A large enterprise architecture for SharePoint, Dynamics CRM, and Linux web servers hosted on an on-premises datacenter with failover to Azure infrastructure.

This solution is built on the Azure managed services: Traffic Manager, Azure Site Recovery, Azure Active Directory, VPN Gateway, and Virtual Network. These services run in a high-availability environment, patched and supported, allowing you to focus on your solution instead of the environment they run in.

Potential use cases

Organizations that utilize this service include:

  • Hospitals (healthcare)
  • Universities (education)
  • Government (local, state, and federal)

  • DNS traffic is routed via Traffic Manager, which can easily move traffic from one site to another based on policies defined by your organization.
  • Azure Site Recovery orchestrates the replication of machines and manages the configuration of the failback procedures.
  • Blob storage stores the replica images of all machines that are protected by Site Recovery.
  • Azure Active Directory is the replica of the on-premises Azure Active Directory services allowing cloud applications to be authenticated and authorized by your company.
  • VPN Gateway: The VPN gateway maintains the communication between the on-premises network and the cloud network securely and privately.
  • Virtual Network: The virtual network is where the failover site will be created when a disaster occurs.
