CW: Your recent acquisition of Zeus Technology and Aptimize puts you in direct competition with established vendors in the application delivery space like F5 and Citrix. How do you position Riverbed, given its traditional focus on WAN optimization?

Batra: It is true that we started out with a WAN optimization offering and it remains our flagship product. However, like any other company, we've gradually brought in adjacent technologies to create a platform. Our platform enables infrastructures to be optimized, drives applications to perform better, and delivers apps in the right manner. We also focus on application firewalls, web-content optimization, and application-aware network performance management

Riverbed is a performance platform company. Yes, we did begin with WAN optimization, but that was just a part of the performance enhancement portfolio. In our continuing conversation with the customer, it was very evident that there was a need to have a performance platform that would take care of a lot of other things. As a result, we looked at what we should have as a set of competencies, and obviously the virtual ADC is a growing area. If the appliance-based ADC market is growing at 15 percent, then the growth rate of the virtual ADC market is more than 40 percent. With the Zeus acquisition, we became the leader in the virtual ADC space. Aptimize, which is a web-content optimization company, further enhances this portfolio.

The companies that you mentioned are in different areas, but we encompass the whole platform. Besides, we are the only player that focuses on virtual ADCs. The market is, otherwise, appliance-based. According to industry reports, the virtual ADC market will grow at a fast rate, considering the current consolidation scenario in the datacenter.
