	System.out.println("Executing Alpha compute.instances().list() server call on " + projectId + "...");
	try {
	InstanceList instances = computeService.instances().list(projectId, zone).execute();
	System.out.println("Total Alpha items: " + (instances.getItems() == null ? 0 : instances.getItems().size()));
