Abstract
In various embodiments, methods and systems for measuring load-balancer responsiveness in a cloud computing infrastructure are provided. A plurality of requests is transmitted to a data center virtual IP (VIP), where the data center VIP is configured to receive inbound traffic for a service. A load-balancing component associated with the VIP distributes the requests to a DIP pool comprised of one or more machines, each associated with a private direct IP (DIP). Each of the machines includes a DIP node-monitoring component including a keep-alive URL for receiving keep-alive probes and a dummy service URL for receiving the plurality of requests. A latency of exclusion or inclusion of a first DIP of a first machine in the DIP pool is determined based on at least some of the requests received by the DIP node-monitoring component from the load-balancing component.
