Orchestrating WebAssembly modules in the Edge-to-Cloud continuum with Oakestra

The Cloud Computing model is employed in several industrial domains, including smart environments, via IoT and Edge Computing. A view of a continuum of computing is now emerging, where computation is deployed seamlessly from “strong” nodes at the center of the Cloud to “poorer” devices at the edge. This goal is challenged by the heterogeneity of the corresponding infrastructure, threatening performance, security, and portability. WebAssembly is a novel technology that can help address those needs while creating distributed collaborative and orchestrated applications. Oakestra is an open-source orchestration framework that allows creating opportunistic, ephemeral, federated clusters of continuum nodes. We extended Oakestra to support WebAssembly and evaluated it quantitatively using state-of-the-art benchmarks.
