Solution architecture: Enterprise-scale disaster recovery

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, 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.

Products/Description Documentation

Traffic Manager

DNS traffic is routed via Traffic Manager which can easily move traffic from one site to another based on policies defined by your organization.

Site Recovery

Azure Site Recovery orchestrates the replication of machines and manages the configuration of the failback procedures.

Blob storage

Blob storage stores the replica images of all machines that are protected by Site Recovery.

Azure Active Directory

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.
