"Stuff doesn't just work or operate on its own," Wiley said. "Even if it's in Office 365 or Azure, it needs time and attention."

Aldridge has relied on attrition to realign its workforce, Wiley said, and hasn't experienced any real turnover specifically related to the fortunes of its IaaS or SaaS businesses.

"No one has specifically lost their job as a result of this," he said.

The biggest reason some customers are remaining with Aldridge's hosted cloud rather than switching to one of the public cloud providers is its ability to to work around complex infrastructures, Wiley said. Aldridge offers more customization around complicated VPN setups or other elements of complex environments, he said.

Complexity alone is a "major driver," he said.

But while those customization features aren't offered by major cloud providers, Wiley said he knows they will eventually come.

As a result, Aldridge is investing in its own virtual infrastructure at a much lower rate since the company doesn't want to put $1 million into its IaaS offering and see it shut down in a few years, Wiley said.

Aldridge plans to continue gazing into the crystal ball in hopes of ensuring that its investment priorities match up with future levels of demand.

"Don't assume that, just because something has been a big part of your business with a big margin, that it will stay that way," Wiley said. "Be very open-minded as to what the competition is doing."
