+## Workspace lifecycle:
+
+#### Workspaces Startup phase:
+- Pods (workspace and data sync) are started in parallel
+#### Startup data sync phase:
+- Data flow goes from the persistent volume (rsync server) to the ephemeral volume (rsync client)
+#### Normal workspace usage phase:
+- Containers in the Workspace Pod have full R/W access to the ephemeral volume with restored project sources
+- Container (rsync client) in the Workspace Pod have full R/W access to the persistent volume
+- Data flow goes from rsync client to rsync server periodically by cron job
+#### Workspace Shutdown phase
+- Containers in the Workspace Pod stopped and data flushed to the persistent volume
+
+## Requirements
