Stateful VM Migration Among Heterogeneous WebAssembly Runtimes for Efficient Edge-cloud Collaborations

Published: 22 April 2024 Publication History

Abstract

WebAssembly (Wasm) has been attracting attention as a common platform for edge computing thanks to its architecture neutrality, sandboxing for security, and lightweight characteristics that fit the requirements for distributed and cooperated processing with heterogeneous compute nodes, which consist of edge devices and clouds. Virtual machine (VM) migration technology enables seamless and flexible workload offloading on edge-cloud collaboration, but unfortunately, VM migration among different Wasm runtimes is complicated since the Wasm standardization does not specify the implementation design of internal runtime very well. Nevertheless, many implementations of Wasm runtime already exist, and each has different characteristics. We therefore aim to implement a stateful VM migration among most of the major Wasm runtimes. In this work, we prototyped a VM migration mechanism between WasmEdge and WAMR to investigate the technical challenges and determine the feasibility of implementing the runtime-neutral VM migration. Our experimental results on heterogenous VM migration demonstrate the value of coexisting multiple runtimes well-suited for each edge and cloud and seamlessly offloading the workloads among them.
