6. Is SaaS only meant for SMEs?

7. Can enterprises benefit from SaaS?
Yes. Enterprises can also make use of available SaaS to lower their expenditure on hardware and instead use SaaS for their operations.
8. What is the difference between SaaS and ASP?
ASPs hosted applications from other companies and then licensed it to end users. ASPs generally had limited customization potential as they deployed applications that are developed by someone else.
The ASPs did not change the architecture of their applications; they merely provided legacy applications to user organizations. The up-front and ongoing costs of hosting legacy applications were quite hefty. During the ASP days, a very small segment of the market was willing to outsource their application needs to relatively untested outfits because most companies during the dot-com era felt that their IT operations and business applications were a strategic asset. Corporations today consider operating IT functions and business applications as commodities and not central to the organisation’s competencies.
SaaS is built from the ground up to service many customers from the start, very much unlike the ASPs.
9. How is SaaS related to Grid Computing?
SaaS applications need a hosting platform to which they can be hosted. Grid computing can provide the underlying architecture so that compute resources can be provisioned easily and flexibly for the hosted applications. This way the user does not have to invest large amounts of money in infrastructure, which may often be underutilized.
10. How is SaaS related to Cloud Computing?
SaaS are often hosted on a Cloud via a web interface.
