Scalingo for MySQL® Features
In addition to the features common to every database addon, Scalingo includes several features that are specific to our Scalingo for MySQL® offers.
The following table lists these features, with distinguishing values for each class of service. A short description of each feature is also available after the table.
| Feature | Sandbox | Starter | Business |
|---|---|---|---|
| RAM | 512 MB | 512 MB - 32 GB | 1 GB - 32 GB |
| Included Storage | 512 MB | 10 GB - 640 GB | 20 GB - 640 GB |
| Maximum number of connections | 13 | 30 - 1536 | 64 - 1536 |
| Nodes (High Availability) | 1 | 1 | 3 |
| Gateways (High Availability) | 1 | 1 | 2 |
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 InnoDB cluster made of:
-
Three (3) MySQL® nodes implementing MySQL® Group Replication in single-primary mode (one primary, two secondaries hot-standby).
-
Two (2) MySQL® Router instances (one leader and one failover) 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.
