High durability options for Compute Engine workloads
Durability - how well your data is protected from loss or corruption - is a critical feature of any data storage service. We often receive questions about how to design workloads for durability and what specific durability assumptions a workload can make about Persistent Disk, Google Cloud’s reliable, high-performance block storage for Compute Engine virtual machine instances. To help, we recently published details about how we design Persistent Disk for extraordinary durability.
When we say “designed for”, disk durability represents the probability of data loss, by design, for a typical disk in a typical year using a set of assumptions about:
Specifically, here are all the Persistent Disk types we offer:
