SD-WAN 1.0: Hungry for bandwidth
The first stage of SD-WAN evolution was focused on solving the issues of availability and last-mile bandwidth. New MPLS links are expensive and slow to provision, and the use of an Internet backup meant that the backup was only used in the case of an outage. Using link-bonding, an SD-WAN predecessor could combine multiple different types of connections at the link level, improving last-mile bandwidth.
SD-WAN 2.0: The rise of SD-WAN startups
The limitation of link bonding is that it only improved last-mile performance. Achieving improved performance throughout the WAN required routing awareness throughout the path. Early SD-WAN solutions offered virtualization failover/failback and application-aware routing. With application-aware routing, SD-WAN could move away from being fully reliant on MPLS links and optimally route traffic based upon the application type.
SD-WAN 3.0: Reaching out
The latest stage of SD-WAN evolution focuses on going beyond networking branch locations. As organizations increasingly move resources to the cloud, SD-WAN provides a solution for securely connecting these cloud deployments to the enterprise WAN.
