Every day more companies see the benefits of using cloud services. A number of software vendors have already decided to no longer provide the software for local installation, but are only offering cloud services.

- Can single sign-on be achieved ?

- Is exchange of data required?

- How can data be exchanged in a secure manner with the SaaS provider?

- What is the impact if the SaaS provider runs "out of business " is .

- Is it legally allowed to place data in a public cloud ?

- Who can watch your data when stored in a public cloud ?
