 to improve server performance considering the demand of clients, will greatly offer robust fault tolerance, while enhancing performance at large. This paper developed, and analysed the performance of a core layer network simulation which hosts a typical http web service while outlining the advantages of load balancing service. This reflects in the throughput response of a two case scenario: Cloud DCN failure recovery and Cloud DCN No_ failure recovery in a carefully design cloud datacenter setup. From the results of this study, it was observed that the former yielded 99% throughput index while the later offered 97% throughput index. The 3% differential accounts for occasional server downtimes. Consequently, this paper argues that in a data intensive network, any load balancing service will allow load sharing of traffic from access layer endpoints within a common subnet through redundant default gateways, while also providing failure protection. This will offer an additional improvement in a proposed Enterprise Energy Tracking Analytics Cloud Portal (EETACP) in our future work.&picture=http://www.aascit.org/aascit/decorators/img/journal/901.jpg)

In cloud data centre designs, as a result of high density traffic transactions, introducing a gateway load balancer (GLB) to improve server performance considering the demand of clients, will greatly offer robust fault tolerance, while enhancing performance at large. This paper developed, and analysed the performance of a core layer network simulation which hosts a typical http web service while outlining the advantages of load balancing service. This reflects in the throughput response of a two case scenario: Cloud DCN failure recovery and Cloud DCN No_ failure recovery in a carefully design cloud datacenter setup. From the results of this study, it was observed that the former yielded 99% throughput index while the later offered 97% throughput index. The 3% differential accounts for occasional server downtimes. Consequently, this paper argues that in a data intensive network, any load balancing service will allow load sharing of traffic from access layer endpoints within a common subnet through redundant default gateways, while also providing failure protection. This will offer an additional improvement in a proposed Enterprise Energy Tracking Analytics Cloud Portal (EETACP) in our future work.
