Infrastruktuuriascode

Infrastruktuuriascode, often abbreviated as IaC, is a methodology for managing and provisioning IT infrastructure through machine-readable definition files, rather than through physical hardware configuration or interactive configuration tools. This approach treats infrastructure as code, allowing for automated deployment, updates, and management.

The core principle of IaC is to define infrastructure components such as servers, networks, databases, and load balancers in configuration files. These files can then be version-controlled, tested, and deployed repeatedly and consistently. This ensures that the infrastructure is reproducible, reducing the risk of configuration drift and human error.

Key benefits of IaC include increased speed and agility in infrastructure deployment, improved consistency and reliability, enhanced security through automated policy enforcement, and reduced operational costs. It also facilitates collaboration among development and operations teams, fostering a DevOps culture.

Common tools used for implementing IaC include Terraform, Ansible, Chef, Puppet, and CloudFormation. These tools interpret the code definitions and interact with cloud providers or on-premises systems to provision and configure the desired infrastructure. IaC is a fundamental practice in modern cloud computing and DevOps workflows.
