Microservice-based solutions are now widely adopted in many industries, from gaming to IIoT. Different systems are provided to deploy and use serverless microservices at the edge in order to offload backend systems residing in the cloud. However, adopting microservice architecture in a hybrid edge cloud environment also means creating an ad-hoc peer to peer service mesh at the edge. This presentation will explore the impact of full usage of hybrid edge cloud in microservice-based solutions either at the architecture level or management level, by going through solutions where serverless microservices deployed on the extreme edge such as smart phone or smart industrial devices can discover each other and communicate directly and with a backend cloud infrastructure.
