Typed and compositional microservices in Unison
summary
Unison and Unison Cloud let code be deployed and invoked like local functions: calling deploy : (A -> B) -> ServiceHash AB sends content and dependencies as content-addressed hashes so destinations sync missing objects instead of relying on names or JSON. Demo deploys two HTTP services that call each other, returns a hash-based URL, logs to app.un.cloud, and resolves a query (Cruel Summer → album Lover). Typed durable tables (Song → [Album]) support multi-row transactions and parallel inserts; the demos work live and the cloud is in limited beta.
