Lucas discussed and demonstrated the wasmCloud v2 concept of "services."
In wasmCloud V2, workloads are composed of many components, which are stateless and invocation-based. Services, however, are stateful, and can act like localhost for your components.
Services can open TCP sockets, enabling them to manage persistent connections, provide connection pooling, proxying, and more. Components within a workload can connect to these services via localhost.
Services are useful for things like managing database connections (e.g., running a PG bouncer), handling large amounts of memory, or maintaining state across multiple invocations.
Maintainers are actively working on services, including development with wash.
