The correct answer is C. Create a Cloud Filestore instance and mount it in each instance.. Filestore is fully managed network attached storage and it scales to 100s of TBs for high- performance workloads. Gcsfuse is a user-space file system for interacting with Google Cloud Storage.

Question

You need to deploy a stateful workload on Google Cloud. The workload can scale horizontally, but each instance needs to read and write to the same POSIX filesystem. At high load, the stateful workload needs to support up to 100 MB/s of writes. What should you do?

Options

AUse a persistent disk for each instance.
BUse a regional persistent disk for each instance.
CCreate a Cloud Filestore instance and mount it in each instance.

Explanation

Filestore is fully managed network attached storage and it scales to 100s of TBs for high- performance workloads. Gcsfuse is a user-space file system for interacting with Google Cloud Storage. As with the other access methods, Cloud Storage does not support concurrency and locking. For example, if multiple Cloud Storage FUSE clients are writing to the same file, the last https://cloud.google.com/storage/docs/gcs-fuse
