#The invention will be more fully understood by reference to the following drawings which are for illustrative purposes only:

#FIG. 1 is a block diagram of the core system architecture showing two applications, the interception layer, and the interception database.

#FIG. 2 is a block diagram illustrating installation and running of applications

#Referring more specifically to the drawings, for illustrative purposes the present invention will be described in relation to FIG. 1 through FIG. 10. It will be appreciated that the system and apparatus of the invention may vary as to configuration and as to details of the constituent components, and that the method may vary as to the specific steps and sequence, without departing from the basic concepts as disclosed herein.

#The context in which this invention is described is one or more applications being installed, running and accessing local and remote resources. Without affecting the general case of multiple applications, the following scenarios often depict and describe one or two applications as applicable. Multiple applications are handled in a similar manner.

#FIG. 1 illustrates by way of example embodiment 10 the overall structure of the present invention. The following brief overview illustrates the high-level relationship between the various components; further details on the inner workings and interdependencies are provided in the following sections. FIG. 1. Illustrates by way of example embodiment 10 two applications A 22 and B 26 loaded in memory 14 on a node 12. The interception layers 16, 17, are interposed between the applications 22, 26 and the system libraries 18 and operating system 20. The interception database 28 provides system-wide persistent interception information and configuration information for the isolated environments. The interception layers 16,17 combined with the Interception database 28 provides application isolation 24. System resources, such as CPUs 36, I/O devices 34, Network interfaces 32 and storage 30 are accessed using the operating system. Devices accessing remote resources use some form of transport network 38. By way of example, system networking 32 may use TCP/IP over Ethernet transport, Storage 32 may use Fibre Channel or Ethernet transport, and I/O may use USB. The present invention access and arbitrate resources through the operating system and does not work at the transport level.
