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.

Welcome to world of 2099

The world of 2099 will be unrecognisable from the world of today, but it can be predicted, says one visionary. ARTHUR GOLDSTUCK met him in Singapore.

Futuristic structures tower over the landscape. Giant, alien-looking trees light up with dazzling colours amid the hundreds of plant species that grow up their trunks. Cosmetic stores sell their wares via public touch-screens, with products delivered instantly in drawers below the screens.

This is not a vision of the future. It is a sample of Singapore today. But it is also an inkling of the world we may all experience in the future.

Singapore was the venue, last week, of the World Cities Summit, where engineers, politicians, investors and visionaries rubbed shoulders as they talked about the strategies and policies that would enhance urban living in the future.

As part of the Summit, global payment technologies leader Mastercard hosted a small media briefing by one of Singapore’s leading thinkers about the future, Dr Damian Tan, managing director of Vickers Venture Partners. The company’s slogan “We invest in the extraordinary,” offers a small clue to Tan’s perspective.

“We look as far forward as 2099 because, as a venture capital firm, we invest in the long term,” he tells a group of journalists from Africa and the Middle East. “Companies explode in growth because there is value in the future. If there is no growth, they won’t explode.”

The big question that the Smart Cities Summit and Mastercard are trying to help answer is, what will cities look like in the year 2099? Tan can’t give an exact answer, but he offers a framework that helps one approach the question.

“If you want to look at 81 years into the future, and understand the change that will come, you need to double that amount and look into the past. That takes us to 1856. The difference between then and now is the difference you can expect between now and 2099.”

Street art goes electric

Kaspersky Lab and British street artist D*Face have unveiled the first-ever “art helmet” design at the Formula E finale for electric cars in New York.

Published

The ‘Save The World’ helmets will be raced by DS Virgin Racing’s drivers, Sam Bird and Alex Lynn, as they traverse the New York street circuit during the final races of the Formula E season.

The announcement signals the first art helmet by a Formula E team, continuing the heritage of art in motorsport and the cybersecurity brand’s commitment to contemporary art, creativity and innovation. D*Face took inspiration from Kaspersky Lab’s tagline, “A Company To Save The World”, and hopes that his colourful work will inspire people to take positive action.

D*Face will announce his first-ever art car design with a custom-made livery for the DS Virgin Racing Team. Its design will be released at the “Art Goes Green” event after Saturday’s race. The helmets and art car are the latest installations in the “Save the World” collection, following a major permanent public mural that was installed in Brooklyn, New York, in May.

D*Face, whose real name is Dean Stockton, said: “It is exciting to work with Kaspersky Lab on this project and create art with a real message of hope for a better future. After all, this is our world and we need to look after it. It will take every one of us to make a real lasting, impactful change. I love the mentality of the DS Virgin Racing Team and that of Formula E by showcasing sport in a way that doesn’t harm the environment, but is still just as exhilarating and fun.

“It is time for us all to stand together and make a change… be that stopping data steals, climate change, plastic waste or using damaging fuels. I want everyone to make a pledge to do one thing that will help make a change.”

As a sponsor of DS Virgin Racing Team, Kaspersky Lab is responsible for protecting the team’s devices against cyber threats. The company sees the technical environment in the global sport of Formula E as the next frontier in furthering its research and development of new technologies to keep vehicles secure in the digital world.

Sylvain Filippi, Managing Director at DS Virgin Racing, said: “The whole team fully supports this great initiative and our thanks got to Kaspersky and D*Face for their collaboration. It’s an honour to have such an innovative artist bring his talents to bear in our team ahead of the season-finale; the car, drivers’ crash helmets and mural all look amazing.”

Aldo Fucelli Pessot del Bo, Head of Global Partnerships and Sponsorships at Kaspersky Lab added: “There is a need for innovation on a global scale, both in contemporary art and in the fast-growing sport of Formula E. Now, for the first time ever, Kaspersky Lab is proudly bringing together the two sectors in an effort to Save the World and unleash creativity, encourage freedom of expression and further innovation.”
