Applications

At the root of everything are applications. In fn, an application is essentially a grouping of functions with path mappings (routes) to each function. For instance, consider the following URLs for the app called myapp:

http://myapp.com/hello
http://myapp.com/users

This is an app with 2 routes:

1. A mapping of the path /hello to a function called hello
2. A mapping of the path /users to a function called users

Routes

An app consists of 1 or more routes. A route stores the mapping between URL paths and functions (ie: container iamges).

Calls

A call represents an invocation of a function. Every request for a URL as defined in the routes, a call is created. The call_id for each request will show up in all logs and the status of the call, as well as the logs, can be retrieved using the call_id.

Logs

Logs are stored for each call that is made and can be retrieved with the call_id.
