The breakdown of S3's microservices architecture really highlights why it's been so successful for nearly two decades. What strikes me most is the seperation of concerns—each layer handles a specific responsibility without creating dependencies that would limit scale. The erasure coding approach is particularly clever: it achieves redundancy more efficiently than full replication while maintaining high durability. I'm curious about the metadata partitioning strategy—with 350 trillion objects, the global index must use some sophisticated sharding mechanism to avoid hotspots. Do you know if S3 uses consistent hashing for distributing metadata across partitions?
