Infrastruktuurikoodaus

Infrastruktuurikoodaus, often referred to as Infrastructure as Code (IaC), is a practice in which infrastructure development and management are treated as if they were software code. This approach involves using machine-readable definition files, rather than physical hardware configuration or interactive configuration tools, to provision and manage infrastructure. The core idea is to automate the deployment and management of infrastructure, making it repeatable, versionable, and testable, similar to how software development is managed.

IaC allows for the creation of infrastructure through code, enabling teams to define servers, networks, databases, and other infrastructure components in configuration files. These files can then be stored in version control systems like Git, allowing for tracking changes, collaboration, and rollbacks. This methodology brings several benefits, including increased speed and efficiency in provisioning, reduced risk of human error, improved consistency across environments, and enhanced security through standardized configurations.

Popular tools that facilitate IaC include Terraform, Ansible, Chef, and Puppet. These tools enable the declarative or imperative definition of infrastructure. Declarative approaches define the desired end-state of the infrastructure, and the tool figures out how to achieve it. Imperative approaches specify a sequence of commands to execute to build the infrastructure. By adopting IaC, organizations can achieve greater agility, scalability, and reliability in their IT operations.
