An in-cloud enterprise resource planning system with high availability and access control authentication

The service-oriented hosts in enterprises like ERP system have always encountered the crucial problem of unexpected down-time or system failure that will cause data loss and system termination. Failover is a challenge issue that it cannot be done successfully between physical hosts. Therefore this paper introduces high availability architecture to build an in-cloud Enterprise Resources Planning together with access control authentication deployed in the virtual machine cluster, which can resolve the problems mentioned above. Access control authentication has been designed in the cloud computing system to prevent the service-oriented hosts form external fraud or intrusion. As a result, the approach proposed in this paper outperforms two well-known benchmark ERP systems, in-house ECC 6.0 and in-cloud ByDesign.
