MongoDB
Document DB that became a punchline, then a grown-up product. Survived by getting serious about transactions and ops.
MongoDB mutated from "web scale" meme into a real database with transactions and adult ops stories. Early defaults punished newcomers; the company listened because ridicule is expensive. It stuck where flexible documents beat rigid schemas — not everywhere.

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.
