Abstract:
1. A method, comprising: receiving, in a load balancer, a connection request from a client computing device for computing services provided by a number of compute nodes; obtaining a session identifier associated with the connection request; storing the session identifier in a memory coupled to the load balancer; receiving, in the load balancer, a second connection request for a second client computing device; querying said memory to identify which of the compute odes have existing session identifiers stored in said memory; and not sending said second connection request to any compute node that is hosting an existing user session as determined by existing session identifiers stored in said memory, in which, if a user-to-compute node ratio is greater than one-to-one, assigning to at least one of the compute nodes at least two uniquely persistent client computing devices from which the computing nodes will receive connection requests.
