PROVENANCE IN CLOUD COMPUTING SYSTEMS

摘要

A method comprises pairing a virtual machine instance with a virtual agent that is registered with registry in an execution environment. In this regard, upon instantiating the virtual machine and the corresponding virtual agent, the virtual agent monitors for transaction(s), e.g., a specific invoked method, on that execution environment. The virtual agent is also configured for generating an event in response to detecting the transaction. The virtual agent provides a unique signature associated with the event, which identifies the origin of the virtual machine instance. Still further, the virtual agent is configured for forwarding the event to the registry for collating with other events so as to produce composite end-to-end logs of processes in a manner that enables provenance.

1. A method comprising:
pairing a virtual machine instance in a cloud computing environment with a virtual agent, wherein the virtual agent is registered with a registry; detecting a transaction involving the virtual machine that is associated with a business process; generating an event in response to detecting the transaction, where the generated event includes provenance information associated with the virtual machine instance by:
encoding into the event, a signature that uniquely identifies an origin of the virtual machine instance; and forwarding the event to the registry, wherein the forwarded event is collected with other events so as to produce a composite end-to-end log of the business process in a manner that enables provenance of the virtual machines that participate in the business process.
