Learn WASMCLOUD with Real Code Examples

Lightweight execution due to WebAssembly

Actors run isolated to prevent side effects

Event-driven architecture enables high throughput

Horizontal scaling by adding hosts to lattice

Minimal cold start latency compared to traditional serverless

Capability-based access control for each actor

Actors run in Wasm sandbox with limited system access

Claims specify exactly what an actor can do

Isolated memory prevents data leaks between actors

Supports secure communication between hosts in lattice

Use wasmCloud CLI logs for runtime monitoring

Integrate with Prometheus/Grafana for metrics

Monitor lattice message throughput

Inspect capability provider health

Profile Wasm module performance

Follow language-specific best practices for actors

Keep modules small and reusable

Define clear capabilities and claims

Test actors independently

Monitor performance and optimize Wasm size
