To implement this scenario, we must start by creating 4 Virtual Machines. The application moves the document to Microsoft Azure Storage.The FTP Client connects directly with the healthy Endpoint.

Using the CName FTP Client contacts Microsoft Azure Traffic Manager and is provided with the IP of a healthy Endpoint.So be sure that you take this into consideration when you estimate operational costs for this kind of scenario. Sending a document from one Data Center to an other is considered Egress Bandwidth from the origin. Note: Ingress Bandwidth is free on Azure.

When a document is uploaded over FTP, it is moved to a Microsoft Azure Storage Account that is used as persistent storage. In this specific scenario, we assume that all FTP Servers are configured the same way and that users only have write access. On Azure, we can take advantage of the Microsoft Azure Traffic Manager to direct users to the closest FTP Server. Making an FTP Ingestion Service Highly Available (HA) can be a challenge.
