Increasing customer demand for software-as-a-service (SaaS) applications has already convinced 50% of software vendors to deploy some of their business applications via SaaS.

Forrester's PaaS reference architecture is a tool that helps independent software vendors (ISVs), hosting providers, and middleware vendors judge which offerings will bring them some value — and even what they might contribute on their own to this new market. Middleware vendors that are considering bringing a PaaS technology stack to market can validate the completeness of their offering, which they will need to do to become a recognized player in this emerging market.
