Task 1: Create two instances of a web app<\/strong><\/p>\n\n\n\n
This lab requires two instances of a web application that run in different Azure regions. Both the web application instances run in Active\/Active mode, so either one can take traffic. This configuration differs from an Active\/Stand-By configuration, where one acts as a failover.<\/p>\n\n\n\n

<\/figure>\n\n\n\nTask 2: Create a Front Door for your application<\/strong><\/p>\n\n\n\n
Configure Azure Front Door to direct user traffic based on lowest latency between the two web apps servers. To begin, add a frontend host for Azure Front Door.<\/p>\n\n\n\n
- On any Azure Portal page, in Search resources, services and docs (G+\/)<\/strong>, enter front door, and then select Front Doors<\/strong> from the results.<\/li><\/ul>\n\n\n\n
![\"\"](\"https:\/\/exceedthecloud.com\/wp-content\/uploads\/2022\/02\/img7-13-1024x519.png\")

<\/figure>\n\n\n\n- Select Next: Configuration<\/strong>.<\/li>
- On the Configuration tab, in Frontends\/domains<\/strong>, select +<\/strong> to add a frontend host.<\/li><\/ul>\n\n\n\n
![\"\"](\"https:\/\/exceedthecloud.com\/wp-content\/uploads\/2022\/02\/img9-13-1024x409.png\")
<\/figure>\n\n\n\nEnter a globally unique host name<\/strong>, like Exceedlabs-frontend12022022, and then select Add<\/strong>.<\/p>\n\n\n\n
![\"\"](\"https:\/\/exceedthecloud.com\/wp-content\/uploads\/2022\/02\/img10-13.png\")
<\/figure>\n\n\n\n- Next, create a backend pool that contains your two web apps.
\u200eIn Create a Front Door, in Backend<\/strong> pools, select + to add a backend pool.<\/li><\/ul>\n\n\n\n![\"\"](\"https:\/\/exceedthecloud.com\/wp-content\/uploads\/2022\/02\/img11-12-1024x412.png\")
<\/figure>\n\n\n\n- Enter a host name, like BackendPool<\/strong>.<\/li>
- Under BACKENDS<\/strong>, select + Add a backend<\/strong>.<\/li>
- In Add a backend, enter, or select the following information.<\/li><\/ul>\n\n\n\n
Setting<\/strong><\/td> Value<\/strong><\/td><\/tr><\/thead> Backend host type<\/td> Select App service<\/strong>.<\/td><\/tr> Subscription<\/td> Select your subscription.<\/td><\/tr> Backend host name<\/td> Select the first web app you created.

![\"\"](\"https:\/\/exceedthecloud.com\/wp-content\/uploads\/2022\/02\/img13-12.png\")
<\/figure>\n\n\n\n- Select + Add a backend<\/strong> again, enter or select the following.<\/li><\/ul>\n\n\n\n

![\"\"](\"https:\/\/exceedthecloud.com\/wp-content\/uploads\/2022\/02\/img14-13.png\")
<\/figure>\n\n\n\nOn the Add a backend<\/strong> pool<\/strong> blade, select Add<\/strong> to complete the configuration of the backend pool.<\/p>\n\n\n\n
![\"\"](\"https:\/\/exceedthecloud.com\/wp-content\/uploads\/2022\/02\/img15-12.png\")
<\/figure>\n\n\n\n- Finally, add a routing rule. A routing rule maps your frontend host to the backend pool. This rule forwards a request for Exceedlabs-frontend20022022.azurefd.net to myBackendPool.<\/li><\/ul>\n\n\n\n
- In Create a Front Door, in Routing rules<\/strong>, select +<\/strong> to configure a routing rule.<\/li><\/ul>\n\n\n\n
![\"\"](\"https:\/\/exceedthecloud.com\/wp-content\/uploads\/2022\/02\/img16-12-1024x408.png\")
<\/figure>\n\n\n\nIn Add a rule, for Name<\/strong>, enter LocationRule.<\/p>\n\n\n\n
![\"\"](\"https:\/\/exceedthecloud.com\/wp-content\/uploads\/2022\/02\/img17-12.png\")
<\/figure>\n\n\n\nAccept all the default values, then select Add<\/strong> to add the routing rule.<\/p>\n\n\n\n
![\"\"](\"https:\/\/exceedthecloud.com\/wp-content\/uploads\/2022\/02\/img18-11-1024x411.png\")
<\/figure>\n\n\n\nSelect Review + Create<\/strong>, and then Create<\/strong>.<\/p>\n\n\n\n
![\"\"](\"https:\/\/exceedthecloud.com\/wp-content\/uploads\/2022\/02\/img19-10.png\")
<\/figure>\n\n\n\nYou must ensure that each of the frontend hosts in your Front Door has a routing rule with a default path (*) associated with it. That is, across all your routing rules there must be at least one routing rule for each of your frontend hosts defined at the default path (*). Failing to do so may result in your end-user traffic not getting routed correctly<\/strong>.<\/p>\n\n\n\n
Task 3: View Azure Front Door in action<\/strong><\/p>\n\n\n\n
Once you create a Front Door, it takes a few minutes for the configuration to be deployed globally. Once complete, access the frontend host you created.<\/p>\n\n\n\n
- In the Azure Portal, navigate to your Front Door frontend. Select Go to Resource<\/strong>. Or in Search resources, services, and docs (G+\/), enter front door<\/strong>, and select Front Doors<\/strong> from the results, and then select your Front Door.<\/li>
- On the Front Door page, note the Frontend host<\/strong> URL. This lab uses Exceedlabs-frontend12022022.azurefd.net, but you may have altered it to ensure the name is unique.<\/li><\/ul>\n\n\n\n
![\"\"](\"https:\/\/exceedthecloud.com\/wp-content\/uploads\/2022\/02\/img20-10.png\")
<\/figure>\n\n\n\n- In a browser, go to your Frontend host URL (Exceedlabs-frontend12022022.azurefd.net). Your request will automatically be routed to the nearest server to you from the specified servers in the backend pool.<\/li>
- You\u2019ll see the following information page:<\/li><\/ul>\n\n\n\n

- Switch to the Azure portal, search for and select App services<\/strong>.<\/li>
- Select one of your web apps, then select Stop<\/strong>, and then select Yes<\/strong> to verify.<\/li><\/ul>\n\n\n\n

![\"\"](\"https:\/\/exceedthecloud.com\/wp-content\/uploads\/2022\/02\/img23-8-1024x243.png\")
<\/figure>\n\n\n\nThere may be a delay while the web app stops. If you get an error page in your browser, refresh the page<\/strong>.<\/p>\n\n\n\n
- Switch back to the Azure Portal, locate the other web app, and stop it.<\/li>
- Switch back to your browser and select Refresh. This time, you should see an error message.<\/li><\/ul>\n\n\n\n
