Episode notes
WebAssembly's True Portability
- WebAssembly binaries run unchanged across all architectures, unlike ELF binaries limited to specific OS or hardware.
- This portability reduces months of supporting and testing cursed dependencies across platforms.
WebAssembly Enables High Density
- WebAssembly apps exhibit high density, doing nothing consumes minimal CPU and memory.
- It enables huge efficiency gains over traditional serverless models for cloud cost and infrastructure.
Leverage WebAssembly Security Model
- Utilize WebAssembly's capability-based security to enforce strict runtime access for multi-tenant environments.
- This approach simplifies isolation compared to container-based methods in complex cloud platforms.
