Which virtual machine size should be recommended for general-purpose use workloads in Azure Virtual Desktop?

The D-series virtual machines are specifically designed for general-purpose use workloads in Azure Virtual Desktop. They offer a balanced combination of CPU, memory, and storage capabilities, making them ideal for typical applications and workloads, such as office productivity, light database usage, and general purpose web serving. This versatility is critical in environments where clients may require a range of applications to run concurrently without significant resource contention.

The D-series VMs come with varying sizes to accommodate different workload needs, providing flexibility for scaling as user demand varies. Additionally, the pricing model for D-series is also favorable for standard workloads, making it a cost-effective choice for users looking to deploy Azure Virtual Desktop solutions.

Other virtual machine series have specific use cases that may not align as well with general-purpose workloads. For example, E-series VMs are optimized for heavy memory usage, making them suitable for applications that require a large amount of RAM. FX-series VMs are tailored for high-performance computing scenarios, and N-series VMs are designed for GPU workloads, which are focused on graphic-intensive applications. Therefore, while these series have their strengths, they do not align with the needs of general-purpose use like the D-series does.
