Trial broker
When setting up your account, one of the trial brokers is usually already deployed. You can book one cloud hosted trial broker and one on-premises broker per account.
A trial broker can simply be booked from the project overview by clicking on one of the remaining trial broker options. There is nothing to configure. If you book an on-premises broker, you have to install it before using it. In general, you have one option left, as one trial broker is installed after creating your account. So you will see one option like below to install a trial broker.
Click on "Start Trial" to initiate the booking process. There is no configuration or payment necessary.

On-Premises Trial Broker
