A cloud customer is migrating a legacy on-premises application that relies on a block-level storage array to a cloud environment. The application requires high-performance, low-latency storage that can be formatted and managed like a physical disk. Which cloud storage type would be most appropriate for this migration?
- AFile Storage
- BObject Storage
- CBlock Storage
- DArchive Storage
Show answer & explanationAnswer & explanation
Correct answer: C. Block Storage
Block storage provides raw, unformatted storage volumes that can be attached to virtual machines and treated like a physical hard drive, offering high performance and low latency suitable for applications requiring direct disk access and control, such as legacy applications migrated from block-level arrays.
Why the other options are wrong
- A. File storage provides shared file systems, which is different from the raw, block-level access required by the legacy application.
- B. Object storage is for unstructured data access via APIs, not suitable for traditional file systems or applications requiring block-level access.
- D. Archive storage is for long-term, infrequently accessed data and is not designed for high-performance, low-latency application use.
Block Storage
Block storage is a type of data storage that stores data in fixed-size blocks, each with a unique address, allowing operating systems to treat them as raw hard drives. It offers high performance and low latency, making it ideal for databases, virtual machines, and transactional workloads.
- Provides raw storage volumes.
- Accessed at the block level, like a physical disk.
- Offers high performance and low latency.
- Suitable for databases, OS volumes, and transactional applications.
