In its latest yearly survey of the wide area network (WAN) industry, cloud-first WAN provider Aryaka has revealed that network complexity and its resulting impact on performance are now the top blockers to WAN implementation.

\n\n

The fourth annual global State of the WAN report surveyed 1,031 global IT and network practitioners, with 238 of these respondents based across Europe. Almost half of the sample had 100-1,000 employees, a third employed 1,000-10,000 and 15% had fewer than 100.

\n\n

In addition to the top-line finding of dealing with complexity and performance, the study also highlighted that cost had become less of an issue for respondents, who also cited significant investment in automation, security, cloud connectivity and the potential of 5G.

\n\n

Drilling deeper into the pressing issues for firms, Aryaka found that as the number of remote workers increases across the globe, productivity and remote application performance have become more important for organisations across Europe, the Middle East and Africa (EMEA).

\n\n

Some 45% of UK businesses noted that slow application performance led to a poor user experience for remote and mobile users, and that it was a significant issue faced by IT and support teams. Accessing and integrating cloud and software-as-a-service (SaaS) applications was one of the most pressing issues for UK IT departments, cited by 39%.

\n\n

With a third of UK organisations regularly using in excess of 500 applications, finding a solution to application performance issues has become urgent for UK businesses. While an agile and secure WAN could address these issues, WAN management was still problematic.

\n\n

The survey showed that lack of adequate WAN security and the slow performance of on-premise applications were the top issues faced by UK organisations, cited by 33%. A similar number pointed to complexity in managing and maintaining the WAN, along with a lack of visibility into the WAN, as additional challenges.

\n\n

Looking at the new priorities and indeed new needs of UK businesses, Aryaka discovered that firms regarded 5G as the most significant network initiative ahead of them, with 43% declaring 5G investment a priority. At the same time, UK organisations were investing in big data and analytics (42%), IT automation (41%) and cloud/SaaS migration (40%). Organisations were also showing a strong interest in networking initiatives such as cloud and SaaS connectivity upgrades (39%) and cloud-based network management (37%).

\n\n

Another interesting discovery was businesses were less worried about the cost of implementing and maintaining the WAN, something Aryaka attributed to the drive towards improved networking. In 2018, 40% of respondents across Europe cited high costs as the main concern. In 2019, this number fell to just 14% in the UK and 12% in Europe – lower than the global average of 16%. This, said Aryaka, reflected a growing market maturity and a better understanding of return on investment in SD-WAN/WAN transformation projects.

\n\n

Yet the study also made clear that the adoption of SD-WAN was not without its hurdles. The report revealed fears of increased complexity when deploying SD-WAN – with 36% citing this as the top barrier to adoption. A similar percentage of UK IT managers also stated the technology was “too new”. The third barrier to SD-WAN adoption in the UK was a lack of the right skills for 33% of respondents.

\n\n

That said, SD-WAN was fundamentally gaining ground in the UK especially. Two-fifths of organisations were gathering information about the technology, and 30% were already evaluating suppliers. UK organisations were also demanding more from their SD-WAN solutions. Just over two-fifths (42%) in the UK were seeking cloud/SaaS connectivity, while 41% wanted application acceleration and WAN optimisation. Should they deploy one, UK respondents stated they would choose a telco- or MSP-provided option (32%) over an SD-WAN supplier (24%).

\n\n

Aryaka also warned that companies should avoid losing focus on security, with 40% stating security breaches as one of the main drains on European IT teams. Aryaka wondered whether this was why most respondents – 55% in Europe and 54% in the UK – said they would opt for a best-of-breed approach to SD-WAN security, with a managed firewall solution demanded by an overwhelming majority of 86%.

\n\n

Assessing the findings of the report and what it meant for the business environment going forward, Aryaka’s chief marketing officer, Shashi Kiran, said: “We are living in a complex multicloud and multi-SaaS application world. As global enterprises continue to innovate by embracing new technologies and migrating to the cloud, they also face new challenges, and the network is increasingly a strategic asset.

