Comparison of cloud server products

Compile min 20 page (1800 characters/page in English) comparison of cloud server products. At minimum, it should include Openstack, Cloudstack and OnApp platforms and min 2 more. At authors discretion additional ones can be included to fill in the space more easily. It should have general description of each product and comparison table. It is for internal use (will not be published), so copy/paste from other sources is allowed. I will not be knitpicking. Need something quick and dirty. Will be translated to other language. Invoice required.
