# What is platform engineering?

Platform engineering is:

- A central repository of architectural decisions made by DevOps teams
- An Internal Developer Platform (IDP) that allows those decisions to be implemented throughout DevOps teams at scale
- Feedback processes that allow architectural decisions to be improved over time

While platform engineering is not limited to CI/CD pipelines, CI/CD platforms provide a convenient foundation on which to implement an IDP because:

- They have already been deployed into enterprises on supported infrastructure
- DevOps teams already know how to use them
- They have rich CLIs and APIs to support automation
- They manage execution environments in which to run automated tasks
- They already have access to existing DevOps systems

Octopus can function as an IDP through a combination of IaC (with the [Terraform provider](https://registry.terraform.io/providers/OctopusDeployLabs/octopusdeploy/latest/docs)), Git based workflows (with [Config-as-code](/docs/projects/version-control)), and specially designed step templates to deploy and track changes to deployment projects and runbooks.
