How can I integrate ServiceNow data with SAP effectively?

I’m a new ServiceNow Administrator/Developer and a client ask me to develop a solution to integrate the ServiceNow data with SAP or vice versa.

And I have the following concerns:

1.-How can I get an instance in SAP to develop on it and start with the API integration?

2.-Servicenow is a cloud base service and I think that the SAP it’s a desktop software and it start to integrate it on the cloud, right?
