Mo’ Traffic, Mo’ Problems: How to Turbo Charge Business Growth across the WAN

Today’s successful business leaders recognize that mobile apps, immersive web content and high definition video are all essential to elevating customer engagement and empowering employees – not to mention growing revenue and increasing productivity.

But as the Internet of Everything becomes a reality, and introduces seemingly endless opportunities to connect more people, more devices, and more content across a highly distributed network – global Internet traffic is expected to triple by 2017 (Cisco VNI, 2013), and frankly, today’s WAN architecture is beginning to show its age. Ultimately, our customers will need to rethink their current network to accommodate the increase in traffic.

Those deployments will be critical for in-branch revenue growth in verticals like retail – where a connected digital experience for customers and employees can deliver superior performance for a host of cloud applications including eCatalogs, Omni-channel engagement, in store mobile apps, guest Wi-Fi and product demos. This trend also extends to other verticals: Read More »

IWAN Wed: What is Intelligent WAN?

Imagine that you have several branch offices that are using WAN demanding applications like Salesforce.com, Office 365, Virtual Desktops, Video Teleconferencing and more.  You are using those expensive MPLS/VPN WAN connections as you don’t want to risk it and probably because when you started to work there it was already there and … why mess around with something that is working, right?  Normally I would agree with that but when IT budgets are shrinking and the network needs to step up and support those business critical apps, there is no other way but to innovate.

At any given time your network carries information from LAN to WAN and vice versa, some is important and some is less important. In many cases as a network admin you don’t have the visibility to distinguish between them, so what do you do when those critical apps are starting to act up? Usually the answer will be to buy more WAN bandwidth and that will give the apps and the user experience behind them some breathing space. But all you’re doing is buying time.  Buying time never solves the problem because you will need to treat the symptoms again in a few weeks or months.

However, you can solve the problem and not just treat the symptoms using Cisco Intelligent WAN or IWAN for short.

Delivering Application Optimization for Office 365

We in IT are faced with many challenges from our end users.  From IT costs to application performance, while always keeping an eye on our network security posture.  This reminds me of a sign on the wall of my auto mechanic’s shop: Good, Fast, Low-cost. I was always told I am allowed to pick only two.  I would of course question him, “why cant I have something with high quality, on time, and within budget?”  This always made him smile, but he still told me I could only pick two.

So back to our IT challenges: Cost, Performance, and Security. Application performance is something we can all see, feel and touch. When thinking about performance, we need to also consider where these applications are coming from.  Looking at applications like Microsoft’s Office 365, we are seeing mission critical applications from outside our data centers being delivered as Software as a Service (SaaS) solution. Does this matter to our end users?  They sit at their PC’s, Tablets, Mac’s, etc. and know when something is not going fast enough.  Their expectations are growing; they always expect the best performance. If they don’t feel their Outlook e-mail is opening fast enough or that the saving of their PowerPoint file is taking too long, they do not hesitate to let us know.  And oddly enough, everyone just assumes it is the network.  So not only do we need to think about our networks, but the Internet performance as well.

Data Center Replication: WAN Optimization vs. Bandwidth Upgrade

During the past years WAN optimization devices were used to optimize end-user traffic mainly. Employers connecting to remote applications can achieve better user experience if a couple of WAN optimization are deployed. Typically web applications, file sharing and email can be well accelerated: end users can increase their productivity with a little investment.

On the other side providers usually offer free bandwidth upgrade during a contract renewal.

So the question are:

  • Can Data Center replication take advantage of WAN optimization?
  • Can a Bandwidth upgrade always supersede WAN optimization?

The answers are, as always: it depends. Read More »

Momentum is growing for the Cisco ISR-AX!

It has been a couple of weeks since its launch and we are seeing lots of interest in the Cisco ISR-AX!  I have been hearing from customers, partners and folks  worldwide about how they are using the new ISR-AX platforms now and get a router, VPN, firewall, intrusion prevention, cloud/web security, AVC (NBAR2, QoS, NetFlow, Media Monitoring, PfR) and WAN optimization (WAAS) all in one box for less than the cost of just an alternative WAN Optimization appliance.  For WAN optimization with WAAS that is less than $1 per WAN optimized connection with ISR-AX!

Anyway, I’ve gotten lots of questions since the launch, so I grouped them and wanted to share the top 4: Read More »
