Techniques are described for providing load balancing functionality among multiple computing nodes. In some situations, the provided load balancing functionality includes dynamically scaling a group of multiple computing nodes for which the load balancing is performed, such as to dynamically expand and/or shrink the quantity of computing nodes in the group based on predefined criteria. At least some of the computing nodes of a group may be part of one or more physical computer networks in one or more geographical locations under control of a user or other entity, and at least some of the dynamic scaling of the group may use one or more other computing nodes that are part of a remote computer network (e.g., a virtual computer network provided under the control of a network-accessible service). The defined criteria used for the dynamic scaling may be determined in various manners and based on various factors.
