The secure-access service edge (SASE) model developed by Gartner ties into SD-WAN, edge computing and SD-Branch, so it warrants attention from networking teams.
In evaluating SD-WAN, IT pros should look for better security, manageability and support for SaaS, but also check whether technology providers are likely to be acquired or perhaps close-up shop.
Integrating white-box switches into multi-vendor environments presents management and support issues.
With Wi-Fi an essential part of branch-office network access, its security and management needs to be fully baked into SD-Branch platforms.
Wi-Fi remains the most prevalent wireless technology in enterprise networks, but private 4G LTE cellular technology, and soon 5G, can be the answer in specific use cases involving remote and mobile deployments and high-capacity needs including IoT.
5G is a cellular service, and Wi-Fi 6 is a short-range wireless access technology. Each has attributes that are useful in specific enterprise roles.
SD-WAN offers cost savings, improved reliability, security and more
A wealth of standards, possible architectures and applications makes careful planning of mobile edge systems important, difficult.
Cooperation between SD-WAN vendors and cloud service providers contributes to easily managed cloud connections across multiple cloud providers and creates a secure, low-latency multi-cloud environment.
Developments in cloud services, security, containers, and white-box switches can make a positive impact for SDDNCs in the coming year.
