High Availability Solution over Hybrid Cloud Using Failover Clustering Feature

Cloud computing has proposed a new perspective for provisioning large-scale computing resources by using virtualization technology and a pay-as-you-go cost model. However, cloud computing is subject to failures which emphasize the need to address user's availability. Availability refers to the system uptime and the system capability to operate continuously. Providing highly available services in cloud computing is essential for maintaining customer confidence and satisfaction and preventing revenue losses. Different techniques can be implemented to increase the system availability. This paper demonstrates one way of implementing highly available virtualized network element using Microsoft Windows Server and Microsoft System Center tools.
