Webhooks
Send events to a microVM that wakes and responds in milliseconds, then shuts down until the next event.
No warm instance waiting for a delivery that may not come; the event itself is what starts the handler.
Between deliveries the handler isn't running. Endpoints that fire a few times a day stop being a standing bill.
When a provider replays a backlog, the service group adds instances in milliseconds and balances across them.
Stripe, GitHub, your own services
Under the hood
The platform features this use case is built on.
The VM only runs while it is actively serving a request.
The service group can add instances in milliseconds to deal with event storms.
Distributes incoming events across the instances in the service group.
