title: Google cloud pub/sub integration with Standard java environment
body: <p>I am new to Google cloud platform and is working on developing Google app engine app in standard Java environment. For some of the part, I require using Google cloud pub/sub. Looking at the resources available, I feel that pub/sub can only be integrated in the flexible environment. Can someone please tell if it is possible to integrate pub/sub in the standard environment and if yes then how? </p>
