MySQL host classes
The host class determines the computing power allocated for each host in a cluster. When you change the host class for a cluster, all existing hosts change to match it.
The available storage size does not depend on the host class. For storage limitations, see Quotas and limits in Managed Service for MySQL.
Available host classes
Hosts in Managed Service for MySQL clusters are deployed on Compute Cloud VMs. You can create these VMs on any platforms Compute Cloud supports. See Platforms for a detailed description.
The full list of possible host configurations on each platform is provided below.
Configuration types:
- s3: Standard configuration, with 4:1 RAM GB to vCPU ratio.
- m3: Configuration with an increased RAM GB to vCPU ratio (8:1). These configurations may be useful for clusters with higher cache requirements.
- c3: Configurations with a reduced RAM GB to vCPU ratio (2:1). These configurations may be useful for clusters with higher processor performance requirements.
