We are excited to announce the Public Preview of Generation 2 virtual machines on Azure. Generation 2 virtual machines use the new UEFI-based boot architecture vs. the BIOS-based architecture used by Generation 1 virtual machines. The new architecture enables customers to:
Build large virtual machines (up to 12TB)
Provision OS disks sizes that exceed 2TB, and
Leverage advanced security capabilities like SecureBoot and Virtual Trusted Platform Module (vTPM) to secure their Virtual Machines.
