+# KubeFleet Roadmap
+
+## Project Website
+- Setup the project website
+
+## Support more cluster properties so that user can pick the right cluster for their workload
+- Support node level SKU as properties, e.g. CPU, GPU, Memory, etc 
+  - The application admin can choose clusters that have nodes with H100 GPU.
+  - The application admin can choose clusters that have nodes with 128GB memory.
+- Support network topology
+  - The application admin can choose the clusters with requires infiniband, or 100Gbps network.
+
+## Support scheduling for namespaced resources (heterogeneous namespace)
+- Support independent scheduling policy for namespaced resources
+  - e.g. The application admin can pick one workload in a namespace to cluster A while the other workload in the same namespace to cluster B.
+
+## Dynamic scheduling
+- De-scheduler for the fleet
+  - The de-scheduler would move the workload to the right cluster if the cluster is not the best fit for the workload anymore.
+- Cordon a cluster
+  - The fleet admin can cordon a cluster to move all the workloads off the cluster.
+- Rebalance the workload
+  - The application admin can rebalance the workload to make sure the workload is spread evenly across the clusters.
+
+## Support anti-affinity for workload
+- Support affinity/anti-affinity for their workload.
+    - The application admin can specify that their workload A needs to be placed on the same clusters that workload B runs.
+    - The application admin can specify that their workload A cannot be placed on the same clusters that workload B runs.
+
+## Support Customized health check for workload
+- Support user specified health check for their workload.
+    - The application admin can provide a customized health check for their workload.
+
+## Support Spread mode for workload
+- The application admin can specify a spread mode for their workload.
+    - The move between clusters would follow the max-unavailable/min-available pods rule.
