  • Rocana has built a platform that can handle very large volumes of operations data, a capability that sets it apart from competitors and should appeal to large enterprises… In delivering automation capabilities relatively early compared with rivals, Rocana can lead the way in demonstrating how automation can improve performance for businesses.Nancy Gohring, 451 Research Senior Analyst
  • Today’s CIOs and IT leaders are increasingly responsible for driving business outcomes in a world of ever increasing data volumes and data sources. Rocana was selected for the Ventana Research Technology Innovation Award for its innovative approach to achieve total visibility across IT and business data, using big data and advanced analytics to help IT teams identify anomalies, improve customer experience, and increase security and compliance.David Menninger, Ventana Research Senior Vice President and Research Director
  • Companies that adopt modern infrastructures are learning that their IT operations generate huge amounts of potentially valuable data. But many traditional IT tools aren’t able to effectively scale so that businesses can efficiently retain and analyze that information. The result is a missed opportunity for enterprises to glean important business and IT insight from their operational data.Nancy Gohring, 451 Research Senior Analyst
  • Wikibon research shows that IT organizations routinely fall into the trap of relying on automation tied to specific products, each in control of its own data, which can severely limit operational visibility. It's time for companies to adopt approaches that increase business opportunities by applying operational data across platforms to multiple classes of hard problems.Peter Burris, Wikibon Chief Research Officer
  • Operational visibility is a tricky business. Having that level of data oversight really can make a difference in how IT can contribute to the top line. Contributing to the business – rather than just supporting the business – should be the goal of IT in terms of relevance in today's environment.Dr. Alea Fairchild, Blue Hill Research Entrepreneur-in-Residence
  • With rising complexity you need to make sense of data - operational analytics is the key.John Rakowski, Forrester Analyst and Advisor
  • IT analytics lets you manage this complexity by turning Big Data inward.Jean-Pierre Garbani, Forrester VP and Principal Analyst
  • As scale and complexity increase with companies moving to the cloud, to microservice architectures, and to transient containers, monitoring needs to go back to school for its Ph.D. to cope with this new generation of IT.Donnie Berkholz, Research Director, 451 Research
  • An application that makes it easier to keep data centers up and running could become the 'killer app' for Hadoop because as companies become more dependent on large-scale customer-facing apps, it’s critical that they be reliable and scale predictably. Donald Fischer, General Catalyst Venture Partner
  • The operational data explosion has sparked a sudden and significant increase in demand for IT operations analytics (ITOA) systems.Will Cappelli, Gartner Research VP
