Cross-Domain Telemetry Architecture: Real-Time Metrics in the Computing Continuum

Abstract

The growing importance of cross-domain collaboration to meet high demand and diverse requirements in service deployments has highlighted the need for robust Continuum Computing solutions. This approach seamlessly integrates computing resources across Cloud and Edge Computing, and beyond, to optimize resource usage and service delivery, even for organizations with limited resources. However, retrieving, sharing, and properly managing metrics about resources acquired across the continuum poses significant challenges. In this regard, telemetry, involving the automated collection and transmission of data, can be enhanced to become a pivotal technology for monitoring in distributed computing. This paper presents the design and implementation of a telemetry-based solution for multi- domain and cross-domain environments, applicable to existing distributed continuum frameworks. The solution facilitates the gathering, analysis, storage, and export of telemetry data across the continuum, while also considering security and privacy to ensure that data metrics are only available to service owners, regardless of the deployment location across the continuum. The solution is being integrated within the FLUIDOS framework as the Telemetry Service component. In the near future, it is expected that implementation results will be validated.
