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.

Huawei Mate 20 unveils ‘higher intelligence’

The new Mate 20 series, launching in South Africa today, includes a 7.2″ handset, and promises improved AI.

Huawei Consumer Business Group today launches the Huawei Mate 20 Series in South Africa.

The phones are powered by Huawei’s densest and highest performing system on chip (SoC) to date, the Kirin 980. Manufactured with the 7nm process, incorporating the Cortex-A76-based CPU and Mali-G76 GPU, the SoC offers improved performance and, according to Huawei, “an unprecedented smooth user experience”.

The new 40W Huawei SuperCharge, 15W Huawei Wireless Quick Charge, and large batteries work in tandem to provide users with improved battery life. A Matrix Camera System includes a  Leica Ultra Wide Angle Lens that lets users see both wider and closer, with a new macro distance capability. The camera system adopts a Four-Point Design that gives the device a distinct visual identity.

The Mate 20 Series is available in 6.53-inch, 6.39-inch and 7.2-inch sizes, across four devices: Huawei Mate 20, Mate 20 Pro, Mate 20 X and Porsche Design Huawei Mate 20 RS. They ship with the customisable Android P-based EMUI 9 operating system.

“Smartphones are an important entrance to the digital world,” said Richard Yu, CEO of Huawei Consumer BG, at the global launch in London last week. “The Huawei Mate 20 Series is designed to be the best ‘mate’ of consumers, accompanying and empowering them to enjoy a richer, more fulfilled life with their higher intelligence, unparalleled battery lives and powerful camera performance.”

The SoC fits 6.9 billion transistors within a die the size of a fingernail. Compared to Kirin 970, the latest chipset is equipped with a CPU that is claimed to be 75 percent more powerful, a GPU that is 46 percent more powerful and an NPU (neural processing unit) that is 226 percent more powerful. The efficiency of the components has also been elevated: the CPU is claimed to be 58 percent more efficient, the GPU 178 percent more efficient, and the NPU 182 percent more efficient. The Kirin 980 is the world’s first commercial SoC to use the Cortex-A76-based cores.

Huawei has designed a three-tier architecture that consists of two ultra-large cores, two large cores and four small cores. This allows the CPU to allocate the optimal amount of resources to heavy, medium and light tasks for greater efficiency, improving the performance of the SoC while enhancing battery life. The Kirin 980 is also the industry’s first SoC to be equipped with Dual-NPU, giving it higher On-Device AI processing capability to support AI applications.

How Quantum computing will change … everything?

Research labs, government agencies (NASA) and tech giants like Microsoft, IBM and Google are all focused on developing quantum theories first put forward in the 1970s. What’s more, a growing start-up quantum computing ecosystem is attracting hundreds of millions of investor dollars. Given this scenario, Forrester believes it is time for IT leaders to pay attention.

“We expect CIOs in life sciences, energy, defence, and manufacturing to see a deluge of hype from vendors and the media in the coming months,” says Forrester’s Brian Hopkins, VP, principal analyst serving CIOs and lead author of a report: A First Look at Quantum Computing. “Financial services, supply-chain, and healthcare firms will feel some of this as well. We see a market emerging, media interest on the rise, and client interest trickling in. It’s time for CIOs to take notice.”

The Forrester report gives some practical applications for quantum computing which helps contextualise its potential: 

  • Security could massively benefit from quantum computing. Factoring very large integers could break RSA-encrypted data, but could also be used to protect systems against malicious attempts. 
  • Supply chain managers could use quantum computing to gather and act on price information using minute-by-minute fluctuations in supply and demand 
  • Robotics engineers could determine the best parameters to use in deep-learning models that recognise and react to objects in computer vision
  • Quantum computing could be used to discover revolutionary new molecules making use of the petabytes of data that studies are now producing. This would significantly benefit many organisations in the material and life sciences verticals – particularly those trying to create more cost-effective electric car batteries which still depend on expensive and rare materials.
