A digital-first enterprise needs SD-WAN


Since the advent of the internet and IP, networking technology has not seen a seismic shift of this magnitude that is occurring in Enterprise networks today. As organizations move from on-premises application hosting to a cloud-based approach, they are inundated with the inherent challenges of legacy network solutions. The conventional network architectures in most of today’s enterprises, were not built to handle the workloads of a cloud-first organization. Moreover, the increasing usage of broadband to connect to multi-cloud-based applications have escalated concerns around application performance, agility, and network security.

Software-defined WAN (SD-WAN) has gained immense traction among CIOs lately. Gartner forecasts that SD-WAN will grow at a 59% compound annual growth rate through 2021 to become a $1.3 billion market. This is because there are a myriad of payoffs of moving to SD-WAN: Primarily, SD-WAN enables easier access to cloud and SaaS based applications for geographically distributed branch offices and mobile work force. Here are but just a few other important benefits that SD-WAN brings to digital-first organizations:

Enhanced application experience

As organizations expand their cloud and SaaS portfolio, branch locations and remote workers increasingly depend on the internet as the preferred path to cloud-based applications. However, the public internet is a congested and latency-riddled highway. The internet, by itself, is unable to prioritize network traffic, meaning non-work-related internet usage could be consuming the bandwidth necessary for mission critical applications like web-based ERP/CRM or salesforce services.

SD-WAN couples the principals of application-aware or context-based routing to optimally leverage multiple methods of connecting remote sites to public, private, or hybrid cloud. SD-WAN allows organizations to define business intent and outcome associated with each application (prioritize business-critical applications and choose the best path for it) and determine the most optimal combination of individual users, applications, and connectivity types for intelligent network traffic routing.
