Configuration Management Tools for DevOps
DevOps is a combination of software development and operations — and as its name suggests, it’s a melding of these two disciplines in order to emphasize communication, collaboration, and cohesion between the traditionally separate developer and IT operations teams.
In the past, To maintaining IT infrastructure, deploying applications, and provisioning environments we have to involved in many manual efforts, iterative tasks. But in today’s DevOps platform, true automation of these tasks has arrived. The most benefits of automated configuration management range from time savings to elimination of human error.

Cloud platforms allow teams to deploy and maintain applications serving thousands of users, and the leading open source configuration management tools have wrapped in ways to automate all relevant processes.
So you can find the configuration management tool that’s right for you some tools you may have known about for years, while others may be new.
Configuration management systems are designed to make controlling large numbers of servers easy for administrators and operations teams. They allow you to control many different systems in an automated way from one central location. While there are many popularm configuration management systems available for Linux systems, such as Chef and Puppet, these are often more complex than many people want or need. Ansible is a great alternative to these options because it has a much smaller overhead to get started. Ansible on GitHub
Puppet is an open source server automation tool for configuration and management. It works on Linux, Unix, and Windows systems and performs administrative tasks (such as adding users, installing packages, and updating server configurations) based on a centralized specification. Puppet on GitHub
Next to Puppet, Chef is the other heavyweight in the CM and automation arena.
“Like Puppet, Chef is also written in Ruby, and its CLI also uses a Ruby-based DSL. Chef utilizes a master-agent model, and in addition to a master server, a Chef installation also requires a workstation to control the master. The agents can be installed from the workstation using the ‘knife’ tool that uses SSH for deployment, easing the installation burden.” Chef on GitHub
Others Must-Have DevOps Tools
Nagios is very popular open source monitoring tools we can monitor anything, you will be able to monitor hosts resources by web interface. Nagios is useful for keeping an inventory of your servers, and making sure your critical services are up and running. For using a monitoring system, like Nagios, is an essential tool for any “production server environment’’ see more
5. ELK – Elasticsearch, Logstash, Kibana
The ELK Stack is the most common log analytics solution in the modern IT world. It collects logs from all services, applications, networks, tools, servers, and more in an environment into a single, centralized location for processing and analysis. We use it for analytical purposes (e.g., to troubleshoot problems, monitor services, and reduce the time it takes to solve operational issues). Another use for this tool is for security and auditing (e.g., to monitor changes in security groups and changes in permissions). After receiving alerts on these issues, it is easy to act on unauthorized users and activities. We also use ELK for business intelligence, such as monitoring our users and their behavior.
The Elasticsearch ELK stack:
- Elasticsearch for deep search and data analytics
- Logstash for centralized logging, log enrichment and parsing
- Kibana for powerful and beautiful data visualizations
By their powers combined, these three tools pair to provide you with all the tools you need to understand exactly what is happening in your business, from your systems generated data to each and every click from your users.
Jenkins is an open source Continuous Integration tool that monitors execution of repetitive jobs, such as building a software project or jobs ran by cron. It’s written in Java programming language and designed to test and report on isolated changes in a larger code in real time.
It is Originally started as Hudson in 2004 but due to a dispute in 2011 they forked and continued under the name, Jenkins.
It can be used to build software, deploy software, or websites to various endpoints or to run unit/behaviour-driven software tests.
Since launching back in 2013, this industry newbie has taken the DevOps and software development world by storm. The key to Docker’s success is its lightweight containerization technology:
“Their technology deploys software applications with all the necessary parts in a container, thereby ensuring it will run on any Linux server, regardless of configuration and/or settings. Containers can be created, configured, and saved as templates for use on other hosts running the Docker engine. These templates can then be used to create more containers with the same OS, configuration, and binaries.”
8. Git (GitHub)
Git was created 10 years ago following the Linux community’s need for SCM (Source Control Management) software that could support distributed systems. Git is probably the most common source management tool available today. After running Git internally for a short period of time, we realized that we were better suited with GitHub. In addition to its great forking and pull request features, GitHub also has plugins that can connect with Jenkins to facilitate integration and deployment. See more
