ISC2 Certified Cloud Security Professional (CCSP) Practice Question

Transactional databases need storage that behaves like directly attached disks, supports very low-latency random I/O, and allows the operating system to manage its own file system. Managed block storage volumes supplied by major cloud providers (for example, AWS EBS, Azure Managed Disks or Google Persistent Disk) are engineered for this purpose: they expose virtual block devices to instances, deliver single-digit-millisecond latency, can be provisioned for high IOPS, and include provider-managed encryption at rest plus snapshot functionality. In contrast, object storage is optimized for large, unstructured data with higher latency and does not present a block interface; managed file shares use network file protocols that add latency and may not meet stringent I/O requirements; archival tiers are designed for infrequent access and have retrieval delays, making them unsuitable for active OLTP workloads.
