Connectivity for App to reduce NW delay

Pankaj Bhalgat 20

My application is deployed in Azure India, and US users experience delays when they try to connect to it. How can I use the Azure backbone network to improve the performance of my application for US users?

Hello @Pankaj Bhalgat ,

Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

I understand that you have an Application hosted in India region and the users from US region are experiencing some delays during the connection.

Could you please kindly provide more details regarding your current scenario, current configuration and how the users in India and US access the Application?

Looking forward to hearing from you so I can provide a few suggestions.

Thank you very much for the additional information.

Regards,

This timesheet application is deployed on two virtual machines (VMs), one for the application and one for the database. The application VM has a public IP address and a public DNS name, so users can access it from the internet. The application works fine for users in India, but US users experience delays.

Can I use the Azure backbone network for US users?

Hello @Pankaj Bhalgat ,

Thank you for your response.

So, you have one VM for Application with a Public Name and Public IP and another VM for Database.

Regarding the Public Name on the VM Application, is it a Public Domain or it belongs specific to that VM (DNS label)?

Since you have resources in different regions, you will need to balance the traffic for your application accordingly.

To be able to do that, we have a few products which could be helpful in this situation: Azure Front Door and Azure Traffic Manager.

Traffic Manager is a DNS-based load balancer that offers different algorithms for routing to the right region. It uses DNS resolution to redirect requests to an appropriate geographical location endpoint, which means that when a user makes a request to your application FQDN, it will check from where this request is coming from and then forward to the most appropriated endpoint.

Front Door is a global HTTP load balancer that offers features like Web Application Firewall and SSL Offloading. Azure Front Door delivers your content using Microsoft’s global edge network with hundreds of global and local points of presence (PoPs) distributed around the world close to both your enterprise and consumer end users. It offers a single global entry point for customers accessing web apps, APIs, content and cloud services.

Can you please tell me where to place the Front Door or Traffic Manager in the existing Azure backbone network architecture to reduce delay?

Hello @Pankaj Bhalgat ,

Thank you for your response.

The Traffic Manager and Azure Front Door are global resources, they will be added as the frontend of your current Public IP/Application (backend), therefore they will be able to balance the traffic between the regions you have added on your backend.

These load-balancing services distribute traffic across regional back-ends, clouds, or hybrid on-premises services. These services route end-user traffic to the closest available back-end. They also react to changes in service reliability or performance to maximize availability and performance. You can think of them as systems that load balance between application stamps, endpoints, or scale-units hosted across different regions/geographies.

Azure Front Door is an application delivery network that provides global load balancing and site acceleration service for web applications. It offers Layer 7 capabilities for your application like SSL offload, path-based routing, fast failover, and caching to improve performance and high availability of your applications.

Traffic Manager is a DNS-based traffic load balancer that enables you to distribute traffic optimally to services across global Azure regions, while providing high availability and responsiveness.
