A new generation of A-series instances is available for Azure Virtual Machines. These Av2 instances carry the same CPU configurations, but we have raised the amount of RAM per vCPU. We have also improved our local disk random IOPS to be two to ten times faster than the existing A-series.
Av2 instances will be available in all locations. For more information, see the Sizes for virtual machines in Azure article. For a comprehensive look at pricing, please visit the Azure Virtual Machines pricing page.
