Do you an email client such as Outlook or Mail.app, or do you use
Gmail, Yahoo Mail, or some other web-based system for your email? The former
are examples of the traditional software model, while the latter are examples
of SaaS.
The chief advantage of SaaS is that there is no installation or
maintenance required by the client: everything is handled by the provider. The
downside is that you don't control when the software is upgraded or changed.
Security is often mentioned as a reason not to use SaaS, but unless
your company is not connected to the internet, your data is most likely safer
with a SaaS provider than on your own servers. Think about it: these providers'
business models require trust; if they were to suffer a security breach they
would most likely go out of business. They invest heavily in security to
minimize the chances of that happening. Does your company have security experts
on-site monitoring for suspicious activity? No, I didn't think so.
One other big thing is who "owns" the data. Obviously it is the
client's data, but if the provider doesn't offer a way to get a full copy of
that data, you are then locked into using that provider.
