Network woes? The cloud is coming to the rescue

Cloud computing is changing the game for one of the hardest problems in IT: running a network.

Users are counting on fast, secure access more than ever, even as networks get more complex and threats more dangerous. Often, there’s a lot of data available about the state of a network and its performance, but more data by itself can’t solve a problem. So startups are turning to the growing power of the cloud for answers.

Nyansa, based in Silicon Valley, emerged from stealth mode on Monday with Voyance, a cloud-based SaaS (software-as-a-service) offering that analyzes inputs from wired and wireless LANs to gauge users’ actual experiences on a network.

The company’s launch follows one earlier this month by Veriflow, a cloud-based startup that analyzes all possible data flows to determine whether security policies are working. It’s a broader trend, too, with companies like Dell taking their systems management software into the cloud.
