With Small misconfigured settings outbreak IT environments on a huge scale, impacting security and stability; Infrastructure as code assists to apply a stable and reliable configuration for a broad assortment of the endpoints.
Infrastructure code (IaC) is the practice of configuring infrastructure with the help of a code instead of using auser interface popular as UI or command line interface or CLI. By the help of Configuration settings, it aids in writing within configuration files and then to be applied further.
Pertaining to the highest level of configuration in files written to describe the desired state of a system, it is used to get applied against target systems, usually performed with a configuration manager mostly like Ansible or Terraform.
With this, it is evident that IaC can help solve common infrastructure management problems. Listing out a few:
• Inconsistent nature of the configuration
• Outdated documentation
• Configuring and changing the tracks
• Configuration drift detection through codes
With the goal being to obtain as many configuration settings as possible within the configuration file pertaining to a single source of truth in the current environmental state. Please note that configuration file is not meant to replace design or deployment step documentation because of the reason stating that it only states the desired rationale behind its setting. Now with Specifying system configuration within text files will permit the use of version control platforms to track changes to ensure that all changes in the environment are committed to version control before they are applied on.
Changes within text files are considered easier to track an accidental option selection within a user interface which can be entitled as a missed step within a list of tasks.
