Azure IaaS and Azure Stack: announcements and updates (December 2022 – Weeks: 47 and 48)

This series of blog posts includes the most important announcements and major updates regarding Azure infrastructure as a service (IaaS) and Azure Stack, officialized by Microsoft in the last two weeks.



Azure HX series and HBv4 series virtual machines (preview)

The Azure HX series and HBv4 series virtual machines (VMs) are now in preview in the East US region. These VMs, powered by AMD 4th gen EPYCTM “Genoa” CPUs, improve the performance and cost-effectiveness of a variety of memory performance bound, compute bound, and massively parallel workloads. These new VMs deliver more performance, value-adding innovation, and cost-effectiveness to every Azure HPC customer.


Azure Bastion now support shareable links (preview)

With the new Azure Bastion shareable links feature in public preview and included in Standard SKU, you can now connect to a target resource (virtual machine or virtual machine scale set) using Azure Bastion without accessing the Azure portal.

This feature will solve two key pain points:

  • Administrators will no longer have to provide full access to their Azure accounts to one-time VM users, helping to maintain their privacy and security.
  • Users without Azure subscriptions can seamlessly connect to VMs without exposing RDP/SSH ports to the public internet.
