A server and method of its operation adapt the number of server applications within the server. The server is connected to a computer network. The server comprises one or more active server applications, a load detector, an inactive additional server application and an allocator. The load detector, which may be part of a load balancer, is connected to the one or more server applications and the computer network. The allocator is connected to the load detector and the additional server application. The allocator causes the additional server application to activate in response to a load condition. The method measures a load on the server, detects when the load exceeds a threshold and, in response thereto, activates an additional server application on the server. Optionally, the method also detects when the load is less than a deactivation threshold, and in response thereto, deactivates the additional server application. Also disclosed is a system comprising a plurality of computers, one or more connections to one or more servers, and a module. Each of the computers is capable of hosting a server application. The module is connected to the: computers and the connection(s). The module receives a request for an additional server application from one of the servers. Such a request may, for example, be generated when the server is experiencing a surge. In response to the request, the module activates the server application on one or more of the computers so as to support the requesting server.
