There appears to be a pretty big gap between the pricing of the WorkSpaces Windows machines and the same(?) machines purchased through EC2. For example, an m3.medium is 1 vCPU, 3.75GiB and is ~$126/mo. The Standard WorkSpaces machine is 1 vCPU, 3.75GiB and $35/mo.
Are there reasons not to move Windows workloads from EC2 to WorkSpaces?
The windows EC2 machines are also designed for web traffic (IIS servers). I suspect these machines will still get traffic but not at the volume of a web server.
They just announced the new pricing [0]. It's much cheaper, but still about 2x the price of the WorkSpaces. The only difference I can see is the local storage: 4 GB SSD on EC2 vs. 50 GB on WorkSpaces. I have to assume WorkSpaces is using a spinning HDD in that case.
