A company is designing a new cloud-native application that needs to store frequently accessed user profile data, session information, and real-time analytics data. This data requires low-latency access and high throughput. Which storage type is MOST suitable for this workload?
- AObject Storage
- BBlock Storage
- CArchive Storage
- DFile Storage
Show answer & explanationAnswer & explanation
Correct answer: B. Block Storage
Block storage provides low-latency, high-performance access suitable for transactional databases, user profile data, and other applications requiring fast read/write operations.
Why the other options are wrong
- A. Object storage is highly scalable and cost-effective but typically has higher latency and is not optimized for frequent, low-latency updates required by transactional data.
- C. Archive storage is for long-term, infrequently accessed data and is not suitable for frequently accessed, real-time data due to high retrieval latency.
- D. File storage is suitable for shared network drives and hierarchical data, but not typically the best choice for high-throughput, low-latency transactional data.
Block Storage
A storage type that treats data as fixed-size blocks, each with a unique address, allowing for raw, high-performance access directly to storage volumes.
- Optimized for databases and high-performance applications.
- Provides low-latency access.
- Often presented as a virtual hard drive to a server.
