A real SaaS model visualizes both the software vendor and the service provider as the same. Here, a typical scalable metric based transactions, dollar volume or employees determine the charges. Instances, licensed users or machines do not play any role here. The software vendor controls or owns the infrastructure and capital investments. There is a license to the software underlying. However, this license is not at the front-and-center part of the whole relationship.

Here is an explanation on some of the benefits and risks associated with SaaS.

With so many benefits to enjoy, we must not forget the flipsides SaaS comes with. The costs here are not able to come with additional economies for growth or good amount of during reduction due to shrinkage. Customers may have to face undue expenses for upgrades or professional services when a single vendor controls both the software and infrastructure related to it.

Flipsides:

The primary feature of SaaS delivery is standardization. This may prove to be a benefit or liability from the customer’s point of view. SaaS promotes standardization of baseline in conjunction with customizations usually resulting from business rule implementations and not from underlying transformation to the software.

SaaS is also subject to substantial institutional risk. When you sign on with a SaaS vendor, it indicates that the control is handed over to a third party wherein the control is related to production, its’ subject and the data lying within. The customer would not be left with any software if protection is not emphasized upon.

Hence SaaS relationships should include protections such as transition-in plans and transition-out plans. Data protection should also be considered seriously.
