+### Working session: Architecture discussion
+
+Attendees: Robert, Valentin, Koen, Kevin
+
+- Robert: NixOps should handle backup creation and restore, since it knows all the details for that
+  - There will be an interface to plug Nix expressions with scripts that can access all the resources
+  - Once should be able to build domain-specific applications around that
+  - Valentin: Backups seem to be morally equivalent to deployments "to a file"
+- Koen walked us through myprotagio.nl
+  - Kevin will share source code with Valentin
+  - It's a role-based-permission and billing UI wrapping PowerDNS, Postfix Admin, and InvoiceNinja
+    - Written in Laravel and Tailwind
+  - To build a UI for deployment we'd primarily need a REST API to a database
+    - Primary work would be to do the architecture and design
+  - Valentin: Maybe we could add just the APIs for the deployment workflows from a completely new service, and connect the front-end to that
+    - Won't have to touch the PHP then
+        - But for the full integration to work one will have to understand the whole system anyway
+          - At that point one may as well keep maintaining it or rewrite it
+      - Koen: The existing thing needs work regardless, and would like to move away from PHP to Python anyway
