VLBCoordinator Sample Clauses

VLBCoordinator. VLBCoordinator is used to interact with the EUCALYPTUS cloud. Typica (Google Code, 2008) is a simple API written in Java to access a variety of Amazon Web services such as SQS, EC2, and SimpleDB. Currently, Typica is not able to interact with Eucalyptus-based clouds. I hacked Typica to interact with EUCALYPUTS. VLBCoordinator uses Typica to interact with EUCALYPTUS. The core functions of VLBCoordinator are instantiateVirtualMachine and getVMIP, which are accessible through XML-RPC. Figure 3.3 shows a sequence diagram of a use case in which a user wants to instantiate a virtual machine by providing its virtual machine id. Figure 3.4 shows a sequence diagram of a use case in which the user needs to obtain the IP address of a virtual machine by providing its instance id.
