Abstract:
Based on the pay-as-you-go strategy, cloud computing platforms are spreading very rapidly. One of the main characteristics of cloud computing is the splitting into many layers. From a technical point of view, most cloud computing platforms exploit virtualization, which implies that they are split into 3 layers: hosts, virtual machines and applications. From an administration point of view, they are split into 2 layers: the cloud provider who manages the hosting center and the customer who manages his application in the cloud. This structuring of cloud makes it difficult to implement effective management policies. This paper focuses on fault tolerance in cloud computing platforms and more precisely on autonomic repair in case of faults. It discusses the implications of this splitting in the implementation of fault tolerance. In most of current approaches, fault tolerance is exclusively handled by the provider or the customer, which leads to partial or inefficient solutions. Solutions, which involve a collaboration between the provider and the customer are much promising. We illustrate this discussion with experiments where exclusive and collaborative fault tolerance solutions are implemented in an autonomic cloud infrastructure that we prototyped.
