Configuration management and Infrastructure as code

Configuration management is the control of all configurations of the environments hosting the software application.

In DevOps, configuration management processes are generally fairly well automated. Configurations are encapsulated as code or scripts and controlled by using a version control tool.
When the environment changes, the automated system will take responsibility for setting up the environment and managing the configurations manually.

Learn how configuration management helps the ABCloudz DevOps team build robust and stable systems for your needs.

Why is configuration management important?

Building robust and stable systems

Configuration management helps to build robust and stable systems through the use of tools that automatically manage and monitor updates to configuration data.
Building scalable systems

Configuration management enhances the scalability of the IT infrastructure without a corresponding increase in IT administrative staff to manage these devices / systems.
Building a secure system

Configuration management reduces the risk of system hacks and data theft.
Always up-to-date information

Configuration management helps to keep up-to-date information about the system architecture and the resources used.

Configuration management includes two practices:

Infrastructure as code

Infrastructure as code includes configuring servers, networks, and other computing resources that are part of a configured IT infrastructure. So, all these details will be recorded as a file or code and checked with a version control tool.

The infrastructure configured in DevOps will be fully automated and follow the script, starting with the installation of servers, their configuration, setup of the operating system, etc.

Configuration as code

Configuration as code includes parameters defining the recommended settings for successful software operation. Or a set of commands you need to run initially to configure a software application. It can be the configuration of each of the software components you need to install, or specific user roles, rights, etc.

Benefits of Configuration Management

All configurations and infrastructure details are version-controlled, which is a big advantage when implementing DevOps.

# 1) It helps the DevOps team manage server and configuration changes automatically and quickly debug if something fails within a short time. Also, it allows you to quickly revert to a previous version without causing any interruptions in the work of consumers.

# 2) These scripts are located on a central server. Everyone in the DevOps team knows what is in each of these scripts and what changes have been made to each of these versions. It also allows the team to downgrade to an older version if there are any problems with the latest versions.

Imagine if the server crashed, how long it would take to manually recover it. And now, having defined the infrastructure as scripting and versioning, we can immediately restore by downgrading to an earlier version.

# 3) Managing configurations as code also prevents accidentally making changes to the system and errors caused by it.

Configuration management is almost completely automated, thanks to the unique software developments of our DevOps engineers. Taking the best from imperative and declarative programming, our engineers can reduce human usage by 95% when installing or upgrading systems.

This simplifies the debugging task for developers but also eliminates human error that leads to error-free infrastructure setup at all stages of the project. This results in cost savings, improved quality, and reduced time required for automatic configuration.
