 ## Pros and Cons
 
+What works well and what doesn't?
+
 ### Pros
 
 - Simple model, one VM, one compose file per application.
-- Traefik automates TLS and routing with minimal boilerplate.
+- Easy to deploy, great to test an application.
-- Everything declarative enough to rebuild quickly from the repo.
+- Central location for the configurations.
-- Easy to debug: logs and Compose files are local and transparent.
 
 ### Cons
 
-- Manual updates don’t scale as the app count grows.
 - Single Docker VM is a single point of failure.
-- Secrets in .env are convenient but basic; rotation and audit are manual.
+- Manual updates don’t scale as the app count grows.
-- No built‑in rollbacks beyond “change the tag back and redeploy.”
+- Having to declare the URL on Caddy is boring.
+- Hard to follow what is up, and what is not.
+- Secrets in .env are convenient but basic.
+- No fast way to rollback.
+- Operations on the VM are critical.
