Evaluation of a Blob Store's Design

We will now evaluate how the design meets our requirements.

Availability

Replication improves availability and fault tolerance. The system maintains four replicas per blob to distribute read traffic and tolerate node failures. The placement strategy spans multiple data centers and regions to reduce the impact of large-scale outages. A monitoring service tracks replica health and triggers re-replication when failures exceed configured thresholds.

For write requests, synchronous replication within the cluster provides strong ...
