Microsoft announce that a 5-year Reservation is now available for the Azure HBv2 virtual machine. The existing 1 and 3-year Reservations give an estimated 25% and 50% saving on the compute costs of the VM, and the new 5-year Reservation increases savings to approximately 67%.
The announcement (https://bit.ly/32EWfI9) states that terms and conditions are mostly the same as for all other types of Reserved Instances, and page 54 of the July 2020 Product Terms confirms that the early termination fee for a 5-year Reservation is 35%, rather than the usual 12%.
