Application
The constrained Rust process that receives only the handles, routes, secrets,
and network destinations declared in ferrite.json.
Binding
A local handle that grants one application access to one declared service.
Code uses the handle with calls such as ctx.queue("jobs").
Store
Linearizable key-value state with guarded updates.
Transaction
An atomic guarded change across multiple keys. The SDK exposes this through an APE binding.
Stream
An ordered durable sequence read by offset. A topics binding provides multiple named streams.
Queue
Durable leased work with acknowledgement, retry, delayed delivery, and dead-letter handling.
Object Storage
Content-addressed durable objects accessed through a Blob binding.
Function
An isolated application process supervised and scaled by Ferrite.
Route
A public path prefix connected to an API Queue, static content binding, WebSocket flow, or event stream.
Egress
Outbound HTTP performed through a named handle and restricted to declared URL prefixes.
Release
An immutable accepted build of application source.
Environment
A named pointer to a release, such as a production environment or an expiring deployment used before promotion.
Agent-native app
An app that publishes human HTML and machine-usable Markdown, discovery, OpenAPI, MCP, and WebMCP surfaces from the same product contract.