\n\n

“Whether it’s an increasing number of global sites through expansion, poor-performing cloud-based applications, increasing costs, or the time it takes to manage multiple vendors, many organisations are at an inflection point – transform the WAN now or risk falling behind and losing to competitors.”

Software-Defined Wide Area Networks (SD-WAN) is a great tool for enterprises looking to get more from their networks. It is a software approach of the WAN management. By creating a better way for connectivity, SD-WAN is helping solve the problem of how to keep networks up and running in a world where they only keep getting vaster and more convoluted. And SD-WAN helps reduce the operating costs with the independance of the links to MPLS, 3G/4G LTE, ect. SD-WAN combined with IoT can be a powerful combination and it is increasingly considered when designing network architectures and strategies for the Industrial IoT. But it’s important to take care when implementing this tech.

\n\n

Don’t Get Too Technical

\n\n

When selecting and implementing an SD-WAN for an enterprise, there can be a strong temptation to get wrapped up in technical specs. Professionals in charge of decision-making might end up obsessing over certain capabilities, but then miss the greater picture.

\n\n

The purpose of SD-WAN is to bring a greater level of connectivity, reliability, and control to modern networks. While this is certainly going to require certain levels of technical capabilities, don’t let yourself miss the forest for the trees. It’s often wise to check out third-party companies that offer SD-WAN and a bundle of other network assets as a service. This can simplify and improve everything relating to your enterprise’s SD-WAN architecture.

\n\n

Don’t Overlook Security Overlaps

\n\n

Implementing SD-WAN is supposed to be a relatively intuitive process despite its certain inherent layers of complexity. But just getting your enterprise’s SD-WAN up and running doesn’t ensure that it’s where it needs to be.

\n\n

Migrating from your old network structure to SD-WAN can lead to certain stones being left unturned. This can spell major problems when dealing in network security. Sometimes enterprises will even opt for a certain SD-WAN product based on claims that it can address current network security issues. Double-check these kinds of claims before adopting any new services, as a wrong move here can lead to major vulnerabilities.

\n\n

Ensure Optimal Performance Before Rollout

\n\n

Performance is one of the most critical elements to deploying SD-WAN within an enterprise. Without WAN optimisation, organisations can suffer from disordered and inefficient network traffic. This poses big issues for the enterprise as a whole, which flourishes on efficiency. But it’s also a big drawback for end-users, who won’t be happy with degraded performance.

\n\n

Look for SD-WAN service providers that offer optimal network path selection along with the ability to prioritise resources. By having these features, enterprises can ensure they don’t lose capabilities when making the switch to SD-WAN.

\n\n

Predict and Plan for Issues

\n\n

Things happen. Even the most careful and conscientious enterprises are going to run into issues from time to time. The best way to overcome these roadblocks isn’t to ignore them, but to plan.

\n\n

A lot of preparation needs to go into making the switch to SD-WAN. People are going to need to receive training and education on new procedures and protocols. Critical players need to map out exactly how the new SD-WAN infrastructure will work along with what was previously there. Furthermore, there needs to be action plans for in case things go wrong. Doing these things preemptively, as opposed to on the fly, will allow organisations to pivot along with whatever issues arise.

\n\n

Don’t Be Too Cheap

\n\n

Enterprises are always looking for ways to be more efficient. Sometimes that means saving money by going for a less-pricey product. However, there are also instances when doing this can backfire. SD-WAN implementation is one of those examples.

\n\n

You’re looking for a product that’s going to manage your organisation’s vast, sprawling networks full of sensitive, valuable information. Do you really want to trust that to the lowest bidder? Consistency and features such as encryption and real-time controls are important for keeping an organisation’s data secure. Skimping here can make the whole endeavor a disaster.

\n\n

Some analysts are predicting the SD-WAN market could experience a 5-year annual growth rate topping 40% and hitting $4.5 billion by 2022. That’s pretty compelling evidence for how much SD-WAN is becoming engrained in enterprise network security today. Knowing what mistakes to avoid with SD-WAN can make all the difference in its implementation.
