Add-ons are a way to add services to your application, for example a database or a caching system, to enrich its features.
An add-on can be shared by different applications to share data between them. It can be a database shared by two or three applications of your infrastructure for example, or they can be independent.
The add-ons offer different plan to adapt to your needs. You can find details about them on the documentation page of the add-on.
Clever Cloud provides multiple add-ons to work with your applications:
