>I think Google’s Zanzibar is also centralized but leverages extreme caching to get lower latencies?
That's correct. In a Zanzibar-like model, you have a global storage, but individual clusters in each datacenter/edge providing consistency-aware caching. This means p99 can be something like 25ms, but p95 or p50 is often FAR lower.
