ABSTRACT
Today business mostly depends on cloud computing, which brings both opportunities and issues. Cloud datacenters are also getting progressively famous for their adaptability and processing abilities. The capacity to tolerate, remediate and recoup from network failure in a datacenter is basic for building and operating exceptionally accessible cloud services. Accomplishing adaptation to non-critical failure readiness requires a profound comprehension of the network unwavering quality at scale alongside its suggestions on the cloud foundation that runs a datacenter. This chapter covers unwavering reliability attributes of the intra and inter datacenter network by understanding the cloud computing architecture, the outcomes of cloud service failure and resiliency of the datacenter network topologies. An idea of a resilient virtual network's fault-tolerant mechanism, such as DCell, with no single point disruption is presented. Its performance by using distributed fault-tolerant routing protocols to perform near shortest path routing even within the sight of server connection node failure is analyzed.
