+# Roadmap
+
+I am planning to implement the following features in the future.
+
+
+## HA - High Availability
+
+Support Failover-Mode (secondary ip address) as in official DLS.
+
+**Note**: There is no Load-Balancing / Round-Robin HA Mode supported! If you want to use that, consider to use 
+Docker-Swarm with shared/cluster database (e.g. postgres).
+
+*See [ha branch](https://git.collinwebdesigns.de/oscar.krause/fastapi-dls/-/tree/ha) for current status.*
+
+
+## UI - User Interface
+
+Add a user interface to manage origins and leases.
+
+*See [ui branch](https://git.collinwebdesigns.de/oscar.krause/fastapi-dls/-/tree/ui) for current status.*
+
+
+## Config Database
+
+Instead of using environment variables, configuration files and manually create certificates, store configs and
+certificates in database (like origins and leases). Also, there should be provided a startup assistant to prefill 
+required attributes and create instance-certificates. This is more user-friendly and should improve fist setup.
