We implemented and currently support some clients using Cisco SD-WAN.
Essentially, everything is moving to the cloud. There is a big shift from the traditional network operator-based infrastructure to a fully cloud-native kind of infrastructure for companies. People don't want to deal with so many providers. The network provider, the cybersecurity provider, another company managing the routers and firewalls, et cetera. Everything is moving to the cloud to simplify things. The shift to SD-WAN is motivated by business reasons. It allows for cutting costs. Traditional networking forms for data centers are simply too expensive, too slow, and very time-consuming to maintain.
Today with the SASE architecture, it's very easy to immediately deploy the cloud to have one subscription for one set of services. With one subscription, you have full access to a dedicated network that is much faster than the traditional MNTL networks that traditional data centers are using. Plus, you have integrated cybersecurity and a fully dedicated private backbone that is essentially spreading across the globe. People don't want to delegate to British telecom off to Verizon anymore, handing their network into another company managing the security into another company managing the networking infrastructure. With SD-WAN, especially with solutions based on the SASE framework, they pay one subscription fee each month, and one single company is managing everything.
