Abstract
A method for managing communications for a group of servers is disclosed. A processor sends requests to the group of servers for connection information for generating a set of mappings for a load balancer of the group of servers to replace another set of mappings for another load balancer of the group of servers. Responsive to receiving a communication from a client device for the group of servers, the processor determines whether a route to a server in the group of servers can be identified from the set of mappings for the load balancer. If the route cannot be identified from the set of mappings for the load balancer, the processor forwards the communication to a sub-group of the group of servers that have not yet responded to the requests for connection information for generating the set of mapping so that only the one correct server responds.
