Infrastructure as Code (IaC) - an introduction

Cloud computing offers flexible computing resources in the cloud. Infrastructure as Code (IaC) automates the provisioning and modification of these resources using code.

With IaC, you can quickly create as many instances of your entire infrastructure as you need, in different provider regions, from a single source of truth: Your declarative code. This has many benefits, ensuring that you create resources consistently and without errors, while reducing management and manual setup time.

The Key Benefits of IaC

• Fast deployment: Automation speeds up the deployment process.
• Hassle-free recovery: Configuration errors can be fixed quickly.
• Consistency: Resources are consistent and less vulnerable.
• Rapid changes: Modifications can be implemented quickly.
• Reusability: Parts of the infrastructure can be reused in other projects.
• Version control: Code is stored in versioning systems.
• Visibility: The code acts as documentation.

Key IaC Tools

IaC provides an efficient way to manage cloud infrastructures. With the right tools, you can take full advantage of it.

First up is Terraform - an open source tool that manages IaC deployments. It supports multiple cloud providers and ensures that the cloud state matches the code.

Other tools that use IaC include Docker, Kubernetes, Hashicorp Packer, Ansible, Chef, and Puppet. Each of these tools uses the IaC methodology to define and manage the infrastructure desired in their respective domains.
