I run most of my side projects on a combination of app engine, firebase, and some times even just google spreadsheet. To me Gcloud is also a pretty good bet because they have a very good startup plan ($100k in credits) in case you want to bring any of your projects to the next level. (this is not to say that others have bad services, this is just my personal pref for my own things)
