How many of those "cloud-based" solutions are written in PHP, Java, or Python and hosted on LAMP servers? You know, the ones with "Enterprise" features and "24x7 availability", and stiffly worded SLAs?
Lots and lots.
Working at such a hosted solution provider, we replace 50 to 100 onsite servers with 1 or 2 of our own and profit immensely on economies of scale. While we diligently scan uploaded data for viruses, we also benefit from having robust security, firewalls, and rapidly updated servers. In nearly 10 years of doing business like this, we've had zero virus outbreaks and uptime approaching 4 nines. We don't get complaints about our reliability, a few hours of downtime per year.
