Service Dependencies

On Clever Cloud, each application depends on one or more backing add-ons. Each add-on exposes configuration, which allows the user to choose which add-on link to an application.

In a micro services architecture, backing services can be add-ons or other applications. Clever Cloud allows you to declare the dependencies between applications in the same way you can declare a dependency from an application to an add-on.

Clever Cloud allows to declare the topology of your micro services graph by letting you link applications in the same way you can link add-ons.

To link an application to another, go to the “Service Dependencies” tab and add the applications you depend on.

Exposed configuration

Each application can expose configuration to be used by other applications. For instance an API can expose its URL and credentials to access it. The exposed configuration will be injected in the dependent applications' environment.

Redeploy on configuration update

When an application updates its exposed configuration, all applications depending on it are automatically redeployed.
