each pod comprises a strongly connected discrete set of the plurality of physical resources in the zone, the physical resources in each pod including one or more compute servers, one or more storage servers, and one or more routing servers connected together by one or more pod-level layer-2 network switches;
establishing at least one data network from the distributed networking resources, the at least one data network connecting, and configured for routing traffic to, the plurality of pods from at least one customer;
establishing at least one management server cluster comprising a plurality of management servers;
establishing at least one management network from the distributed networking resources, the at least one management network connecting one of the plurality of management servers to one of the plurality of zones, and connecting the compute and storage resources partitioned within the pod;
establishing a plurality of units of virtual resources by apportioning selected of the physical resources within one or more of the plurality of pods to each of the plurality of units, wherein the apportioned physical resources may be shared between two or more of the plurality of units of virtual resources; and
wherein each management server is configured for allocating one or more of the plurality of units of virtual resources to an account associated with the at least one customer; and
wherein the compute servers of a pod execute a multitenant hypervisor, and the storage servers of the pod present virtual disks to the compute servers, the virtual disks being visible to the multitenant hypervisor as networked file systems or as block devices and being presented as locally attached storage to virtual machines of the compute servers.

Abstract
A scalable cloud infrastructure serves two or more customers, where each customer is associated with at least one unit of virtual resources. The virtual resources are established by apportioning physical resources in the cloud infrastructure that are partitioned into pods within one or more zones in a scalable manner. Each pod comprises a strongly connected discrete set of physical resources in a zone. Additionally, the cloud infrastructure establishes one or more management server clusters each comprising one or more management servers. Each management server is configured for allocating the units of virtual resources to an account associated with each customer. The traffic from two or more customer accounts within the scalable cloud infrastructure is isolated and segmented.
