Node is fine for the frontend -- I'd go with React and React Native personally -- but between NPM issues and a general cowboyishness, I wouldn't go near it on the server-side. Backend/API layer would be one or more of Ruby, Python, or Java, depending on what my team felt comfortable with. Large, mature communities, healthy ecosystems, overall decent tooling, good support for testing and deployment automation. Nothing Microsoft. Not going down that road again if I can help it. AWS hands-down. Google tends to have this pathological distaste towards providing support for their customers, and I don't trust them to not just shutter any of their non-core products randomly one day. I am very sold on GraphQL or Protobufs as the interchange format over REST. Databases, hard to go wrong with PostgreSQL. Redis and Memcache for caching.
