Extensions
Scalingo for PostgreSQL® addons includes several extensions that are available, but not enabled by default. Most of them can be enabled within seconds.
Please refer to the Managing Extensions page for an exhaustive list of available extensions.
We also have dedicated pages for PostGIS, TimescaleDB®, pgvector and PosgreSQL® Anonymizer.
High Availability
Sandbox and Starter plans are running on a single node, without any redundancy or high availability mechanism. Consequently, we don’t consider them to be highly available. This translates into a lower Service Level Agreement.
Business plans, on their side, include a fully-managed cluster made of:
-
Two (2) PostgreSQL® instances: one primary and one replica, ensuring near real-time replication between the two.
-
Two (2) HAProxy® (one active and one standby) as entrypoint to your cluster private network.
-
Encrypted communications between all instances of the cluster.
The following schema describes the cluster we setup and maintain for each Business plan:
Choosing such a plan drastically lowers the risk of unavailability, be it during a maintenance operation (database upgrade, for example) or because of a platform issue.
