Comments on: What is a Cloud? http://blog.softlayer.com/2010/what-is-a-cloud/ A Behind the Scenes Look at the Best Hosting Provider in the World Tue, 21 May 2013 00:08:33 +0000 hourly 1 http://wordpress.org/?v=3.4.1 By: Jeff Huckaby http://blog.softlayer.com/2010/what-is-a-cloud/comment-page-1/#comment-4986 Jeff Huckaby Thu, 30 Sep 2010 14:28:27 +0000 http://blog.softlayer.com/?p=1737#comment-4986 One of the best descriptions or definitions of cloud I have seen was offered by Lydia Leong during Hostingcon 2010. The 5 items she highlights: 1. Service Based - consumer concerns are abstracted from provider concerns, think SOA 2. Scalable and elastic 3. Shared - services share a pool of resources 4. Metered by Use 5. Internet Technologies - delivered through internet protocols, formats, identifiers I would then use Public vs. Private to differentiate between pools of resources are shared amongst different companies vs. pools of resources dedicated to a specific company. You can also have multi-tenant private clouds where the tenants may be different organization units or applications within your business.
