Riak
Dynamo-inspired KV store from Basho. Bet on eventual consistency; lost to operational simplicity elsewhere.
Riak faded because Basho commercial turbulence and Cassandra's momentum starved it of trust. The architecture was sound for certain workloads; the hiring pool was not. Most Riak installs became migration epics with expired support contracts.

Context
Split everything, then pay for the glue
Hyperscale patterns escaped the companies that needed them. Containers unified packaging; Kubernetes became the cloud OS; microservices and NoSQL were sold as defaults. Mobile-first stuck because screens changed. Cargo-cult distributed systems stuck around as invoices. The durable move was packaging and ops maturity — not rewriting every app into a mesh.
