Azure Virtual Machine Multi Session

Question

Dear teams,

I'm using Azure Virtual Machine on Windows Server 2022. Currently, the machine only supports a maximum of two users accessing it at the same time.

1. Now I want to increase the number of users who can access it. What do I need to do?
2. what licenses are required to allow more users to do it? And if so, is that license already supported by Azure, or do I need to purchase it separately?

Answer 1

By default, Windows Server 2022 allows two concurrent remote desktop sessions under the "Remote Desktop Services" (RDS) licensing model. If you want to increase the number of users who can access the server concurrently, you will need to configure Remote Desktop Services (RDS) and acquire the necessary licenses.

To allow more users to access your Azure Virtual Machine simultaneously, you would need to set up and configure Remote Desktop Services, which involves enabling Remote Desktop Session Host (RDSH) and acquiring the proper RDS Client Access Licenses (CALs). The RDS CALs are available in two types: User CALs and Device CALs. A User CAL allows a specific user to connect from any device, while a Device CAL allows a specific device to connect regardless of the user.

Azure itself does not automatically provide RDS CALs, meaning you will need to purchase them separately through Microsoft or an authorized reseller. These licenses are not bundled with the Azure subscription by default. You can buy RDS CALs either directly through Microsoft's licensing programs or via Azure's Hybrid Benefit, which might offer additional savings if you're using existing Windows Server licenses. Additionally, if you're running multiple servers or need a more flexible and scalable setup, you may want to consider RDS External Connector licenses, which provide access for users who are not part of your organization (such as external users).

Alternatively, you can use Azure Virtual Desktop (AVD) to scale the number of users accessing a virtual machine without the need for traditional Remote Desktop Services (RDS) configuration. AVD is designed for a cloud-native environment, and it enables you to host Windows desktops and applications in Azure, allowing multiple users to access them concurrently. This solution is particularly suited for scenarios where you need to provide access to a large number of users in a scalable and flexible manner.

AVD works differently from traditional RDS. Instead of relying on a single server or a small number of machines with RDS CALs, you create a pool of virtual machines in Azure, where each VM acts as a host for multiple users. This enables the scaling of user access more efficiently, as users can connect to these virtual desktops rather than accessing a single server. The infrastructure is fully managed by Azure, and you can easily scale up or down depending on your needs. This approach also improves resource utilization, as multiple users can share the same virtual machine without affecting performance.

In terms of licensing, AVD requires users to have the appropriate Windows 10 or Windows 11 Enterprise licenses. If your organization already has Microsoft 365 or Windows 10/11 Enterprise E3 or E5 licenses, these should cover the AVD access rights for users. Azure handles the virtual machine infrastructure, but the user licensing is still necessary. This means you don't need to worry about RDS CALs or setting up complex configurations for each user, as long as your users have the proper Microsoft licenses.

One of the key advantages of using AVD is that it is fully integrated with the Azure ecosystem, making it easier to manage virtual desktop environments at scale. With AVD, you get access to features like simplified multi-session configurations, centralized management, security integration with Azure Active Directory, and better scalability to accommodate fluctuating user demand. Plus, since AVD is built for the cloud, it allows you to support a distributed workforce by providing access to virtual desktops from any location, on any device.

Hi

Said in the above comment , by defult all server operating system have only 2 RDP option , if you need extra you need to but additional RDP CAL from Microsoft.
