1. A computer-implemented method of virtual workload deployment based on computing resource hardware load and associated network hardware load, the computer-implemented method comprising: for each of a plurality of computing resources within one or more data centers onto which a virtual workload can be deployed, determining a computing resource hardware load of the respective computing resource, maintaining network topology information for at least one network fabric of the one or more data centers, and determining, based on network state data for the network fabric, an associated network hardware load of a network device communicatively connected to the respective computing resource; in response to the determining and the maintaining, automatically selecting one or more computing resources of the plurality of computing resources based on evaluating, for each of the plurality of computing resources and by operation of one or more computer processors, a predefined function of both (i) the computing resource hardware load of the respective computing resource and (ii) the associated network hardware load of the network device communicatively connected to the respective computing resource; and deploying the virtual workload onto the automatically selected one or more computing resources, whereafter an indication that the virtual workload is deployed is outputted; wherein the network device comprises at least one of (i) a Top of Rack (ToR) switch that is directly adjacent to the respective computing resource, in a network topology described by the network topology information and (ii) a spine network switch within the network fabric that is communicatively connected to the ToR switch; wherein the associated network hardware load comprises at least one of (i) a measure of Media Access Control (MAC) table entries, (ii) a measure of Virtual Local Area Network (VLAN) availability, (iii) a measure of hardware network route availability, (iv) a measure of bandwidth subscriptions, (v) a measure of feature availability in one of the ToR switch and the spine network switch, (vi) a measure of server uplink subscriptions, and (vii) a measure of fabric link subscriptions.
