We built our recommendation engine for Recent News (https://recent.io/) on Google App Engine in Python. There was some tricky engineering involved in making sure that it would work inside that particular environment, but it's paid off in terms of scalability. We're not worried about Google shutting down App Engine; in fact it's being continuously improved.

The move should be seen as Google transitioning customers to already existing alternative products, especially Google My Maps (formerly Maps Engine Lite) which has come of age and now has most of the important features of Google Maps Engine
A better example would be if Google were to discontinue its paid Google Maps API?

The only companies that don't terminate projects when it it no longer serves a strategic business purpose to support them are companies that instead terminate the projects because they go out of business.
Google is, if anything, unusually good at providing warning and a migration path off a product when they decide to terminate it.
