There are some distinctive difference between an on-demand SaaS application and the traditional software. Experts say that in order to be a successful SaaS company, there are three must-haves to consider, as far as the SaaS infrastructure is concerned.
The SaaS should be available thru the web. In an SaaS infrastructure, web developers should consider that most of the next generation of clients are not agreeable with something that they cannot easily buy online. It is actually surprising to note that only 13% of SaaS vendors allow online sign up for their applications. A SaaS infrastructure should be available on the web because this is the most effective way to gather and filter possible customers. Also, this can encourage the vendors to assure customers that the applications are web-ready. Additionally, this can also make the software understandable and accessible.
SaaS infrastructure should be more of solutions than components. Normally, most of the conventional software simply provides nothing but a set of tools that users still have to grasp with even before they can finally produce any utility. The SaaS infrastructure has to be more focused not on the toolsets, but on the problems instead in order to have the most comprehensive and best business results.
SaaS infrastructure: Success-based pricing. The proper SaaS infrastructure expects the clients to pay only the application successfully used. This is contrary with what most traditional hosting models go about: charging for the bandwidth and the disk and processor consumption.
Generally, the SaaS infrastructure is far more efficient and useful because of its practicability. This is one reason why small to medium-scale businesses are suited for this type of web hosting application.
