alt Hacker NewsDo such small caps on CPU/RAM mean that multiple customers are sharing the same server? Is there concern for noisy neighbors here, either IOPS or in case another customer's workload grows to take the full available storage on the NVMe? What kind of downtime would be needed to switch to a larger size?
We've engineered in protections from noisy neighbors in both CPU and I/O usage and we do not over-commit resources.
If your or another customer's workload grows and needs to size up we launch three whole new database servers of the appropriate size (whether that's more CPU+RAM, more storage, or both), restore the most recent backups there, catch up on replication, and then orchestrate changing the primary.
Downtime when you resize typically amounts to needing to reconnect i.e. it's negligible.
