This doesn't seem cheap
>> £0.001 Core per second
That works out at over £2500 for a single core running for a month. And thats without memory costs etc...
That is very likely a display issue and they round up way way too much in that table. In the Pricing Example they use $0.0000125 per Core, which would make it ~33$ for a month for a single core, and double that if you include 1 GB of memory.
