How to Deploy and Configure Azure Application Gateway

To Deploy and Configure Azure Application Gateway

Introduction:

Azure Application Gateway is a web traffic load balancer that allows you to handle traffic to your web applications. Traditional load balancers perform at the transport layer (OSI layer 4 - TCP and UDP) and route traffic based on source IP address and port, to a destination IP address and port.

Procedure:

Step 1: Log in to Azure Portal

Step 2: Visit the Azure portal and search for “Application gateways” and then click “Add”.

Step 3: After this, fill all the basic details such as the resource group, autoscaling details, and virtual network. Also create a new VNet, if it does not exist before, and then click on “Frontends”.

Step 4: After you have clicked on “Frontend” in the previous step, choose “Frontend IP address type”, create a new Public IP address, and then click on “Backends”.

Step 5: Now, select the required backend pool for the application gateway and then click on “Configuration”

Step 6: Add a routing rule; enter the “Rule name” and then specify the routing rules here along with the backend targets.

Step 7: Each backend target, create a specific HTTP setting; click on “Create new” under “HTTP setting”, and specify the backend protocol and port.

Step 8: To add a routing rule, specify the target type, path, and HTTP setting for that backend target. After that, click on “Save changes” and go back to routing rules.

Step 9: The default route and multiple path-based rule targets will appear under Backend targets; here, click on “Add” after filling in the details.

Step 10: You will be able to view Frontends, Routing rules, and Backend pools for the application gateway; click on “Review + create” to deploy the application gateway.

Step 11: Next go to create two virtual machines and Select virtual machine1 and click Create

Step 12: Enter the Project details Instance Details and Administration account details

Step 13: Enter the Disk Details and click next

Step 14: Enter the Networking Interface Details

Step 15: Set to Default configuration in management, advanced and tags tab

Step 16: Review and Click Create to create the virtual machine

Step 17: Next Again create a second virtual machines for same steps.

Step 18: Next go to resource Copy the public ip address and login via ssh virtual machine 1

Step 19:Next go to resource Copy the public ip address and login via ssh virtual machine 2

Step 20: update the two virtual machine repository and install Nginx server at bot machines.

Step 21: go to the browser and browse the public virtual machine ip address.

Step 22: Now I am difference from two nginx server so go to nginx configuration file and edit the content for both virtual machines.

Step 23: Again go to browser refresh the page.

Step 24: Next go to the application gateway and click backend pool select the virtual machines and targets then save.

Step 25: click overview for application gateway copy the frontend public URL and go to browser browse the ip address.

Step 26: you will see the application gateway using for load balancer function.
