#IWANWed: Harness the Power of Web Within the Enterprise Branch

Cloud Web Security AAG ImageIn the ever-changing world of enterprise branch environments, a high number of businesses are planning to migrate their WAN to the Internet. To be exact, Nemertes Research (Benchmark 2012–13 Emerging WAN Trends) estimates that number to be close to 50%.  That’s 50% of businesses migrating to Internet for WAN.

And why is that happening? Enterprises are trying to optimize their WAN to increase ROI. Internet has become a much more stable platform, offering significant price-to-performance gains. Thus, the growth of new cloud traffic, high bandwidth applications, and video can be easily load balanced across multiple WAN lines, one of which or both can be Internet links. Some of the enterprises go even further and enable local Internet breakout from the branch. Not only does it eliminate the need to unnecessarily backhaul the traffic to the corporate HQ or data center, but also helps to free up the precious WAN bandwidth for critical business related applications. This enables enterprises to provide guest Internet access within the branch and then slowly offer the same services to corporate users, both for trusted public clouds applications and general Internet access.

IWAN Wed: What’s more important? Uptime or Cost?

Screen Shot 2014-07-01 at 5.25.06 PM“Location, Location, Location” is what you need to keep in mind for real estate in the physical world.  But in today’s
enterprise environment where everything is virtual and many critical apps are in  the data center or cloud, the most important thing is connectivity.

So welcome to the era of connectivity, connectivity, connectivity!

As connectivity is so important, what can we do to ensure the uptime of the branch WAN connectivity without increasing costs?

IWAN Wed: The Case for Direct Internet Breakout at Branch and IWAN

Simplify Branch Security with ISRCloud services and SaaS applications is enabling customers to accelerate their business processes and improve employee productivity while lowering their total IT spending. The Cisco IWAN solution is helping organizations adopt cloud applications with an improved user experience by enabling local internet breakout from the branch environment, thus helping eliminate the need to backhaul internet-bound traffic across the WAN link. This helps provide the user improved experience through lower latency for not only internet applications, but also free up bandwidth for application on the WAN link. The reduced WAN link usage also means lower IT spending those links.

However, a study commissioned by Cisco during Jan’14 from 641 customers from US and Europe on their MPLS usage and adoption of local internet breakout found that 68% of the customers responded that enabling direct internet access was an organizational focus for them.  However, 54% of the total respondents reported that lack of sufficient security at the branch environment hindered them from enabling local internet breakout at the branch. This was ranked as the #1 reason to not enable Direct Internet Access at branch sites.

Unlock the Hidden Capabilities Your Cisco Integrated Services Routers

If you have a Cisco Integrated Services Router (ISR) in your branch – which most companies do – you won’t want to miss the April 23rdwebinar on hidden capabilities of the ISR.

These routers are the Swiss army knife of networking, and come loaded with so many features that it is almost impossible to know all of them. I cannot count the number of times I found myself saying “wow, I didn’t even know that the ISR can do that.” This is because IOS is a very mature operating system with about 30 years of customer experience and feature enhancements. I don’t think that there is any other company in the world that can say that they have 30 years of customer experience in this field.

Routing has evolved tremendously over those years. We’ve moved from access routing to full integrated services to an all-in-one converged branch solution. Our leadership in this space was recognized just two weeks ago, when a new Cisco routing solution won the Best of Interop for Networking. Read More »

IWAN Wednesday: (Webinar) Enhance your branch with UCS E-Series

For the last 3 weeks, my colleagues have written on the topic of IWAN and its various components.  Ido wrote about the basics (and more) about IWAN, Kiran on how to get twice the bandwidth with PfR, and Hector on how Glue Networks improves the IWAN experience for IT.   As the name suggests, the ‘WAN’ in Intelligent WAN is a very important element but we can’t forget why we need an intelligent WAN – the branch or store that sits on the other side.  It’s the place where 80% of employees of enterprises reside and where content explosion is happening with cloud applications, video training, and other business applications need to be delivered to.  So it would be an understatement to say the branch architecture and how applications are delivered and hosted is important.
