This document discusses IBM's LotusLive cloud-based collaboration platform. It begins by explaining why software as a service (SaaS) is an important delivery model, allowing businesses to access applications via subscription over the internet without owning the software. The document then outlines IBM's LotusLive strategy, which provides cloud-delivered collaboration solutions including messaging, content management, unified communications, and social/situational applications both online through a SaaS model and on-premise if desired. Customers can choose between dedicated hosting or a multi-tenant public cloud environment to suit their needs.
