This document provides an experimental evaluation of the introduction of a resilient ICT infrastructure based on orchestration and distributed computing technologies according to the Cloud/Fog/Edge computing paradigm.

The concept of resilience in the ICT field is analyzed by providing specific examples of metrics and proposing a monitoring platform that helps evaluate the resilience of an orchestrated system in real time.

The report presents experimental evaluations of several ICT architectures with high resilience capacity. A microservices and orchestrated function capable of estimating the state of the power grid is then introduced, with advantages both in terms of performance and resilience.

This function can be integrated into an innovative power measurement monitoring architecture, based on orchestration and the Cloud/Fog/Edge computing paradigm. Synchrophasor data latency and resilience gain are evaluated on a realistic implementation of the architecture.

An analysis of some possible infrastructure failure scenarios, considering the limitations and advantages offered by the various emerging ICT technologies allows to design a self-healing infrastructure capable of minimizing the impacts of ICT failures on energy systems. Architectures based on Cloud/Fog/Edge computing and orchestration solutions make it possible to increase ICT service availability and resilience that represents an essential component for reducing non-operational times of the energy infrastructure.
