What is an IAC Driver?
An Infrastructure as Code (IAC) driver refers to a tool or a component that enables the automation of infrastructure management through code. It can be seen as a bridge between traditional IT processes and the modern requirement for cloud-based infrastructure management.
By leveraging code to define and provision infrastructure, IAC drivers allow teams to automate repetitive tasks, reduce human errors, and ensure consistency across environments. The foundation of IAC drivers rests on principles such as version control, automated provisioning, and configuration management.
How IAC Drivers Work
At its core, an IAC driver works by translating high-level abstractions (written in a programming language) into low-level infrastructure commands that cloud providers understand. The process generally follows these steps:
1. Definition of Infrastructure
Using configuration files, developers define the desired state of their infrastructure. This includes specifying servers, networks, databases, and any other resources needed for an application to run.
2. Execution of Code
After defining the infrastructure, the IAC driver interprets the configuration and translates it into commands (often through a provider API) that provision or modify resources in the cloud or on-premises environments.
3. State Management
IAC drivers continuously manage the state of the infrastructure. This means they can detect changes made outside of the IAC system and rectify any discrepancies, ensuring the environment matches the defined state.
Key Components of IAC Drivers
To fully grasp the capabilities and functionalities of IAC drivers, it’s crucial to understand their key components.
1. Configuration Files
These files contain the definitions of your infrastructure. They can be written in various formats, including JSON, YAML, or specialized languages, depending on the IAC tool being used.
2. Execution Engine
The execution engine is the heart of the IAC driver, responsible for processing the configuration files and executing the necessary commands to create or manage resources.
3. State Management System
This system ensures that the defined infrastructure matches the current state of the environment. It provides vital tracking and rollback capabilities, which are essential for maintaining consistency and reliability.
