Building in the cloud console is not scalable or repeatable, so infrastructure as code is used to automate provisioning with versionable configuration files.
Adopting IaC ensures consistency across environments, simplifies developer onboarding, eliminates configuration drift, and minimizes the risks of manual work.
Terraform uses declarative configuration files to describe the desired end state, and its core workflow involves planning and applying changes to reach that state.
Terraform's architecture consists of a core that manages state and a system of providers that connect to various cloud, on-prem, and SaaS services.
IaC provides a consistent workflow for the entire infrastructure lifecycle, from initial provisioning on day one to ongoing evolution and eventual decommissioning.
Teams can scale IaC by using version control for collaboration and abstracting complexity with reusable modules from a central registry.
When choosing an IaC tool, consider factors like multi-cloud support with Terraform versus single-provider tools like AWS CloudFormation or scripting languages like PowerShell.
This demonstration walks through the practical steps of creating a configuration file and using Terraform commands to provision a Linode instance.
