Five Open Source DevOps Tools
By Niladri Choudhuri
Quick and improved releases are the need of the hour in today's software development
landscape. This calls for the immediate identification, correction, and updation of software
products. The DevOps model brings the development and operations teams together, in order to
improve the speed and quality of the products delivered to customers. The merging of these
two hitherto separate domains, with varied functionalities, is no doubt beneficial, but also difficult.
DevOps tools aid in simplifying this otherwise complex process of coordinating and integrating
the functions of these two teams. Many open source DevOps tools are now available to assist
DevOps professionals in the continuous integration, delivery, and deployment of products.
What are some open source DevOps tools I can opt for?
Not all things good are costly. A hoard of open source tools are at the disposal of DevOps
developers today. The following is a list of five such open source tools that are frequently
employed in the world of DevOps.
1. Chef: This is a configuration management tool that aids in automating configuration,
deployment and management of software applications. It deals with machine setup on the cloud,
on servers, and on virtual machines. Configuration management basically ensures that all the
files and software in your computers are configured correctly and are functional. Chef does
this by treating the infrastructure of your machines as pieces of code called 'recipes', which
are in turn compiled in "cookbooks".
2. Puppet: This too is a configuration management tool that works to automate provisioning,
configuration, and management of devices. CERN, Oracle, and Reddit, are among its noted users.
3. Ansible: This is an automation software that was taken over by Red Hat. This is a
simple server and configuration management tool that aims to bust complexity. Ansible can help
you with task automation, application deployment, and IT orchestration. It allows you to run
tasks in a sequence and to create a chain of events that need to happen at once on many servers/
devices. This in turn helps you automate everyday tasks, and to speed up product delivery.
4. SaltStack: This is a remote execution tool and configuration management system that
allows users to run commands on different machines along with a targeting system. This makes
Salt a multitasking system that can be used to solve multiple problems in an infrastructure.
5. Docker: This is a widely-acclaimed container technology that ensures that a piece
of software runs reliably in different computing environments. Put simply, a container is a
compilation of an application, its dependencies, libraries, and other configuration files needed
for its smooth functioning. Docker ensures that your application runs without any hiccups even
when transferred to a computing environment different from its home environment.
This list is only the tip of an enormous iceberg. Countless other open source tools are
scattered across the DevOps landscape. Choose a tool that best fits your immediate needs. None
of these tools might fit all your requirements. The trick lies in choosing the best set for you.
