TITANIUM CLOUD - GUEST HEARTBEAT SDK
===========================================
DESCRIPTION
===========
Titanium Cloud Guest-Client provides a heartbeat service to monitor the
health of guest application(s) within a VM running under WindRiver's
Titanium Cloud. Loss of heartbeat will result in a corrective action
being taken against the VM. The heartbeat interval and corrective action
is specified by the VM.
Titanium Cloud Guest-Client also provides guest application(s) within
a VM running under WindRiver's Titanium Cloud, the ability to receive
notification of and vote to accept or reject actions about to be performed
against the VM. On notifications, the guest application within the VM can
take this opportunity to cleanly shut down or transfer its service to a
peer VM.
