Developer Guide

Page last updated:

This guide provides instructions for deploying, running, and managing apps and services with Pivotal Application Service (PAS).

Note: To learn app deployment concepts, see the Getting Started with VMware Tanzu Application Service tutorial on the VMware Tanzu website.

Overview

Developing, running, and managing apps on PAS may include:

• Deploying and scaling apps with diverse languages, frameworks, and dependencies

• Finding software services in the services marketplace, such as databases, email, or message servers

• Creating your own PAS service based on an external server

• Creating service instances and binding them to your apps

• Streaming app logs to an external log management service

• Troubleshooting app deployment and health


If you do these things, you are a PAS developer, and the contents of this guide are for you.
