Flavors and performance classes
Currently, we offer six different performance classes.
If your performance class is too small, you need to clone your instance to a new one with a bigger performance class.
Performance Classes
Section titled “Performance Classes”| Description | ID | Max. IOPS | Max. throughput (MB/s) |
|---|---|---|---|
| Performance class 2 | premium-perf2-stackit | 1000 | 100 |
| Performance class 4 | premium-perf4-stackit | 2000 | 150 |
| Performance class 6 | premium-perf6-stackit | 5000 | 200 |
| Performance class 8 | premium-perf8-stackit | 10000 | 250 |
| Performance class 10 | premium-perf10-stackit | 15000 | 300 |
| Performance class 12 | premium-perf12-stackit | 20000 | 350 |
Currently, we offer three types of instances. For each type there is a different set of flavors available.

- CPU and RAM is always per node.
- The system uses up to 15 connections for internal essential processes such as backup, monitoring, etc. These connections will be counted towards the max_connections limit.
