Abstract
Technology for sharing data among multiple virtual machines in a cluster of virtual machines is disclosed. Each virtual machine identifies 'managed' objects of an instance of an application running at the virtual machine. The managed objects are objects for which state information is to be replicated at the other virtual machines in the cluster on which other instances of the application are running. Operations performed by an instance of one application which affect the state of managed objects are detected and distributed. A computer-implemented method for maintaining consistent object states at different virtual machines includes receiving managed object state information from a first virtual machine including a first instance of an application; creating a representation of each of the managed objects; and responsive to the received information, communicating state information to at least a second virtual machine on which a second instance of the application is running to replicate the state information at the second virtual machine.
