An improved lookup service is provided that allows for the dynamic addition and deletion of services. This lookup service allows for the addition and deletion of services automatically, without user intervention. As a result, clients of the lookup service may continue using the lookup service and its associated services while the updates occur. Additionally, the lookup service provides a notification mechanism that can be used by clients to receive a notification when the lookup service is updated. By receiving such a notification, clients can avoid attempting to access a service that is no longer available and can make use of new services as soon as they are added to the lookup service.

Accessing data includes determining if the data is provided on a local group of servers or on an external group of servers. If the data is provided on a local group of servers, a storage server is used to access the data. If the data is provided on an external group of servers, a proxy server is used to access the data. The proxy server interacts with an entity accessing the data in a manner that is substantially similar to interaction between the entity and the storage server. Using the proxy server may include initially providing an account id and a password. Following providing an account id and a password, using the proxy server may include using an account id and a shared secret. Using the proxy server may include using RSA ID tokens or cryptographic certificates.
