GCP Professional Cloud Architect Practice Question
Your team is containerizing a scientific simulation platform on Google Kubernetes Engine. During a run, thousands of pods concurrently read and write millions of small checkpoint files (4-16 KB each) into a shared directory. The data must be visible to all pods immediately, and the simulation controller requires standard POSIX file semantics (open, append, rename). After each run, the entire dataset is deleted. Which Google Cloud storage option best satisfies these performance and access requirements while minimizing operational overhead?
Cloud Storage Standard class accessed through the gcsfuse driver
Filestore High Scale SSD tier
A Cloud Bigtable cluster with one column family per checkpoint and HFile export after completion
Regional Persistent Disks on each node with an rsync sidecar for synchronization
The workload needs a fully managed, POSIX-compliant file system that can be mounted simultaneously by thousands of containers and deliver very high IOPS for small-file access. Filestore High Scale SSD is purpose-built for exactly this pattern, offering tens of GB/s throughput and hundreds of thousands of IOPS with immediate consistency. Cloud Storage classes are object stores lacking shared POSIX semantics. Cloud SQL and Bigtable are databases, not file systems, and using per-node persistent disks with manual synchronization would add complexity and likely bottleneck on I/O.
