Introduction

Over the last couple of years, there has been an impressive flux with many businesses and institutions adopting and relying on large-scale remote working and remote learning environments to maintain workforce and learning continuity. During this time, it’s generally been recognised that this type of remote working/learning has been quite successful, with many businesses and institutions continuing remoting working/learning practices or introducing hybrid models with a combination of remote and office work for their staff. 

One of the reasons why remote working/learning has been successful is the availability of supporting technologies that have delivered a high standard of human communication and engagement across large numbers of workers or students/faculty in remote environments. Video conferencing applications, which includes video conferencing, screen sharing, IMs and more, are such technologies that have contributed to viable remote working/learning environment success.  

But to use these applications to their fullest potential, a robust IT infrastructure is also a must. Many large enterprise companies, as well as SMB and other institutions have centralised their IT environment into virtualized desktop infrastructure (VDI), either as an on-premises solution or as a managed-service by cloud service providers (CSP). Centralizing resources, applications and data into a single infrastructure allows for better IT management and security of vital resources and data which can help improve workforce productivity, data security and IT efficiencies.

Investigation overview

This blog details a recent technical investigation where popular video conferencing applications are deployed on AMD-based Azure instances to determine the performance of each application, the number of deployable users in a multi-session environment, and the user experience each person would receive. The AMD-based instances includes both CPU-only based instances and CPU+GPU based instances to understand the impact of GPU-enabled resources to the density and experience of the users.

So next let’s look at the various parameters for the investigation.

For the investigation, we had three areas of consideration: 

1) Azure session host	2) Application	3) End-point devices
