Abstract: A system is for use with a data communication network that includes a plurality of servers and a plurality of programs to be run by the servers to provide a plurality of services to devices communicating with the servers over the network. The system comprises a memory that contains computer-readable and computer-executable instructions, and a processor coupled to the memory and configured to read and execute the instructions, the instructions being configured to cause the processor to determine a suggested mapping of the programs to the servers that is different than a current mapping of the programs to the servers.

Abstract: A system for use in a network that includes a plurality of clients and a plurality of servers configured to implement service applications includes at least one interface configured to communicate with the clients and the servers, a memory that contains computer-readable and computer-executable instructions and an access control list with sets of associated client identification and destination service identification, and a processor coupled to the at least one interface and to the memory and configured to read the instructions, the instructions being configured to cause the processor to: analyze an incoming service-access request, received by the at least one interface, for source identification associated with a source of the service-access request and destination service identification associated with an intended destination of the server-access request, the source identification comprising at least one of network source address and a source port number, and the destination service identification comprisin
