Hello Octávio, You are right about the facilities offered by the App Engine. More detail may be gathered from the main reply to the "What is the difference between Google App Engine and Google Compute Engine?" question <https://stackoverflow.com/questions/22697049/what-is-the-difference-between-google-app-engine-and-google-compute-engine> in stackoverflow.
You may choose to experiment by deploying the same app in a compute engine machine with Tomcat. There is already a Tomcat Bitnami stack <https://console.cloud.google.com/launcher/details/bitnami-launchpad/tomcatstack> ready to be deployed from the developers console. If you choose to use this facility, you can ascertain your app works if deployed on an independent Tomcat server, as you intend to do in the end. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
