# Legacy Infrastructure

This topic describes different types of legacy infrastructure, that is, dedicated infrastructure to facilitate and execute chaos experiments.

Based on the target environments, you can install chaos infrastructure as a Kubernetes service, a Linux daemon or a Windows agent.

There are different types of chaos infrastructure such as:

* [Legacy Infrastructure (Kubernetes)](/resilience-testing/chaos-engineering/use-chaos-engineering/infrastructure/types/legacy-infra/kubernetes.md)
  * [OpenShift](/resilience-testing/chaos-engineering/use-chaos-engineering/infrastructure/types/legacy-infra/openshift.md)
* [Linux](/resilience-testing/chaos-engineering/use-chaos-engineering/infrastructure/types/legacy-infra/linux.md)
* [Windows](/resilience-testing/chaos-engineering/use-chaos-engineering/infrastructure/types/legacy-infra/windows.md)
