Load balancing and failover of gateway devices

A computer data product containing encoded, non-transient data representing instructions for a programmable computing system that when read and executed by the computing system implements a method for assigning communication transaction handling to a gateway, the method comprising:

• receiving a request for a license from a computing device at a control gateway within a group of gateway devices including a plurality of gateway devices configured to support communication of cryptographically split data;
• assigning communications from the computing device to one of the plurality of gateway devices based on a load balancing algorithm;
• and
• routing the communication request to the assigned gateway device;
• wherein the cryptographically splitting data utilize a plurality of encryption keys to create a plurality of separate community of interest data sets in which the primary write requests and corresponding plurality of secondary write request are members of the community of interest associated with the one of the plurality of encryption keys used in the write requests.

A computer data product containing encoded, non-transient data representing instructions for a programmable computing system that when read and executed by the computing system implements a method for handling failover from a failed gateway device in a group including a plurality of gateway devices, the method comprising:

• determining the existence of a failed gateway device within the group of gateway devices, each of the gateway devices configured to support communication of cryptographically split data;
• determining whether the failed gateway device is a control gateway device for the group of gateway devices;
• and
• upon determining that the failed device is a control gateway device:
• assigning a remaining gateway device in the group as a new control gateway device;
• notifying network resources to communicate with the new control gateway device;
• notifying the other remaining gateway devices in the group of the identity of the new control gateway device;
• wherein the cryptographically splitting data utilize a plurality of encryption keys to create a plurality of separate community of interest data sets in which the primary write requests and corresponding plurality of secondary write request are members of the community of interest associated with the one of the plurality of encryption keys used in the write requests.
