Business-critical applications often require predictable, low-latency I/O and high durability. Provisioned IOPS SSD (io1 or io2) Amazon EBS volumes are specifically engineered for these workloads.
Option C provides consistent, high-performance storage with guaranteed IOPS and low latency. EBS volumes are network-attached and persist independently of the EC2 instance lifecycle, ensuring durability and data protection. Provisioned IOPS volumes are commonly used for databases, transactional systems, and latency-sensitive applications.
Option A (instance store) offers low latency but is ephemeral and loses data on instance stop or failure. Option B is in-memory caching and not durable storage. Option D is optimized for large, sequential workloads and does not provide consistent low latency.
Therefore, C is the correct choice because it delivers the required performance, durability, and reliability for mission-critical applications.
