01. Consumers Vs Creators
SD-WAN is not a single-box, plug and play solution. A comprehensive SD-WAN solution requires interworking between various elements. As consumers rather than creators of the technology, carriers are limited in their ability to offer best-in-class service.
02. Inflexible Pricing
Carriers networks involve agreements between multiple service providers. As a result, their pricing model is designed to compensate every player in the value chain, thus making them inflexible and expensive.
03. Last Mile Lock-in
Carriers tend to lock customers into their last-mile solution, rather than let them choose the best available option.
04. Inconsistent SLAs
Carriers typically operate within their service area. Thus, International connectivity is achieved through agreements with multiple service providers, making it impossible to guarantee end-to-end SLAs. As a result, the service offered is with the least common denominator set of features.
05. Not Cloud Ready and Agile
Digital Enterprises operate in an environment that requires agility. Rolling out new cloud applications, ramping down or migrating from legacy applications, the opening of new branches or closing of non-performing ones all need changes to the WAN. A legacy WAN is incapable of keeping pace with rapid changes.
