I'm seems pretty reasonable for a cloud PC.

I just ran the costs through the Azure calculator, and a D2asV6 system with a 100GB drive and licenseing running 16hrs a day, 30 days a month would cost approximately 1200 dollars annually, so 99 bucks a year seems like a steal.

And a D2asV6 is not a lot of compute power. 2 cores, 8Gb ram.

In summary, Azure is fucking expensive if you are keeping VMs online all the time.
