The Lattice framework allows endpoints to be categorized along dimensions like availability zones and software versions, enabling precise failure simulation as shown in the README's two-dimensional compartmentalization examples.

ShuffleShard assigns multiple endpoints per identifier (e.g., user) to minimize overlap, reducing impact during traffic faults to 1/(N choose K), which dramatically limits service-wide outages.

RubberTree automatically converts Lattices and ShuffleShards into weighted Route 53 DNS failover setups with standby records, handling complex configurations like zero-weighted branches for health-based routing.

AnswerSet generates Route 53 record sets with chained ALIASes that depend on multiple health checks, ensuring endpoint discovery only when all associated checks pass, as detailed in the DNS chain example.
