Abstract
The serverless technology, introduced for data center operation, represents an attractive technology for latency-sensitive applications operated at the edge, enabling a resource-aware deployment accounting for limited edge computing resources or end-to-end network congestion to the cloud. This paper presents and validates a framework for automated deployment and dynamic reconfiguration of serverless functions at either the edge or cloud. The framework relies on extensive telemetry data retrieved from both the computing and packet-optical network infrastructure and operates on diverse Amazon Web Services technologies, including Greengrass on the edge. Experimental demonstration with a latency-sensitive serverless application is then provided, showing fast dynamic reconfiguration capabilities, e.g., enabling even zero outage time under certain conditions.
