Is Amazon Workspaces free ?
The Amazon WorkSpaces Free Tier provides two Standard bundle WorkSpaces, running in AutoStop mode, for up to 40 hours of combined use per month, for two calendar months, from the time you create your first WorkSpace. Usage time accrues while you’re actively using your WorkSpace as well as the time it takes to stop after a specified period of inactivity, which by default is set to one hour. If you exceed the Free Tier limits, you will be charged the standard Amazon WorkSpaces hourly rate for the additional resources you use. At the end of two calendar months, the WorkSpaces you launched in the Free Tier will automatically be billed at the applicable hourly rate.
