5 Reasons SD-WAN, 4G LTE Are Cloud Essentials

Originally published September 7, 2017

Businesses of all sizes across many industries are embracing cloud-based IT solutions in lieu of traditional on-premises server deployments, but wide-area network (WAN) implications brought about by this transition aren't immediately recognized.

Cloud-based applications for office automation, Web and video conferencing, file sharing, VoIP and collaboration -- including Microsoft 365, Cisco Spark, Slack, Box, and others -- are proliferating due to the reduced cost and complexity associated with rolling out and managing these services across a distributed enterprise.
