create, distribute, operate, update, and manage containers and executable components that integrate application source code and the dependencies and libraries required to execute the code in any setting.

4. Istio

Organizations can upgrade their efficiency more quickly and securely by using Istio to secure, connect, and monitor microservices. Without modifying the application code, Istio controls how traffic moves between services, enforces access rules, and aggregates telemetry data.

Microservices are a practical approach to development, but they also raise new issues with design and development. Users specifically need to know how to uniformly implement networking regulations like security, encryption, observability, and telemetry aspects across all of their services.

Google introduced Istio as an open-source service mesh solution in 2016 along with IBM, Lyft, and other companies. Istio, which is based on the high-performance Envoy proxy, offers a customizable overlay for Kubernetes-based microservices.

5. Packer

Using a single-source configuration, Packer is an open-source DevOps tool for producing identical machine images for several platforms. Packer is fast, lightweight, and compatible with all major operating systems. It can create machine images for several platforms simultaneously.

Hashicorp developed it so that it could generate identical machine images for several platforms from a single JSON configuration file. When it comes to developing immutable architecture, this tool is highly effective. Packer is compatible with Azure, GCP, and AWS.

Packer uses a service principal to log in to Azure. With applications, services, and automation tools, you may leverage an Azure service as a secure identity. 

To Sum it Up All

These are the best open-source DevOps tools. I hope this article helped you to get familiar with the best DevOps tool that can help you manage your tasks efficiently. If you find this blog useful consider sharing it with your developer friend who is searching for the best open-source DevOps.
