Digital transformation initiatives, and associated WAN
transformation, introduce both challenges and new opportunities.
The cloud, big data, social, mobile, and even IoT play a central role in this transformation, and it is critical that enterprises get the WAN architecture right.
Unfortunately, traditional WAN options are either not flexible, are expensive, and are just incapable of handle the demands of a modern digital enterprise.
Direct cloud connectivity, application acceleration, end-to-end security and global SLAs are features that are either not available or available with the addition of expensive new hardware.
The network transformation journey is not an easy one, given the critical nature of connectivity and the consequences of a network outage. Unlike the static enterprise WAN of yesteryears, the enterprise WAN networks of today are living, breathing, dynamic entity; that need to continually evolve with the needs of the business. In such an environment, not only the choice of technology (SD-WAN) but also the mode of operation matters.
In such a fast-changing dynamic environment, the DIY approach (do-it-yourself) to SD-WAN has many challenges, such as the need for expensive resources as well as purchasing contracts with OEMs. Carrier provided SD-WAN may be an option, but it comes with conditions attached, like last and first-mile lock-in, long rollout times, no single SLA and multiple contracts for end-to-end connectivity.
