It's worth noting that the quoted "$0.50 a month" only applies for the first year, after which it will cost $0.02 an hour or ~$15 a month.
That would make it harder to run, but it would greatly reduce the cost. I'd pay $0.02 for an hour's worth of security while stopping off at a coffee shop.
The API-based management is what makes cloud providers really special.
I mean if you need to login there first via an unsecure session, its not really that much safer
1yr: $54 one-time fee: $0.007 * 24 * 365 = $61.32 + $54 = $115.32 / 12 = $9.61 per month.
3yr: $82 one-time fee: $0.007 * 24 * 365 = $61.32 * 3yr = $183.96 + $82 = $265.96 / 36 = $7.39 per month.
