/** * Start Instances Action Sample * Starts an instance that uses an Amazon EBS volume as its root device. * Instances that use Amazon EBS volumes as their root devices can be quickly stopped and started. * When an instance is stopped, the compute resources are released and you are not billed for hourly * instance usage. However, your root partition Amazon EBS volume remains, continues to persist your * data, and you are charged for Amazon EBS volume usage. You can restart your instance at any time. * @param Amazon_EC2_Interface $service instance of Amazon_EC2_Interface * @param mixed $request Amazon_EC2_Model_StartInstances or array of parameters */ function invokeStartInstances(Amazon_EC2_Interface $service, $request) { try { $response = $service->startInstances($request); echo "Service Response\n"; echo "=============================================================================\n"; echo " StartInstancesResponse\n"; if ($response->isSetResponseMetadata()) { echo " ResponseMetadata\n"; $responseMetadata = $response->getResponseMetadata(); if ($responseMetadata->isSetRequestId()) { echo " RequestId\n"; echo " " . $responseMetadata->getRequestId() .
