android - Is Google Cloud Messaging Service required for push notifications -

-

I am looking to create an Android app that uses a MySQL database located on a server when in this database If some changes are made, then I need a push notification to be sent to some app users. My question is, is this the necessary Google Cloud Messaging service to implement? This page suggests that Google is also required to use the Developer Console If so, is it possible to export this project in Eclipse? thank you in advanced.
