Q: 9

A company is migrating a legacy application that relies on the NFS protocol for shared data access across multiple Linux servers. The data is accessed frequently and is mission-critical. The best Google Cloud storage service that provides a fully managed, scalable, and highly available equivalent to this on-premises file storage is: Cloud Filestore (Enterprise or High Scale) Cloud Bigtable Cloud Storage (Standard) Compute Engine Persistent Disk (Multi-Attach)

Why does Google keep putting Cloud Storage as a distractor in these? Cloud Filestore (Enterprise or High Scale)

Cloud Filestore (Enterprise or High Scale)

Yeah Cloud Filestore (Enterprise or High Scale) is the right pick.

Had something like this in a mock, Cloud Filestore (Enterprise or High Scale) is it.

Makes sense with Cloud Filestore (Enterprise or High Scale) for NFS needs.

Cloud Filestore (Enterprise or High Scale) is the best fit. NFS requirement rules out the others, pretty sure this matches the scenario.

Yeah, Cloud Filestore (Enterprise or High Scale) is what you need for managed NFS in Google Cloud.

Which official guide covers NFS-based storage options in detail for Google Cloud migrations?

Nah, I don't think Cloud Storage (Standard) fits here. The key is NFS protocol support, which only Cloud Filestore (Enterprise or High Scale) actually provides as a managed service. Pretty sure that's what they'd expect.

Cloud Filestore (Enterprise or High Scale)

This is the only one that's fully managed and actually supports NFS directly, which is what legacy apps expect. Cloud Storage looks close but it's object storage, not NFS, so it won't work out of the box for this use case. Pretty sure that's the logic Google wants here but if anyone sees a catch let me know.

Be respectful. No spam.

Correct Answer:

CLOUD FILESTORE (ENTERPRISE OR HIGH SCALE)

Explanation

The question requires a fully managed, scalable, and highly available storage service that supports the NFS protocol for shared access, which is a direct replacement for a legacy on-premises file storage system. Cloud Filestore is Google Cloud's fully managed Network File System (NFS) service, designed specifically for this use case. It allows multiple Linux servers (Compute Engine VMs) to concurrently access a shared file system. The Enterprise and High Scale tiers provide the high availability and performance required for mission-critical applications. Other options are unsuitable: Cloud Storage is object storage, Bigtable is a NoSQL database, and Persistent Disk provides block storage, none of which natively serve the NFS protocol as a managed service.

The first paragraph explicitly states, "Filestore is a fully managed, high-performance file storage service from Google Cloud for applications that require a file system interface and a shared file system for data. Filestore provides a familiar file system experience and is ideal for enterprise applications that depend on NFS."

In the "Choosing a file storage solution" section, it states, "For workloads that require a Network File System (NFS) protocol and shared file access, Filestore is an effective storage option."

3. Google Cloud Documentation, "Cloud Storage products". This page provides a comparison table of Google's storage services. It categorizes Filestore as "File storage" with the primary access method being "NFSv3" and the use case as "Managed network file share." This clearly distinguishes it from Persistent Disk (Block storage), Cloud Storage (Object storage), and Cloud Bigtable (NoSQL database).
