A cloud engineer is deploying a new web application that requires high-performance, low-latency storage for its database. The database will be hosted on a virtual machine and needs to support frequent read/write operations with guaranteed IOPS. Which storage type is best suited for this requirement?
- AObject Storage
- BArchive Storage
- CBlock Storage
- DFile Storage
Show answer & explanationAnswer & explanation
Correct answer: C. Block Storage
Block storage provides raw, unformatted storage volumes that can be attached to virtual machines. It offers high performance, low latency, and guaranteed IOPS, making it ideal for databases and other applications requiring direct, fast access to data.
Why the other options are wrong
- A. Object storage is highly scalable and cost-effective for unstructured data, but typically has higher latency than block storage and isn't ideal for databases.
- B. Archive storage is for long-term, infrequently accessed data and is not suitable for active databases due to high latency.
- D. File storage (NFS/SMB) is good for shared access but may not offer the guaranteed IOPS and low latency required for high-performance databases.
Block Storage
A storage architecture that treats data as individual blocks, each with a unique address, providing high performance and low latency.
- Directly attached to compute instances (VMs).
- Ideal for databases, boot volumes, and high-performance applications.
- Offers guaranteed IOPS and throughput.
Memory trick: Block, File, Object: Know your storage options.
