Issue: Frequent AVD Disconnections on High-Latency Network

Question

Observed Problem:

Our AVD host pool is deployed in two regions within the US. However, 50% of our user base is in India, experiencing frequent disconnections due to latency exceeding 140 ms.

Guidance Needed:

What are the possible strategies to reduce latency without relocating the AVD host pool to India?

Has anyone successfully configured an AVD host pool in India while implementing strict data security measures? If so, what options were considered?

Hi Prathap KrishnaPandian,

There are Strategies to Reduce Latency Without Relocating the AVD Host Pool to India:

To Optimize Network Routing:
Use Azure ExpressRoute to establish a private, high-speed connection between your on-premises network and Azure. This can reduce latency by avoiding the public internet.
Implement Azure Traffic Manager to route users to the nearest Azure region based on their geographic location. This can help balance the load and reduce latency.
Azure Front Door can optimize the routing of traffic to the nearest Azure region, reducing latency by leveraging Microsoft's global network.
Use Azure Content Delivery Networks CDN to cache static content closer to your users in India, reducing the load on the AVD host pool and improving performance.
Ensure that users are using the latest AVD client software, which includes performance improvements and optimizations.
Optimize the session hosts by using performance tuning techniques, such as enabling GPU acceleration, optimizing the OS, and using SSD-based storage.

A case study by NSN Infotech details how an engineering company with a globally distributed remote workforce deployed AVD within Microsoft's India-based Azure regions. This setup provided private and secure access to the AVD environment for employee devices, ensuring high-performance computing with robust data protection, thereby minimizing risks associated with remote work environments: Enhancing Data Security and Performance for Remote Engineering Teams with Azure Virtual Desktops
