Mobile Hub

Mobile Hub orchestrates multiple services to create an AWS backend for mobile and web applications.
Each project in Mobile Hub has one backend made up of configurable features, plus one or more applications.
Features include Analytics, Cloud Logic, Conversational Bots, Hosting and Streaming, NoSQL Database, User Data Storage and User Sign-In. Each feature uses one or two services to deliver a chunk of functionality.
Services used include API Gateway, CloudFront, Cognito, Device Farm, DynamoDB, Lambda, Lex, Pinpoint and S3.
Application SDKs exist for Android (Java), iOS (Swift), Web (JS) and React Native (JS). There is also a CLI for JavaScript applications.

The Mobile Hub console has starter kits and tutorials for various app platforms.
The CLI allows local development of Lambda code (JS by default) with awsmobile {pull|push} commands, to sync from cloud to folder, and back again.
Mobile Hub itself is free, but each of the services has its own pricing model.

🔸The Cloud API feature allows importing an existing Lambda function instead of defining a new one, but there are some rough edges with the CLI. Check the GitHub issues.
❗Mobile Hub uses CloudFormation under the covers, and gets confused when a service is changed outside of the Mobile Hub console.
