When you host your application in a public cloud like Amazon AWS or Rackspace or subscribe to SaaS application like Salesforce or Zoho, your virtual instance shares all the underlying resources like operating system, web server and database with other customers in the cloud.
When you subscribe to our Cloud version of openSIS, you get your own virtual server with its own resources. Very secure, infinitely scalable.

More Flexible than SaaS
A Software as a Service (SaaS) deployment typically means sharing a hosted instance and database with other customers. With openSIS on the Cloud, you get your own private and secure instance of openSIS Lite or openSIS Pro Edition. So you have complete flexibility to customize the solutions as well as control over changes and upgrades. And you can do that quickly and easily with openSIS's easy no programming user interface tool.
