For more information, see . You have now successfully created a DNS policy that provides application load balancing across Web servers in three different datacenters. You can create thousands of DNS policies according to your traffic management requirements, and all new policies are applied dynamically - without restarting the DNS server - on incoming queries. To add geo-location awareness to application load balancing, see . Use DNS Policy for Application Load Balancing With Geo-Location Awareness You can use this topic to learn how to configure DNS policy to load balance an application with awareness. The previous topic in this guide, , uses an example of a fictional company - Contoso Gift Services - which provides online gifting services, and which has a Web site named contosogiftservices.com. Contoso Gift Services load balances their online Web application between servers in North American datacenters located in Seattle, WA, Chicago, IL, and Dallas, TX. Note It is recommended that you familiarize yourself with the topic before performing the instructions in this scenario. This topic uses the same fictional company and network infrastructure as a basis for a new example deployment that includes geo-location awareness. In this example, Contoso Gift Services is successfully expanding their presence across the globe. Similar to North America, the company now has web servers hosted in European datacenters. Contoso Gift Services DNS Administrators want to configure application load balancing for European datacenters in a similar manner to the DNS policy implementation in the United States, with application traffic distributed among Web servers that are located in Dublin, Ireland, Amsterdam, Holland, and elsewhere. DNS Administrators also want all queries from locations in the world distributed equally between all of their datacenters. In the next sections you can learn how to achieve similar goals to those of the Contoso DNS Administrators on your own network. How to Configure Application Load Balancing with Geo-Location Awareness The following sections show you how to configure DNS policy for application load balancing with geo-location awareness. Important The following sections include example Windows PowerShell commands that contain example values for many parameters. Ensure that you replace example values in commands with values that are appropriate for your deployment before you run these commands. Create the DNS Client Subnets You must first identify the subnets or IP address space of the North America and Europe regions.
