Your team runs an online transaction-processing (OLTP) workload on Compute Engine VMs. The database requires very low latency and up to 300 000 IOPS during seasonal peaks. The data footprint is only 1 TB, and you want to minimize block-storage cost while still meeting the performance target. What should you do?
Run the workload on Spot VMs with Local SSD to obtain higher transient IOPS at lower cost.
Stripe four 256 GB Zonal SSD Persistent Disks in a RAID-0 array on the VM.
Use a Regional Persistent Disk to double the read IOPS without increasing capacity.
Attach a 1 TB Hyperdisk Extreme volume and provision 300 000 IOPS in its performance settings.
Hyperdisk Extreme lets you provision IOPS and throughput separately from disk size. By attaching a 1 TB Hyperdisk Extreme volume and setting the performance slider to 300 000 IOPS, you meet the peak requirement without paying for unused capacity. Regional Persistent Disk adds availability but not extra IOPS. Striping several smaller SSD Persistent Disks would force over-provisioning of capacity to reach similar performance. Local SSD on Spot VMs can offer high throughput but has no durability and unpredictable availability, making it unsuitable for a stateful OLTP database.
