A DNS proxy may tag DNS requests from a virtual network with a separating identifier, such as a virtual network ID, before forwarding them to a shared DNS server. This can allow each virtual network to have its own namespace and avoid naming conflicts. The shared DNS server can examine the tagged DNS requests to respond to the DNS requests using the local namespace as identified by the separating identifier.

Shared multi-tenant domain name system (DNS) server for virtual networks

Techniques are described herein that are capable of forwarding a current request based on, at least in part, previous request(s). For instance, the current request may be received at a first forwarding server from a sending server via a network. The first forwarding server may determine that a second forwarding server is associated with (e.g., receives, causes to be forwarded, or responds to) previous request(s) from the sending system. The first forwarding server may cause the current request to be forwarded to an endpoint based on, at least in part, the previous request(s) being associated with the second forwarding server. For instance, the first forwarding server may cause the current request to be forwarded to the endpoint based on, at least in part, the second forwarding server forwarding the previous request(s) to the endpoint.

Forwarding current request based on, at least in part, previous request(s)

Computerized methods, systems, and computer-storage media for fairly sharing available bandwidth among endpoints (including physical or virtual machines) of a multitenant environment are provided. Initially, a load balancer of the network is programmed to monitor bandwidth used by the endpoints, respectively, and to compare an aggregation of the usage against a network threshold. Also, the load balancer is equipped to dynamically classify the endpoints using the respective monitored bandwidth. Classifying generally involves designating some endpoints as small entities, which individually consume an amount of bandwidth less than an endpoint threshold, and designating other endpoints as large entities, which individually consume an amount of bandwidth greater than the endpoint threshold. Upon the aggregate bandwidth usage overcoming the network threshold, data packets being sent to or transmitted from the large entities are randomly dropped, while data packets being sent to or transmitted from the small entities are unrestrained.
