You can't even log into the instance at all for that price. You also have to pay for bandwidth (very expensive) and EBS (not bad, unless you want it to be as fast as DO's local SSD).
Setting aside that the DO droplets are far more bang for the buck in terms of consistent CPU usage, and also (to be fair) that AWS offers far more scalability options, bandwidth alone is shockingly expensive at AWS.
At 9 cents per GB, you'd be looking at $90/mo for bandwidth alone for what DO gives you included in the $5/mo.
The $80/mo Digital Ocean server w/ 5TB of transfer would cost $450 at EC2 JUST IN BANDWIDTH ALONE!!
And, at DO, if you exceed that bandwidth allocation that's included for free, it's $20/TB vs $90/TB at EC2 (both charge outgoing only).
These are costs that most people don't consider but really amount to poorly explained fine print costs. (Others include Glacier restore pricing, intra-region bandwidth, etc.)
(disclaimer: I'm an AWS certified SA and my SSH key manager startup, Userify[1], is an AWS partner, but even so we are still forced to use DO for a large part of our infrastructure -- especially where bandwidth is concerned.)
