How SD-WAN closes performance gap for business

Published

on

Riverbed Technology sub-Saharan Africa country manager WIMPIE VAN RENSBURG outlines how SD-WAN technology helps improve the performance of enterprise applications.

As an increasing number of organisations migrate to the cloud, the gap between the needs and expectations of the business and IT’s ability to deliver is growing. With apps, data and users scattered across branch offices and other remote locations, IT is struggling to deliver the application performance businesses need to remain productive. In fact, the Riverbed Global Application Performance Survey 2015 shows that while 98 per cent of executives believe that enterprise application performance is critical to achieving optimal business performance, 89 per cent say poor performance of enterprise applications negatively impacts their productivity on a regular basis.

So what is the cause of this performance gap and how can businesses close it? Chances are IT is wrestling with a complex, inflexible WAN – a wide area computer network, to interconnect their diverse application workloads to their distributed workforce. In fact, the WAN is likely the IT infrastructure’s weakest link, and it’s preventing it from meeting the dynamic demands of the modern enterprise.

Business is speeding up, and IT needs to keep pace. Organisations need SD-WAN (software-defined wide area networking), and here’s why.

Today’s network challenges

Driven by the rapid globalisation of the business world, the WAN is becoming more and more dispersed every day. Remote workers are scattered across the globe — in branch offices, construction sites and coffee shops, to name just a few — and they all demand flawless network performance to stay productive.

What’s more, end users are depending on an ever-expanding catalogue of applications, some of them cloud based. And if the apps don’t work, neither do your end users. Many of them are even adopting independent apps which are not explicitly approved by the organisation — a phenomenon called “shadow IT”– in order to get work done in a timely manner.

As a result, today’s networks are more unruly than ever. Businesses need a new day in networking, and they need it now. But why?

The trouble with traditional MPLS WANs

Old-school WANs are having a hard time meeting the demands of the modern business. A network based on MPLS links can be expensive but also time-consuming. Traditional MPLS networks rely on operation paradigms that were defined more than 15 years ago at a time were the pace of changes was a matter of months not a matter of days.

The trouble with hybrid WANs

Many organisation are today considering reducing the costs of MPLS based networks using more affordable Internet links to create a hybrid WAN. But in many cases, what you save in costs you sacrifice in security and control.

Moreover, a significant rise in encryption and cloud technologies can cut into network visibility, making it next to impossible to know when and where a performance problem is occurring.

All the while, the pressure is mounting on IT, and the business is expecting you to act at the drop of a hat:

  • They need you to deploy a new app that will totally change your traffic profile (and you need to maintain control), today
  • They need you to provision a new branch office on the other side of the world with the right apps and data, and make sure mission-critical apps are performing flawlessly for all users no matter what, today

The list goes on. But unfortunately, the state of your network has you handcuffed. And this is where SD-WAN comes in.

What SD-WAN can do for businesses

To put it simply, SD-WAN allows businesses to control their network from a single, easy-to-use, intuitive command centre. At its core, SD-WAN enables them to make on-the-fly adjustments to network performance and application delivery, in order to meet the businesses ever-changing needs.

By leveraging software-defined networking (SDN) principles, designed to make networks more flexible and agile, SD-WAN enables organisations to direct traffic and deploy network services across a WAN from a centralised location — without any mess or hassle. Instead of the old router-based model, which required IT managers to make intensive CLI-based code changes to routers, SD-WAN allows network services and policies to be assigned to different locations, users, and even apps — all with just a few clicks.

What’s more, an app-centric SD-WAN will automatically identify the applications in the organisation’s network and group them into logical categories based on business criticality, and even apply network-service policies to those categories based on built-in best practices.

These benefits offer IT a broad range of possibilities. Organisations can automatically route voice traffic to their highest-quality network paths. They can quickly segregate employee traffic from that of partners and customers. They can send recreational Internet traffic through the most rigorous firewalls. And more. And IT can do it all simply and centrally, without breaking a sweat.

All in all, SD-WAN makes networks more flexible and agile than ever, which, in turn, allows you to meet business needs efficiently and effectively.

As selfie cameras rise, so must selfie etiquette

Selfies were once a sign of narcissism or self-obsession. Now they are the new normal, writes ARTHUR GOLDSTUCK.

Published

You can blame Oxford Dictionaries for making the “selfie” respectable. After all, being named Word of the Year, as it was in 2013, does tend to soften some of the self-consciousness in this most self-conscious of actions.

Once seen as a symbol of narcissism and self-obsession, it is now the new normal, to the extent that most smartphones are sold on the basis of the front camera. Or, as that feature is now almost universally named by manufacturers, the “selfie camera”.

I was one of the hold-outs, having a near-allergy to the selfie. I still resist, but succumb more often than I would like. The reason for continued resistance is that it remains a big leap from the word becoming respectable to the action itself shedding its narcissistic image. 

For most, it’s already happened, and for that you can blame Ellen DeGeneres. She  choreographed the most famous group selfie yet at the 2014 Oscars, when she roped a bunch of actors into a group selfie, using the then-new Samsung Galaxy S5 smartphone. Her tweet of the photo became what was then the most retweeted posting ever on Twitter, and was estimated to have been worth a million dollars in marketing value to Samsung.

Ironically, it was Samsung’s up-and-coming challenger, Huawei, that came up with a new word for this type of selfie: the “groufie”. Thanks to an 8 Megapixel front camera on the new Huawei Ascend P7 camera that year which took the highest quality selfies – and groufies – possible on a smartphone at the time.

It didn’t end there, and selfies and groufies have morphed into variations like selfscapes (selfie in a landscape), skyfies (selfies from the air, using remote controlled devices) and jerkies (selfies to make an idiot out of yourself). I invented all of those on the fly, so it’s easy to imagine a new word emerging for every type of selfie.
