A company is migrating its legacy application to a cloud environment. The application requires a file system that can be shared and accessed concurrently by multiple virtual machines, similar to a traditional network-attached storage (NAS) device. Which cloud storage type would best meet this requirement?
- AObject Storage
- BBlock Storage
- CArchive Storage
- DFile Storage
Show answer & explanationAnswer & explanation
Correct answer: D. File Storage
File storage is designed for shared access among multiple computing instances using standard file protocols like NFS or SMB, directly mirroring the functionality of a traditional NAS. This makes it ideal for applications requiring a shared file system.
Why the other options are wrong
- A. Object storage is highly scalable but typically accessed via APIs and is not designed for shared file system access by multiple VMs.
- B. Block storage is presented as raw disks to a single VM and is not inherently shareable across multiple instances as a file system.
- C. Archive storage is for long-term, infrequently accessed data and is not suitable for active, shared application data.
File Storage
A cloud storage type that organizes data in a hierarchical file and folder structure, accessible via network file protocols like NFS or SMB, allowing multiple computing instances to share data.
- Shared access for multiple VMs.
- Uses standard file protocols (NFS, SMB).
- Acts like a traditional NAS.
