This presentation was prepared as background material for 2009 Channel Focus Europe [22/23 october - see www.baptie.com]. In a session entitled "How to Leverage Business Partners' Migration to SaaS / Cloud", Loic Simon shared IBM's Club Alliances experience on leveraging business partners migrating to a SaaS/Cloud based business model. After a quick summary of SaaS and Cloud challenges for Vendors and their Business Partners, he delivered a point of view on SaaS/Cloud distribution and influence channels and shared his hands-on experience as the leader of "Club Alliances" [www.cluballiances.com]. Club Alliances members leverage cloud computing, SaaS and BPO [business process outsourcing] models to promote and deliver business solutions, "as a service". Their "Solutions as a Service" are typically powered by IBM IaaS [Infrastructure as a Service] or PaaS [Platform as a Service] components. Aknowledgments : Among various materials borrowed from key specialists on the topic [thanks to all of them : Lustratus, Gilwell Group, Saugatuck...], Loic specifically leveraged some slides from presentations prepared by Philippe Martinez - Philmart - and Laurent Glaentzer - Lemon Operations, two members of Club Alliances who deliver their channel expertise to their fellow Club Alliances members.
