Load-balancing establishment of connections among groups of connector servers

A method of load-balancing connection establishment, the method comprising:

• assigning a plurality of connector servers that are included in a public computer network among a plurality of groups, each group including one or more connector servers of the plurality of connector servers;
• receiving a connection request from a connector client that is included in a private computer network, the connection request requesting establishment of a connection between the connector client and one of the plurality of connector servers in the public computer network, which is external to the private computer network;
• determining a number of connections between the private computer network and each group;
• selecting an identified group from the plurality of groups to receive the connection request based at least in part on a number of connections between the private computer network and the identified group being less than or equal to a number of connections between the private computer network and each other group;
• and
• providing the connection request toward the identified group, which enables establishment of the connection between the connector client and a connector server in the identified group, based at least in part on selecting the identified group from the plurality of groups.

A computer program product comprising a computer-readable storage medium having instructions recorded thereon for enabling a processor-based system to perform operations, the operations comprising:

• load-balance establishment of a plurality of connections among a plurality of groups, each group including one or more connector servers of a plurality of connector servers that are included in a public computer network, by performing the following:
• receive a connection request from a connector client that is included in a private computer network, the connection request requesting establishment of a connection between the connector client and one of the plurality of connector servers in the public computer network, which is external to the private computer network;
• determine a number of connections between the private computer network and each group;
• select an identified group from the plurality of groups to receive the connection request based at least in part on a number of connections between the private computer network and the identified group being less than or equal to a number of connections between the private computer network and each other group;
• and
• provide the connection request toward the identified group, which enables establishment of the connection between the connector client and a connector server in the identified group, based at least in part on the identified group being selected from the plurality of groups.
