A virtual applications architecture is provided according to the present invention. The architecture includes a topology manager for managing applications across a plurality of members, and a virtual applications manager for defining a plurality of resources comprising the applications. The topology manager communicates with the plurality of members to initiate scaling of the applications associated with the virtual applications manager to the members. The architecture may also include a replication system for deploying the applications to the members.

Methods and systems for synchronizing a configuration of resources across multiple computing devices are described. Associated with the master computing device is a configuration of resources that are desired to be synchronized across the additional computing devices. The master computing device is configured to develop a list that describes aspects of its configuration of resources. Additional computing devices are configured to receive the list that is developed by the master computing device and evaluate the list to determine whether its particular configuration of resources is synchronized with those of the master computing device. If a particular additional computing device's configuration of resources is not synchronized with those of the master computing device, the additional computing device prepares a second list that describes its resource configuration needs and sends the second list to the master computing device. The master computing device receives the second list, evaluates it, and sends data to the corresponding additional computing device for use in synchronizing its configuration of resources.

Methods and systems for synchronizing multiple computing devices

Extensible markup language (XML) methods and systems for synchronizing a configuration of resources across multiple computing devices are described. In the described embodiment, a computer network comprises a master computing device and a plurality of additional computing devices communicatively linked with the master computing device. The master computing device comprises a configuration of resources that are desired to be synchronized across the additional computing devices. The master computing device is configured to develop a XML list that describes aspects of its configuration of resources. Each additional computing device is configured to receive the XML list that is developed by the master computing device and evaluate the XML list to determine whether its particular configuration of resources are synchronized with those of the master computing device. If a particular additional computing device's configuration of resources is not synchronized with those of the master computing device, the additional computing device prepares a second XML list that describes its resource configuration needs and sends the second XML list to the master computing device. The master computing device receives the second XML list, evaluates it, and sends data to the corresponding additional computing device for use in synchronizing its configuration of resources. Each of the additional computing devices can send separate independent XML lists that describe their resource needs and the master computing device is capable of individually responding to each one. In one aspect, the computing devices are computer servers that are configured as Web servers.

A system for generating message headers where previously saved message headers are retrieved from memory when needed to satisfy a message header requirement. Message headers are comprised of segments where each message header segment has a different lifetime. In particular, a file-object response message header includes a header segment containing information linked to the requested file-object. This file-object linked header segment is retrieved when needed from a file-object header cache. A file-object response message header includes other segments such as one containing time-variant global information and time-invariant global information. Building header messages from multiple segments retrieved from their respective cache memories saves significant processing time as compared to generating a new message header each time a header is required by operation of a network server application.
