why SaaS matters...

With failed integration process over & over again enterprises are way too cautious when it comes to going through yet again an integration.Though things have changed & from a rigid, ad hoc based integration now we have a more flexible & cost effective integration solution using web services & SOAP.Along with companies turning to hosted on-demand applications for various reasons (cost effectiveness & no management overheads) & with a built in support for SOAP by SaaS providers has made it much more easier to integrate end to end with onsite/on premises applications. this has given way to solutions providers to incorporate various business models like SaaS(software as a service), PaaS(platform as a service) & now with cloud computing in picture its even a CaaS(computation as a service) option easily available. So i guess eventually all enterprises now can be virtually on line/on internet with minimal IT teams deployed in house.
