RESTful microservices deployed to AppEngine + Cloud PubSub. With MongoDB for static json assets. And either Firebase or Cloud DataStore for all metadata, config, and application state. Strong isolation between different modules. Set things up right and it will run forever with fixed (or rather, predictable) costs and zero maintenance. I do appreciate how productive GraphQL and frontend frameworks like Gatsby can make developers. Having seen it first hand in hackathons ;)
