6. Architectural Modules

In this chapter, you’ll learn about architectural modules.

What is an Architectural Module?#

An architectural module implements features and mechanisms related to the Medusa application’s architecture and infrastructure.

Since modules are interchangeable, you have more control over Medusa’s architecture. For example, you can choose to use Memcached for event handling instead of Redis.

There are different architectural module types including:
