    7. Amazon EC2 Elastic Cloud Computing virtual servers for rent calledAmazon Machine Images (AMIs) based on Xen priced on per hour from $0.10 to $1 Amazon S3 Simple Storage Service up to $0.18 per GB storage from $0.10 per GB transfer via REST SOAP BitTorrent Platforms in the Cloud / SaaS - Amazon Web Services Kelv This all used to be cheap until the started falling against the $Kelv This all used to be cheap until the started falling against the $

    8.
