Anatomy

Diagrams of boxes and arrows describe an idea. These build it. Each piece is the real thing, running: a transformer you can type into, laid out in 3D from its own numbers; a web stack you can overload. The 3D dissections walk through a landmark paper or system component by component, trace every figure to its source, and end with experiments of their own.

Anatomy of Dynamo

Amazon's Highly Available Key-value Store, dissected: a ring of seven nodes laid out in 3D, the paper's Figure 3 lived through by a seeded cluster, and a research desk that tests the model of how stale its reads are.

Dynamo's ring, preference lists, quorums, vector clocks, sloppy quorum, hinted handoff, Merkle trees and gossip as a seeded cluster in 3D, with a research desk that tests the PBS staleness model agai…
