Answer 1

Hello @Sean Jerzewski,

The Standard_B1s VM size belongs to the B-series (burstable) virtual machines.

If you are seeing “Size not available” even after changing regions or security settings, this is typically due to SKU retirement, regional capacity, or subscription-level limitations, rather than any configuration issue.

The original B-series (v1) virtual machines are scheduled for retirement by November 2028. Due to this retirement plan, many regions have already restricted or removed availability of these VM sizes, especially for new deployments.

Official retirement announcement:-

• Retirement: The F, Fs, Fsv2, Lsv2, G, Gs, Av2, Amv2, and B series VMs are retiring in 2028
• Retired Azure VM size series

What can be done to create a free VM?

You can opt for B2ATs or B2PTs VM sizes for Linux based VM to create or if you are trying to create a Windows based VM you can choose B2ATs sized VM and make sure to use 64GiB for OS disk and without a public IP.
