Aryaka’s State of the WAN Report Reveals Building and Maintaining an SD-WAN is Complex

Aryaka published its third annual 2019 State of the WAN report that reveals SD-WAN, cloud and application performance challenges, priorities and plans for 2019 and beyond. When comparing this year’s results to the 2018 report, a pattern emerges: more respondents identified complexity, even surpassing performance, as the biggest challenge with their WAN. As applications and cloud connectivity become more complex, so do the networks required to support them. Organizations may recognize this, but don’t always have the expertise or resources to deliver on their digital transformation objectives.

The research on migration to SD-WAN concurs with Aryaka’s latest survey results regarding the complexities of managing the underlying WANs in enterprise networks,” said Erin Dunne, Director of Research Services at Vertical Systems Group. “We are seeing more enterprises choose managed SD-WAN solutions focused on providing dynamic WAN connectivity to ensure optimal end-to-end performance for all types of business-critical applications.”

Study Methodology

Thethird annual Global Aryaka 2019 State of the WAN study surveyed 795 global IT and network practitioners at companies across all verticals primarily headquartered in North America (57 percent), Europe (20 percent) and Asia—excluding China—(12 percent), and with up to 1,000 employees (31 percent), up to 10,000 employees (32 percent) and over 10,000 employees (24 percent). The survey asked respondents about their networking and performance challenges, priorities and their plans for 2019 and beyond.

What follows are a few of the key findings from this year’s report.

Cloud Models and New Applications Are Driving Digital Transformation

Most surveyed enterprises operate in highly distributed and complex IT environments. Over one-third have 20 or more branches around the globe. Half leverage five or more cloud providers or SaaS applications, and almost 15 percent have over 1000 applications deployed. These trends impact the enterprise’s ability to properly provision, optimize, troubleshoot, and secure their WAN and multi-cloud environments.

Network and Application Performance is Paramount

With lines of business moving at a much faster pace, the WAN needs to evolve to meet the needs of digital transformation. However, traditional architectures do not effectively enable a multi-cloud approach due to their misalignment with a cloud consumption model predicated on flexibility. This results in cost, complexity and performance challenges. 40 percent of those surveyed said cost was a challenge for them (7 percent higher than 2018). 35 percent said their challenge was around the high complexity, manageability and maintenance (14 percent higher than 2018). And 24 percent said they had concerns around slow access to cloud services and SaaS applications (a 3 percent decrease from 2018). With the limited visibility available, enterprises are split on the source of their application challenges, with 19 percent stating the branch, 23 percent the middle-mile, and 24 percent the application origin.

Unified Communications-as-a-Service (UCaaS) Challenges

One common complaint is UCaaS performance across traditional WANs due to latency and packet loss. Challenges include poor quality at 41 percent (an 11 percent drop from 2018), lag and delay at 31 percent (12 percent higher than 2018), and management at 28 percent (18 percent higher than 2018). Clearly, management is becoming a greater concern.

Innovation Drives a Better Experience

Traditional carriers and do-it-yourself (DIY) deployments are not equipped to handle the agility required for digital transformation. Solving slow application performance and managing vendors are the top time-sucks for IT organizations. 45 percent of respondents said slow application performance is leading to poor user experience in branch offices. 36 percent said slow application performance is leading to poor user experience for remote and mobile users (nine percent higher than 2018). And 28 percent said managing telcos or service providers is a nightmare (12 percent higher than 2018).

Managed SD-WAN is the Future

As organizations plan to the future, their top IT priorities are advanced security (34 percent), cloud migration (31 percent), IT automation (28 percent), and big data and analytics (28 percent). Yet traditional WAN and DIY SD-WAN solutions can’t always support these initiatives and based on the growing number of respondents who have issues with managing their telcos, the situation is only getting worse. A fully managed global SD-WAN solution promises to provide flexibility, visibility, enhanced performance and the cost control required in a cloud-first era. And, the characteristics that enterprises look for in any SD-WAN solution closely track their overall IT priorities – 47 percent are looking for cloud and SaaS connectivity, 43 percent advanced security, 37 percent WAN optimization and application acceleration, and 34 percent are looking to replace their MPLS network.

We are living in a complex multi-cloud 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. 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 organizations are at an inflection point: transform the WAN now or risk falling behind and losing out to competitors.
