Datadog published Husky in 2022, a third-generation event store built on commodity object storage with FoundationDB holding the metadata, replacing an architecture backed by local SSDs. What forced the change, what did it buy economically, and what did it cost?

Telemetry is 28% of infrastructure spend on a contract billed per host and per custom metric, with 14 months left on a minimum annual commitment. The team wants to move to a self-hosted stack. Sequence the move under live traffic, and say when the saving actually starts.
