## Baikal on Ubuntu 24.04 LTS by cloudimg
Baikal is the lightweight, Sabre/DAV-based CalDAV and CardDAV server: host your own calendars and address books and sync them natively with iOS, macOS, Android (DAVx5), Thunderbird and Outlook clients. The cloudimg image runs Baikal behind nginx + PHP-FPM on port 80, stores its database on a dedicated Azure data disk, and generates a unique admin password on the first boot of every VM. Backed by 24/7 expert support.
Dedicated Data Disk
The Baikal application and its database live on a dedicated, independently resizable Azure data disk mounted at /var/www/baikal, separate from the OS disk and re-provisioned with every VM. Snapshot it to back up calendars and contacts.
Secure By Default
DAV endpoints require digest authentication; the admin password is unique per VM and stored in a root-only file. nginx fronts the app so only port 80 is exposed; front it with TLS for production sync clients.
