Before DevOps entered the IT circuit, the development and operations teams worked in their own ways. It was DevOps that acted as the bridge between the two teams and hence came the need for an integrated configuration management system. Configuration management tools are the need for today to design, deploy, configure, and manage servers, infrastructure, etc. These tools are competent in automating and managing multi-tier applications
Teams looking to scale their products and IT ecosystem need effective configuration management tools for the management of their IT components. These tools affect all parts of the digital infrastructure and hence choosing the right one is important. Originally, software configuration management was a part of the software development cycle but as its significance evolved, it became an extensive section with infrastructure-as-a-code.
Before we look at the most popular software configuration management tools today, let us briefly understand what configuration management is.
Configuration Management (CM) is a systems engineering process for establishing and maintaining consistency of a product’s performance, functional, and physical attributes with its requirements, design, and operational information throughout its life.
