The price includes $15k/year colocation costs. That easily covers the redundant power, cooling, rack space, massive amount of bandwidth and redundant network network connections. Last place I handled colocated servers, we spent ~$17k combined for racks in two different data centres hosting a combined ~60 servers, so $15k/year for a single server is a very conservative estimate.
If you're buying more than one, that'll easily cover enough to cable up whatever network you want between them.
Many colo providers also have their own cloud services, and nothing stops you from using S3, SQS and the like, though of course if you use AWS services "from the outside" you do need to factor in their extortionate outbound bandwidth charges.
