Abstract: A system for providing a mapping service for distributed data storage systems includes a plurality of computing devices configured to implement a service provider network. The service provider network includes a plurality of endpoints corresponding to a plurality of data servers. Each data server of the plurality of data servers is configured to receive, from a client, a request for client data stored at the plurality of data servers and send, to a mapping service, a mapping request. The data server receives, from the mapping service, a list of a subset of the plurality of data servers, where each data server of the subset stores at least a portion of the client data. The data server generates a response to the client data request including a data portion and a server identifier portion and sends the generated response to the client.

Abstract: A service provider receives a request to obtain a text-based transmission. In response to the request, the service provider generates an identifier corresponding to the request and, based at least in part on the identifier and text to be included in the transmission, determines a set of textual transformations to associate with the identifier. The service provider modifies the text in accordance with the set of textual transformations and provides the modified text to the requestor as the text-based transmission.
