Practical solutions for resilience in SlapOS

SlapOS is an open source operating system for distributed cloud computing based on the motto “everything is a process”. SlapOS combines grid computing and Enterprise Resource Planning (ERP) to provide Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS) through a simple, unified API which one can learn in a matter of minutes. SlapOS opens new perspectives for research in the area of resilience and security on the Cloud. In this paper we address the question of the lack of resiliency at current IaaS providers and we show how the combination of a simple leader election algorithm and a resource and monitoring system may help in the SlapOS cloud system for solving this issue. The approach exhibits technical and research directions for more elaborated studies.
