+# Clusters on Managed Dedicated Hosts in AWS
+
+## Summary
+
+This enhancement proposal outlines the work required to enable OpenShift to manage dedicated hosts on AWS. 
+
+## Motivation
+
+### User Stories
+
+1. As an administrator, I want openshift to allocate and release hosts as necessary, according to my configurations and limits.
+
+### Goals
+
+- Enable OpenShift to manage dedicated AWS hosts.
+
+### Non-Goals
+
+
+## Proposal
+
+
+### Workflow Description
+
+### API Extensions
+
+Add fields for host configurations and limits.
+
+### Topology Considerations
+
+
+#### Hypershift / Hosted Control Planes
+
+#### Standalone Clusters
+
+#### Single-node Deployments or MicroShift
+
+### Implementation Details/Notes/Constraints
+
+
+### Risks and Mitigations
+
+
+### Drawbacks
+
+
+## Alternatives (Not Implemented)
+
+
+## Open Questions [optional]
+
+## Test Plan
+
+## Graduation Criteria
+
+### Dev Preview -> Tech Preview
+
+- Ability to utilize the enhancement end to end
+- End user documentation, relative API stability
+- Sufficient test coverage
+- Gather feedback from users rather than just developers
+- Enumerate service level indicators (SLIs), expose SLIs as metrics
+- Write symptoms-based alerts for the component(s)
+
+### Tech Preview -> GA
+
+- More testing (upgrade, downgrade, scale)
+- Sufficient time for feedback
+- Available by default
+- Backhaul SLI telemetry
+- Document SLOs for the component
+- Conduct load testing
+- User facing documentation created in [openshift-docs](https://github.com/openshift/openshift-docs/)
+
+**For non-optional features moving to GA, the graduation criteria must include
+end to end tests.**
+
+### Removing a deprecated feature
+
+- Announce deprecation and support policy of the existing feature
+- Deprecate the feature
+
+## Upgrade / Downgrade Strategy
+
+N/A
+
+## Version Skew Strategy
+
+N/A
+
+## Infrastructure Needed
+
+- Dedicated host(s) for unit testing, e2e, and development purposes.
