Performance Guard monitors load across the Cloud VPS host cluster and rebalances workloads onto hosts with spare capacity. This helps prevent contention from other VMs from slowing down your VM.
Do I need to choose a CPU priority?
The old CPU Priority percentages no longer describe the current Cloud VPS service. Choose the vCPU and RAM allocation your application needs. Performance Guard operates at the host level; it does not automatically increase or decrease your VM's allocated vCPU or RAM.
If your application needs more resources, see Resize CPU and RAM.
What happens if a host fails?
Automatic failover is a separate cluster feature. Affected VMs restart on healthy hardware after a host failure, so there is an interruption while they recover.
See Cloud VPS features for more about Performance Guard and failover.
