What if your Kubernetes pods could start in microseconds instead of seconds, use 64% less memory, and provide stronger security guarantees—all while running the same workloads?
Welcome to the future of cloud-native computing. WebAssembly (WASM) is revolutionizing how we deploy applications on Kubernetes, and in this hands-on 60-minute workshop, you'll master the complete stack from fundamentals to production deployment.
🎯 What You'll Learn
Fundamentals (Deep Dive)
- WebAssembly architecture and WASI (WebAssembly System Interface) internals
- Why WASM achieves 1000x faster cold starts than traditional containers
- Capability-based security model and how it eliminates entire classes of vulnerabilities
Kubernetes Integration Architecture
- How containerd, runwasi, and WASM runtimes work together
- RuntimeClass mechanics for scheduling WASM workloads
- Understanding the complete flow: kubelet → containerd → shim → WASM runtime
Production Tools & Platforms
- SpinKube: The production-ready WASM platform for Kubernetes
- Runtime comparison: Wasmtime, WasmEdge, Spin—when to use which
- Setting up hybrid clusters that run both containers and WASM workloads
Hands-On Demos
- ✅ Deploy your first WASM application to Kubernetes in under 5 minutes
- ✅ Build a custom Rust/Go WASM module and containerize it
- ✅ Compare side-by-side: container vs WASM startup time, memory usage, and density
- ✅ Scale WASM workloads with SpinApp CRDs and observe the performance difference
- ✅ Troubleshoot common issues and implement security best practices
💡 Why This Workshop Matters
WebAssembly on Kubernetes isn't just hype—it's solving real problems:
Serverless & Edge Computing: Sub-millisecond cold starts enable true serverless on your own infrastructure
Cost Optimization: Run 15-20x more workload instances per host
Security: Sandboxed execution with no ambient authority by default
Polyglot Composition: Combine Rust, Go, C++, and more in single deployments with nanosecond inter-component calls
Major organizations are already running WASM in production for payment processing, IoT edge deployments, and high-density multi-tenant systems.
👥 Who Should Attend
This workshop is perfect for:
- Platform Engineers exploring next-gen deployment options
- DevOps Engineers looking to optimize resource utilization
- Kubernetes Administrators wanting to expand runtime capabilities
- Cloud Architects designing serverless/edge computing solutions
- Application Developers interested in WASM compilation targets
Experience Level: Intermediate to Advanced (familiarity with Kubernetes, containers, and basic programming concepts required)
🛠️ Prerequisites
Required
- Laptop with kubectl, Docker/Podman, Helm 3.x installed
