Облачковое - амазон дает микроинстансы от 0.02$ / час

Micro instances provide 613 MB of memory and support 32-bit and 64-bit platforms on both Linux and Windows. Micro instance pricing for On-Demand instances starts at $0.02 per hour for Linux and $0.03 per hour for Windows.

Customers have asked us for a lower priced instance type that could satisfy the needs of their less demanding applications. Micro instances are optimized for applications that require lower throughput, but which still may consume significant compute cycles periodically. Micro instances provide a small amount of consistent CPU resources, and also allow you to burst CPU capacity when additional cycles are available.
