Scalr, which made its name monitoring the performance of multiple clouds for business customers, just raised $7.35 million in new funding from OpenView Venture Partners.

While Amazon amzn is the big daddy in public clouds—which pool tons of computer, networking, and storage to rent out to customers—many companies don’t want to put all their jobs in one cloud basket.

So if Acme is going to run some workloads on Amazon Web Services, others on Microsoft msft Azure or Google goog Cloud Platform and still others on internally-owned and controlled private clouds—having one tool to monitor all those venues could come in helpful.

Other companies offering multi-cloud monitoring include RightScale and Enstratius, which Dell acquired two years ago.

To date San Francisco-based Scalr has funded operations out of sales, but will use this Series A cash infusion to expand its product line and its sales team.

Scalr chief executive Sebastian Stadil said the time is ripe to invest more in multi-cloud monitoring since cloud is now on the radar for high level executives at Fortune 500 companies.

During the first phase of cloud adoption, a company’s developers put workloads on AWS or Rackspace on their own, often without any corporate oversight. Now in phase two, C-level execs know that their companies have to make use of cloud resources but they also want controls and policies in place that govern those resources are used. That’s where Scalr comes in, he told Fortune.

Scalr is primarily a “policy engine” which works across clouds. Chief information officers and security specialists want to prevent the placement of sensitive data, say credit card information or private health records, in non-secure environments. And, they want resources to be tagged with information on who owns them and what their purpose is.

For those reasons there’s been quite a bit of funding flowing to cloud services companies. Cloudyn, for example, which monitors usage costs of Amazon and Microsoft clouds, closed $11 million in new funding last month; and Server Density, a UK-based startup that monitors server performance across cloud-based software applications, netted $1.5 million in seed funding..

Scalr, which claims customers including the FDA, NASA, Expedia EXPE , Samsung, and Accenture ACN , can monitor jobs running on Amazon Web Services EC2; Google Compute Engine, Rackspace rax OpenCloud, Microsoft Azure, CloudStack, and various flavors of OpenStack, an open-source cloud framework that many company’s have built their private clouds on.

OpenView partner Mackey Craven is now on Scalr’s board, joining Chris Kemp, the former NASA chief technology officer and one of the founders of the OpenStack cloud framework that’s been adopted by many companies as the foundation of their private cloud setups.
