The Internal Service Bus is not an actual service bus, as it only processes messages on the same application instance. Messages that are sent through the service bus are also immediately received and handled synchronously on the same Redakt instance only. Therefore, it does not support a distributed hosting environment and is only meant to be used for single instance Redakt applications. For a distributed (cloud) deployment, a different service bus implementation must be installed and configured.
The Internal Service Bus module is part of the Redakt core and does not need to be installed separately. The Internal Service Bus module is registered with the IoC container by default if no other service bus has been registered.
The Internal Service Bus does not require any additional configuration.
