The AWS Panorama application manifest

When you deploy an application, you provide a configuration file called an application manifest. This file defines the application as a graph with nodes and edges. The application manifest is part of the application's source code and is stored in the graphs directory.

Nodes are connected by edges, which specify mappings between nodes' inputs and outputs. The output of one node connects to the input of another, forming a graph.

JSON schema

The format of application manifest and override documents is defined in a JSON schema. You can use the JSON schema to validate your configuration documents before deploying. The JSON schema is available in this guide's GitHub repository.
