How do you imagine connectivity across the enterprise? Probably, it should be supported by various robust software solutions covering security, data transfer, access control, and other matters. But the desire to simplify the processes made prominent telecom vendors like Apcela and Aryaka launch an all-in-one cloud-based product for these purposes.

SD-WAN as a Service solutions are capable of ensuring uninterrupted connections inside enterprises. Their apparent benefits, like app usage optimization, data protection, and efficient traffic management, made them one of the most demanded technologies of recent years. Following Gartner, by 2024, to enhance agility and support for cloud apps, 60% of enterprises will implement SD-WAN compared with about 30% in 2020.

Here, you will explore the SD-WAN as a Service from the business perspective, diving into its evolution, features, and pros helping enterprises operate smoothly under any conditions.

What are SD-WAN and SD-WAN as a Service in Plain Language

For most business leaders, SD-WAN as a Service is another buzzword that doesn't speak to them. Meanwhile, this technology is vital for enterprises striving to align connectivity across branches in different countries.

SD-WAN, or a software-defined wide area network, is a solution capable of using various links starting from multiprotocol label switching and ending with virtual private networks to track and manage enterprise networks regardless of distances. Its core task is to track and measure the performance of WAN connections and data transfer processes to provide high-speed and optimized routes.

Consequently, SD-WAN as a Service is a new cloud-based generation of a legacy SD-WAN. The great business migration to the cloud led to the demand to use cloud computing methods, like SaaS or IaaS, to manage data traffic properly. So, the service has main features and benefits that are usual for other cloud solutions, such as:

  • the "rent" method of usage

  • vendor-side hosting & maintenance

  • reduced total cost of ownership (TCO)

  • lightning-fast deployment

  • no supplement equipment required

Exactly SD-WAN as a Service helped enterprises remain flexible during the pandemic when remote cooperation was necessary. Now, remote and hybrid work is here to stay. Following the UK Office of National Statistics, the proportion of hybrid workers has risen from 13% in early February 2022 to 24% in May 2022. So, in such conditions, the technology allows managers to support a high level of employee engagement, providing specialists with the ability to choose a convenient work mode.

Therefore, you can find enterprises from different domains among its core users. The only thing unifying them is affiliates in various locations and the desire to remain on the same page with each team member.
