Infonetics: ADC, WAN Optimization Markets Decelerate in Q3; Virtualization to Boost Growth Down the Road

Market research firm Infonetics Research released preliminary results for the application delivery controller (ADC) and wide area network (WAN) optimization markets from its 3rd quarter 2012 (3Q12) Data Center Network Equipment report. (Full report published December 7.)


"While ADCs and WAN optimization appliances posted modest revenue gains in the 3rd quarter, the pace of growth in these segments decelerated year-over-year," notes Sam Barnett, directing analyst for data center and cloud at Infonetics Research. “Top-line revenue growth in the ADC market is slowing due to the lower ASPs associated with virtual solutions versus their hardware-based counterparts, and saturation at the high end of the WAN optimization market is pressuring near-term growth.”

“That said,” Barnett adds, “We believe this will change as more virtualized solutions enter the mainstream, helping to restore higher levels of overall growth to the WAN optimization and application delivery controllers markets.”


  • Worldwide ADC revenue rose 5% in 3Q12 from 2Q12, but year-over-year (YoY) growth decelerated again and now stands at +6%, falling from +27% YoY growth in 3Q11
  • F5 continues to lead the pack in ADCs, capturing nearly half of 3Q12 revenue; Citrix and Cisco round out the top 3 market share slots
  • Cisco recently announced its intention to exit the ADC market, presenting an opportunity for F5 and Citrix to grow market share going forward
  • WAN optimization revenue grew 3% sequentially in 3Q12, but is down 4% from the year-ago 3rd quarter
  • Perennial leader Riverbed again dominated the WAN optimization segment in 3Q12, with almost 3/5 market share; Cisco remains solidly in 2nd place


Infonetics’ quarterly data center network equipment report provides worldwide and regional market size, vendor market share, forecasts, analysis, and trends for data center Ethernet switches (general purpose, purpose-built, and blade switches), ADCs, and WAN optimization appliances. Companies tracked include Alcatel-Lucent, Blue Coat, Brocade, Cisco, Citrix, Dell, F5, HP, IBM (BNT), Juniper, Radware, Riverbed, and others. To buy the report, contact Infonetics Sales:

I recently attended and was a speaker at the 4th International Internet of @ThingsExpo at the Santa Clara Convention Center. I also had the opportunity to attend this event last year and I wrote a blog from that show talking about how the “Enterprise Impact of IoT” was a key theme of last year’s show. I was curious to see if the same theme would still resonate 365 days later and what, if any, changes I would see in the content presented.
Apps and devices shouldn't stop working when there's limited or no network connectivity. Learn how to bring data stored in a cloud database to the edge of the network (and back again) whenever an Internet connection is available. In his session at 17th Cloud Expo, Ben Perlmutter, a Sales Engineer with IBM Cloudant, demonstrated techniques for replicating cloud databases with devices in order to build offline-first mobile or Internet of Things (IoT) apps that can provide a better, faster user e...
Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem"...
Culture is the most important ingredient of DevOps. The challenge for most organizations is defining and communicating a vision of beneficial DevOps culture for their organizations, and then facilitating the changes needed to achieve that. Often this comes down to an ability to provide true leadership. As a CIO, are your direct reports IT managers or are they IT leaders? The hard truth is that many IT managers have risen through the ranks based on their technical skills, not their leadership ab...
With all the incredible momentum behind the Internet of Things (IoT) industry, it is easy to forget that not a single CEO wakes up and wonders if “my IoT is broken.” What they wonder is if they are making the right decisions to do all they can to increase revenue, decrease costs, and improve customer experience – effectively the same challenges they have always had in growing their business. The exciting thing about the IoT industry is now these decisions can be better, faster, and smarter. Now ...

In this new da...
In today's enterprise, digital transformation represents organizational change even more so than technology change, as customer preferences and behavior drive end-to-end transformation across lines of business as well as IT. To capitalize on the ubiquitous disruption driving this transformation, companies must be able to innovate at an increasingly rapid pace. Traditional approaches for driving innovation are now woefully inadequate for keeping up with the breadth of disruption and change facin...

We all know that data growth is exploding and storage budgets are shrinking. Instead of showing you charts on about how much data there is, in his General Session at 17th Cloud Expo, Scott Cleland, Senior Director of Product Marketing at HGST, showed how to capture all of your data in one place. After you have your data under control, you can then analyze it in one place, saving time and resources.
