Cisco’s recent acquisition shows exciting times ahead for the lead players in the cloud Wi-Fi space

November 28th, 2012

Barely two weeks after I posted my last blog discussing benefits of the true cloud Wi-Fi over the controller over WAN architecture using Cisco FlexConnect as example for the latter; news of Cisco acquiring Meraki broke out. I got a kick out of it since it showed that my inferences on Cisco FlexConnect and other controller centric offerings were dead on spot, that they can never become real cloud Wi-Fi by incremental touchups and jargon experimentation. I also got a kick out of its timing — 1.2B acquisition barely 2 weeks after I wrote that post! There are several takeaways for the future of cloud Wi-Fi from this big event. First and most obvious is that the cloud Wi-Fi market is expanding rapidly. Another takeaway is that for the vendors already committed to the controller centric WLAN architecture, migration to cloud architecture is not incremental, but it is disruptive. Cisco could not do the migration in-house even after trying for few years with incremental changes like REAP, H-REAP, ELM, and FlexConnect. As I said in my last blog, cloud Wi-Fi is not about throwing controller over WAN, but is needs to be architected differently from the bottoms up. Finally, it also shows that with the standardization of access point platforms, differentiation in mainstream enterprise Wi-Fi will come from innovations in the application space such as network management, security, and integration with other services.

AirTight envisioned value of the cloud managed Wi-Fi solutions way back in 2008; when it was the first to launch wireless intrusion prevention (WIPS) and wireless PCI compliance solutions from the cloud (cloud used to be called SaaS at that time). It saw wholehearted acceptance from customers for Wi-Fi security and compliance applications. Having seen the benefits of the cloud Wi-Fi security offering, those same customers then wanted Wi-Fi access bundled with security in the AirTight cloud offering and AirTight answered their call in 2010. AirTight’s cloud managed Wi-Fi access with built in PCI compliance, saw tremendous success in the market. Riding on this second wave of success in the cloud strategy, AirTight then launched cloud managed enterprise grade Wi-Fi access with its highly acclaimed, absolute best-in-class WIPS buit into it.

Due to strong security posture, extreme scalability, and unique management capabilities, AirTight Cloud Services™ are not just for the midmarket, but also fit very well into scale many times as big. No wonder, organizations even as large as multiple 10,000’s distributed locations have selected AirTight cloud Wi-Fi over all competing Wi-Fi solutions! I am excited to see the cloud Wi-Fi market ignited by Cisco right at the time when AirTight has reached great level of maturity on its cloud Wi-Fi offerings over all these years.

Is your cloud Wi-Fi genuine, or is it controller over WAN imitation?

November 7th, 2012

With rising popularity of the cloud Wi-Fi in the distributed Wi-Fi deployments, there is also an attempt to pass off the legacy controller technology as the cloud Wi-Fi by deploying conventional controllers over the WAN. Realizing that it is infeasible to deploy many smaller controllers in the distributed Wi-Fi deployments such as retail, remote offices, etc., the controller over WAN architecture deploys bigger controllers at the HQ and calls it a cloud Wi-Fi. However, the controller over WAN Wi-Fi does not measure up to the true cloud Wi-Fi for many reasons as outlined below. We will use example of Cisco’s controller over WAN architecture to illustrate these differences. Earlier, Cisco called it H-REAP and ELM, now it calls it FlexConnect, but does changing terminology get controllers to measure up to the true cloud? Let us find out. Read more…
