Task 3
You need to ensure that an Azure Web App named az400-38443478-matn supports rolling upgrades The solution must ensure that only 10 percent of users who connect to az400-38443478 main use updated versions of the app. The solution must minimize administrative effort.
Create a Deployment Slot:
Navigate to the Azure Portal.
Go to your Web Appaz400-38443478-main.
SelectDeployment slotsin the menu.
Click on Add Slot.
Name the slot (e.g.,staging) and if needed, clone settings from the production slot.
Configure the Traffic Percentage:
In the Deployment Slots menu, you will see a column for Traffic %.
Set the traffic percentage to10%for thestagingslot1.
This will route only 10% of the traffic to the updated version of the app in thestagingslot.
Deploy the Updated App to the Staging Slot:
Deploy yourupdated application to thestagingslot.
Test the application in thestagingslot to ensure it’s working as expected.
Complete the Rolling Upgrade:
Once you’re satisfied with the performance and stability of the app in thestagingslot, you can gradually increase the percentage of traffic until you’re ready to swap with the production slot.
To swap slots, go to the Deployment slotsmenu and click on Swapwith the production slot.
By using deployment slots, you can achieve rolling upgrades with minimal administrative effort, as it allows you to test the new version on a subset of users before fully releasing it. Remember to adjust the traffic percentage and monitor the application’s performance throughout the process.
