Regions
Watasu runs in the EU today — all apps and add-ons are hosted in data centers in Germany, across multiple availability zones.
App placement
Section titled “App placement”You don’t pick a region when creating an app; everything runs in the EU. The --region flag on watasu create exists for forward-compatibility — as more regions become available, the same flag will let you choose.
Once a process is scaled to two or more replicas, Watasu spreads them across separate zones automatically. See Processes and Scaling.
Add-on placement
Section titled “Add-on placement”Add-on plans encode their own placement:
- Hobby and Standard single-node plans run in one zone.
- Standard replicated plans (PostgreSQL with followers, Valkey with failover replicas, ClickHouse replicas, Redpanda clusters) spread across two zones.
- Premium HA plans add a third zone where the service supports it (for example Valkey Premium’s disaster-recovery replica, Object Storage Premium’s geo-replication).
You don’t configure any of this — it comes with the plan. See Add-on Plans.
Data residency
Section titled “Data residency”All customer data — app images, databases, backups, logs, metrics, traces, and object storage — stays within the EU.
