Azure Stack Hub integrated systems connection models

If you're interested in purchasing an Azure Stack Hub integrated system, you need to understand several datacenter integration considerations for Azure Stack Hub deployment to determine how the system will fit into your datacenter. In addition, you need to decide how you'll integrate Azure Stack Hub into your hybrid cloud environment. This article provides an overview of these major decisions including Azure connection models, identity store options, and billing model options.

If you decide to purchase an integrated system, your original equipment manufacturer (OEM) hardware vendor will help guide you through the planning process in more detail. The OEM hardware vendor also performs the actual deployment.

Choose an Azure Stack Hub deployment connection model

You can choose to deploy Azure Stack Hub either connected to the internet (and to Azure) or disconnected. Deploy connected to Azure to get the most benefit from Azure Stack Hub, including hybrid scenarios between Azure Stack Hub and Azure. This choice defines which options are available for your identity store (Microsoft Entra ID or Active Directory Federation Services) and billing model (pay in advance based billing or capacity-based billing) as summarized in the following diagram and table:

This is a key decision point! Choosing Active Directory Federation Services (AD FS) or Microsoft Entra ID is a one-time decision that you must make at deployment time. You can't change this later without re-deploying the entire system.
