Google Associate Cloud EngineerEnsuring successful operation of a cloud solutionMedium
A company is migrating an on-premises application that relies on a network file system (NFS) for shared storage. The application requires low-latency access to shared files for a cluster of Compute Engine instances within the same region. Which Google Cloud storage service should the company choose?
- AFilestore Enterprise
- BCloud SQL
- CCloud Storage Standard
- DPersistent Disk Zonal
Show answer & explanationAnswer & explanation
Correct answer: A. Filestore Enterprise
Filestore is a managed file storage service for applications that require a file system interface and a shared file system. Filestore Enterprise offers higher availability and performance suitable for critical applications requiring shared NFS access in a regional context.
Why the other options are wrong
- B. Cloud SQL is a managed relational database service and is not suitable for providing an NFS file system for shared application data.
- C. Cloud Storage Standard is object storage and does not provide an NFS interface or file system semantics required by the application.
- D. Persistent Disk Zonal provides block storage for a single Compute Engine instance and cannot be shared directly as an NFS volume across multiple instances.
