Reasonable people can disagree about how fast cloud computing is growing, but everyone agrees that it’s growing.
And Cloudyn —founded four years ago to help customers track their use and get the most out of what they spend on cloud services from Amazon (AMZN), Microsoft(MSFT), and Google(GOOG)—now has $11 million in new Series B funding to expand its services worldwide and beef up sales and marketing.
The company is one of a handful of third parties taking on this task. Competitors include companies like CloudHealth Technologies, Cloud Cruiser and Cloudability. Newvem, another rival, was purchased by Datapipe two years ago.
The latest infusion, which brings total funding to $14.5 million, was led by Carmel Ventures, part of the Viola Group. Previous backers Titanium Investments and RDSeed also participated. Ronin Nir, general partner at Carmel Ventures, now joins the Cloudyn board.
Cloudyn’s business mirrors what’s going on in public cloud computing—which combines massive pools of shared servers, storage, and networking that companies rent to augment (or in some cases replace) internal IT gear.
It started out solely focused on Amazon Web Services, the great-grandaddy of public cloud which started rolling out its services in 2006. Then it added support for Microsoft Azure, Google Cloud Platform—and said it will also support OpenStack-based clouds from Rackspace (RAX)—as well as nearly every other tech vendor, as well.
Sharon Wagner, founder and chief executive of Cloudyn, based in Tel Aviv, said the company has many Fortune 1000 customers, which he could not name citing confidentiality agreements. But he did say that the list includes “the biggest IT consultancy firm and biggest aviation company and biggest salesforce company in the world.”
The big cloud providers offer their own cloud monitoring services, but companies like Cloudyn and Cloudability say customers need neutral third-party tools to find out what cloud services are best for them.
