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. Operations performed by an instance of one application which affect the state of managed objects are detected and distributed. The technology includes A computer-implemented method detecting operations performed by a first virtual machine on any local instance of a managed object; creating a transaction including the operation and an object identifier referencing the managed object; and forwarding the transaction to all other virtual machines.
