In this section we'll look at using Cloud Foundry, an open-source PaaS from Pivotal, to make short work of managing the application in production.

• we'll demonstrate how to tear an app and associated services down if they already exist
• we'll then push our application to Cloud Foundry, a hosted Platform-as-a-Service
• we'll use ElephantSQL to provision a PostgresSQL database and then bind it to our application. Auto-reconfiguration will take over from there.
• we'll then use Cloud Foundry easy auto-scale features to scale an application up-and-out
• we'll watch Cloud Foundry provide us with auto-healing by invoking the /killme endpoint that we've added to our application and then watching it go from 2/3 instances to 3/3
• we'll demonstrate that we can easily also connect to any of our backing services by going to the run.pivotal.io dashboard or just using the API.
• we'll add application performance monitoring by adding New Relic
• we'll add a hosted logging drain, PaperTrail
• then we'll look at how Cloud Foundry can give us a manifest.yml so that all of our steps need not be repeated.
• we'll also look at how cf oauth-token can give us an access-token that you can plugin to, for example, the Java CF Client API to programatically do everything we've just done.

This example uses H2 and so should run locally. Use mvn spring-boot:run for the demo module or simply run the application in your IDE using public static void main.
