-NOTE: The Azure sample app is written in the "non-functional" style (using `@Bean`). The functional style (with just `Function` or `ApplicationContextInitializer`) is is much faster on startup in Azure than the traditional `@Bean` style, so if you don't need `@Beans` (or `@EnableAutoConfiguration`) it's a good choice. Warm starts are not affected.

 The app runs in its own HTTP server if you add `spring-cloud-starter-function-webflux` (it won't work with the MVC starter at the moment because the functional form of the embedded Servlet container hasn't been implemented).  The app also runs just fine in AWS Lambda or Azure Functions, and the improvements in startup time are dramatic.
