 Azure Stack Hub gets delivered to your data center as an appliance. However, there are still things you need to take care of. So you need to provide enough power and cooling so Azure Stack Hub can run. You need to also provide networking, which is the basic use case for that. So this can be a layer three connection using BGP or static routing. Then you also need to make sure that you can integrate identity. We give you two options. You can use either Azure Active Directory or you can use ADFS to basically log into your existing with your existing identities. Then you also need to make sure that if you have, for example, already tools to monitor in your environment and your infrastructure, you also want to integrate into that. So if you have existing, we provide you with a API which you can use with your existing monitoring tools to get alerts and error messages from the Azure Stack Hub appliance. So you basically can use the same tools as you have been using before.
