UnFaaSener - Latency and Cost Aware Offloading of Functions from Serverless Platforms

Explore a 22-minute conference talk from USENIX ATC '23 that introduces UnFaaSener, a lightweight framework designed to reduce costs for serverless users. Learn how this innovative system enables the offloading of functions to non-serverless compute resources such as VMs, on-premise servers, or personal computers. Discover the framework's asynchronous scheduler, which optimizes offloading decisions by considering factors like resource availability, latency, cost components, application structure, and QoS expectations. Understand how UnFaaSener supports partial offloading at the function level and implements design choices for confidence and adaptiveness. Examine the system's effectiveness across various serverless application structures, with potential cost savings of up to 89.8% in experimental scenarios. Gain insights into how UnFaaSener operates without requiring changes to existing serverless platforms, utilizing pub/sub services to connect serverless applications with offloading hosts.
