US 9,069,791 B2 · Database virtualization

Abstract

Aspects of the subject matter described herein relate database virtualization. In aspects, clusters of database servers may be located at various locations of the Internet. When a client seeks to access a logical database, the client may send a logical server and logical database name in a data structure. These names may be used to find a physical server(s) and database(s) that correspond to the logical database. Once the location is determined, a proxy component is used to intercept and/or forward communications between the client and the physical server(s) and database(s) corresponding to the logical database. Using this system, a client may access data from a logical database without knowing the physical address of the logical user database.

Claims20

Dependent claims

In a computing environment, a system, comprising:

one or more servers operable to host one or more user databases;
a directory service operable to store and use data that associates logical server names with the one or more user databases;
and
one or more gateways operable to receive requests from clients regarding data in the user databases, the requests conveyed in conjunction with logical server names and logical database names, the one or more gateways operable to determine a location of a user database using the directory service based on a logical server name and logical database name, the one or more gateways further operable to act as proxies between the clients and the user databases.

1 more element

A processor implemented method for use at a computer system, the computer system including a gateway, the gateway communicatively connected to one or more servers and to a directory service, the one or more servers hosting one or more user databases, the method for providing data to a client, the method comprising the gateway:

receiving a request for a client, the request regarding data in a user database, the request conveyed in conjunction with a logical server name and a logical database name;
determining a location of a user database using the directory service based on the logical server name and the logical database name, the user database selected from among the one or more user database, the directory service operable to store and use data that associates logical server names with the user databases;
and
acting as a proxy between the client and the user database by:
accessing data in the user database on behalf of the client;
and
providing the data to the client.

4 more elements

A computer program product for use at a computer system, the computer system including a gateway, the gateway communicatively connected to one or more servers and to a directory service, the one or more servers hosting one or more user databases, the computer program product for implementing a method for providing data to a client, the computer program product comprising one or more computer storage devices having stored thereon computer-executable instructions that, when executed by a processor, cause the gateway to perform the method, including the following:

receive a request for a client, the request regarding data in a user database, the request conveyed in conjunction with a logical server name and a logical database name;
determine a location of a user database using the directory service based on the logical server name and the logical database name, the user database selected from among the one or more user database, the directory service operable to store and use data that associates logical server names with the user databases;
and
act as a proxy between the client and the user database by:
accessing data in the user database on behalf of the client;
and
providing the data to the client.
