The Access configuration page sets up how a microservice can be accessed. Microservices are accessed with HTTP using a RESTful protocol.

The Url parameter is the root url where this microservice can be accessed within its network. You may consider this an internal url for the purposes of network security. It is used by each microservice in an Application.

The Alternate Url parameter is used only by the Control Panel and may be used to access the Application from outside the network. It will typically be an external ip address if it is specified.

By convention, ports within Arch start at 50001 and increment by 1 for each microservice in a certain logical order. Port 50000 is reserved for the Control Panel. This facilitates having multiple microservice installations on the same computer, such as with all-in-one deployments.

The Client Api Key is used to authorize the microservice as client of the Application Api. It is ignored when the microservice being configured is the Application Api itself.

The Envelope Password is used to encrypt communications to this microservice. All messages are wrapped in an envelope which is secured with this password. Clients of this microservice must use this password to communicate with the microservice.
