US Patent:

20080046400, Feb 21, 2008
Filed:

Jul 11, 2007
Appl. No.:

11/776143
Inventors:

Justin Shi - Wayne PA, US
Suntian Song - Redmond WA, US
International Classification:

G06F 17/30
US Classification:

707002000, 707E17046
Abstract:

An efficient database cluster system that uses multiple stand-alone database servers with independent datasets to deliver higher processing speed and higher service availability at the same time with zero transaction losses. In one embodiment, a dynamic serializing transaction replication engine with dynamic load balancing for read-only queries is implemented. In another embodiment, a non-stop database resynchronization method that can resynchronize one or more out-of-sync databases without shutting down the cluster automatic database resynchronization process is implemented. In yet another embodiment, an embedded concurrency control language is implemented in the replication engine for precise control of the dynamic serialization engine for optimal processing performance. In yet another embodiment, a zero-downtime gateway failover/failback scheme using a public Internet Protocol (IP) is implemented. In yet another embodiment, a horizontal data partitioning method for load balancing update queries is implemented.

US Patent:

20110179268, Jul 21, 2011
Filed:

Jan 20, 2010
Appl. No.:

12/690429
Inventors:

Clifford P. Strom - Sammamish WA, US
Mark E. Paley - Redmond WA, US
Suntian Song - Redmond WA, US
Assignee:

MICROSOFT CORPORATION - Redmond WA
International Classification:

H04L 29/06
G06F 12/14
H04L 9/32
US Classification:

713156, 713189, 713176, 713168
Abstract:

One or more files of an application are obtained and configured as a virtual storage volume. An application package is generated by encrypting, using a key, the one or more files configured as a virtual storage volume. A license generation module generates a license including both a usage policy for the application and the key. A computing device, to run the application, obtains and attempts to authenticate the application package. If the application package is authenticated, then a license associated with the application package is obtained and at least part of the application package is decrypted using the key in the license. A virtual storage volume that includes the application is mounted, and the application is executed in accordance with the usage policy in the license. However, if the application is not authenticated, then the application is not executed.
