These days there are so many "cloud-based" business applications. When an application is refered to as "cloud-based" that means it will be hosted on someone else's computer. There are many advantages to this especially in the SMB world because traditional IT (or on premise IT) is difficult to maintain and many companies lack the resources to set up new software applications for all their users. However, once a company starts using "cloud-based" applications they give up their privacy rights.
Many times companies, often unknowingly, will entrust their data to a third party through cloud-based services. Many times these cloud-based services become major targets for attackers (since if they are breached it's worth thousands of data-breaches to the attackers) or sometimes worse they monitize your data. Sometimes this is a fair exchange and some data is not private but it seems that, these days, many companies are stuck using "cloud-based" services as there are few alternatives and many of these companies lack the resources to implement solutions on premise.
Often times open source tools are hostable on premise however, as many business owners I have talked to have said, open source can be a blackhole of time; implementation takes time and every configuration seems to be different (that is until they switched to a NetThunder system which self configures these applications). Even with these costs hosting your own applications on open source software (even paid-open source) gives you an outstanding level of freedom and control. You control where your data sits on computers you can physically see and you are never locked in.
At NetThunder we designed our application marketplace for OneClickEnterprise to have a suite of applications to rid ourselves and our customers from all dependencies on the cloud or cloud based services. I have jokingly called us "off the grid but still part of and connected to the modern world." (We aren't really off the grid but our data and our customers' data is off the grid/cloud).
It is fun telling our customers that when they use our platform on premise we physically have no access to their data and we don't mind. We don't want their data and we don't need them to phone home.
