Insights into Multi-Layered Fault Propagation and Analysis in a Cloud Stack

Abstract

Emerging application modernisation efforts are pushing new application services to be built and existing monoliths to be refactored as loosely coupled distributed components (e.g. microservices) for independent scaling and management in cloud. With dynamic operating conditions, component failures, complex component interconnections across the cloud stack, etc., it becomes a challenge to develop effective fault management techniques at the granularity of a multi-layered cloud application service. This paper emphasises on considering faults, errors and failure across the components in different layers of a cloud stack for effective fault management.
