SD-WAN, or Software-Defined Wide Area Network, is a technology that enables organizations to create dynamic mesh networks. It allows for the use of multiple connections, such as MPLS, broadband, and cellular, to provide direct internet access to cloud-based applications and remote locations. This approach helps organizations manage the complexity of modern IT environments, which are increasingly distributed across private data centers, public clouds, and edge locations.

Managed SD-WAN services offer several advantages, including improved operational efficiency and performance. Organizations can leverage the expertise of managed service providers (MSPs) to handle lifecycle management tasks, ensuring peak performance and cost optimization. Additionally, MSPs provide actionable insights through cloud-based management solutions, enhance security, and offer predictable pricing models, allowing organizations to focus on strategic initiatives rather than day-to-day network management.

Recent research indicates that SD-WAN is becoming increasingly ubiquitous, with 99% of surveyed organizations either using, planning to use, or expressing interest in SD-WAN technology. Specifically, 26% of respondents reported extensive use of SD-WAN, while 40% indicated limited use. This trend reflects the growing recognition of SD-WAN's ability to address the complexities of distributed environments and enhance network performance.
