What's the difference between Playground, Sandbox, and Production?

You might be deploying on Network Edge today to run through @Charles_Randall's tutorial. While reading up on Network Edge at Developer Platform, then perhaps you're thinking "what's the difference between Playground, Sandbox, and Production?".

In short:

Playground is a test environment to test Equinix APIs, using static data without integrating within the actual API.

Sandbox is a mock test environment to test Equinix APIs, using synthetic data (not production data) to integrate with Equinix APIs before moving to Production.

Production is the live environment.
