How sustainable is server-side WebAssembly in 2026? Continuous resource usage monitoring with the WasmPulse platform

Marcin Ziółkowski - Orange Innovation Poland

Sustainability is a key objective for cloud and edge infrastructure, particularly in high-scale Telco deployments where energy consumption is a major concern. WebAssembly (Wasm) is positioned as the next efficient execution layer for cloud computing, but it currently lacks the peer-reviewed performance results and continuous monitoring tools to justify large-scale adoption.

This talk fills that gap. We introduce WasmPulse, an open-source benchmarking framework built on the methodology described in an accepted IEEE CCNC 2026 paper. We will provide a deep-dive, data-backed analysis comparing server-side Wasm (AOT/JIT), containers, and bare-metal processes across key sustainability metrics: startup speed, artifact size, network latency, and CPU/Memory usage scaling under high load.

Key Takeaways:

• Hard Data: Quantifying Wasm’s sustainability advantage, including smaller artifact size, faster startup and more stable memory usage compared to containers.
• WASI Focus: Performance numbers for the new WASI Preview 2 and wasi:http standards, showcasing Wasm’s networking evolution.
• Open-Source Tooling: Learn how to use the improved WasmPulse framework for continuous, reproducible performance data generation.
• The results decisively position Wasm as a lightweight, performant, and sustainable foundation for cloud-native Telco platforms.
