Reasons for SaaS:
So you’ve decided your software product needs to be a SaaS application development Java. You’ve no doubt picked SaaS because your customers would like a cloud based application that they can access from the web anywhere they need it. This also implies your customer base has no interest in maintaining an IT staff to maintain software and equipment in-house. They are also interested in the low cost of ownership, on demand scalability, tailored Service Level Agreements, and the fact that “someone else” is worrying about upgrades, feature development, security, and all the other responsibilities that come from in-house development.
