Abstract

An approach to having a shared state from one system to another is to represent data in one system according to service traffic of the other system. For example, by intercepting service traffic associated with a first entity, identifying a data object representing at least a portion of the state of the first entity in the service traffic, and updating a corresponding portion of a shared state data structure in accordance with a value of the data object, the shared state can be maintained outside of the first entity. This process can be extended to maintaining shared state of more than one entity. The service traffic might be e-mail service traffic, database service traffic, or the like. Synchronization commands can be used to initiate at least a portion of the service traffic. The shared state can be used for backups, record-keeping, service migration, disaster recovery, fail-over and/or fault tolerance improvements. In some instances, an application fingerprint can be applied to the service traffic to identify a context of the first data object, with such objects being caching based on context.

Claims

1. A method of representing data of an entity, the method comprising:

intercepting service traffic associated with a first entity;

identifying a data object representing at least a portion of the state of the first entity in the service traffic; and

updating a corresponding portion of a shared state data structure in accordance with a value of the data object.

2. The method of claim 1, further comprising:

intercepting second service traffic associated with a second entity;

identifying a second data object representing at least a portion of the state of the second entity in the second service traffic; and

updating a corresponding portion of a shared state data structure in accordance with a value of the second data object.

3. The method of claim 1, wherein the service traffic is associated with an e-mail service application.

4. The method of claim 1, wherein the service traffic is associated with a database service application.

5. The method of claim 1, further comprising providing a synchronization command to initiate at least a portion of the service traffic.

6. The method of claim 1, further comprising forwarding the shared state information to a target production server.

7. The method of claim 1, further comprising:

applying at least one application fingerprint to the service traffic to identify a context of the first data object; and

caching the first data object based upon the context.

8. The method of claim 1, wherein the shared state information is adapted for use in disaster recovery.

9. The method of claim 1, wherein the shared state information is adapted for use in fault tolerance.

10. The method of claim 1, wherein the shared state information is adapted for use in service migration.
