The Survival Analysis of Three-Tier Architecture Based Cloud Computing System

Cloud computing aims to replace the position of the computing resources over the internet to decrease the expenses of management and maintenance of hardware and software resources, and computing resources are provided to cloud customer on-demand over the internet as a flexible form of service. In some scenario, where application software is not designed with auto-scaling, in such case a redundant system required. The redundant system also required for failover and recovery purpose. The present paper, we have studied the survival probability of a cloud computing system based on three-tier redundant architecture. We have also investigated in this work the importance of component resources in use to build three-tier cloud computing system
