Shameless Plug!
webassembly 101
- Stack-based virtual machine
- Operating System agnostic
- Processor architecture agnostic
- Not just for browsers!
- Works anywhere host/guest agree on contract
wascc
- Write your business logic as a WebAssembly module
- Embraces the actor model
- Secure - actors can only do what signed, embedded JWTs allow
- Flexible - actors and capabilities can be swapped at runtime, different envs, clouds, etc.
A dynamic, elastically scalable WebAssembly host runtime for securely connecting actors and capability providers

why nats?
- HTTP Server and NATS client were first capability providers for waSCC
- It "just works"
- Always the one part of my infrastructure I never worry about
- Can use as substrate for other comms patterns
- One of the most immediately useful CNCF projects
