Abstract

Cloud computing is an emerging computing technology that provides users with the capabilities of it as a service and allows access to these services on the internet without having specialized information or controlling infrastructure. Fault is the one of the biggest challenges in making a system fault tolerant. To reduce the impact of failure on the system and application execution ,failures should be anticipated and proactively handled. Fault tolerance is used to predict the failures and take a proper action before failure occurs. Cloud virtualized system architecture using Haproxy has been proposed. In the proposed system automatic fault tolerance has been implemented. The results shows that the proposed system can deal with various software faults for server applications in a cloud virtualized environment.
