Zenoss, the leading provider of unified IT operations software for physical, virtual, and cloud-based IT infrastructures, today announced a record 2012, achieving 43 percent annual revenue growth over 2011 and adding 50 new enterprise customers. The company also experienced record sales and renewals to existing customers including Rackspace, Sungard, Telstra and VMware.

The modern datacenter is evolving to become more elastic, nimble and cost efficient. In pursuit of the promise of business agility, data centers are deploying increasing levels of virtualization and embracing cloud-computing technologies. Virtualization reduces the friction of change within the IT infrastructure by freeing up applications from the physical constraints of computing, networking and storage. Zenoss helps organizations manage their increasingly complex IT infrastructures, ensuring the seamless delivery of critical IT services and enabling higher levels of business agility and IT cost efficiency.

"In the past decade, the IT infrastructure space has experienced a dramatic evolution. A new era of software-defined IT infrastructure is emerging, and a new class of IT monitoring solution is needed to manage the modern datacenter," said Bill Karpovich, CEO and Co-Founder of Zenoss. "Our growth in 2012 is evidence that we are providing the solutions our customers need to manage the modern datacenter."
