Software-defined WAN (SD-WAN) adoption has been driven by a need for greater agility, reliability and performance. Legacy WAN architectures are complex, expensive, and difficult to provision, maintain and support. SD-WAN creates a more intelligent network that reduces telecom costs and simplifies remote connectivity.
Communication and collaboration tools have been a lifeline for employees working from home. Voice and video conferencing, chat and instant messaging, presence, and document sharing have enabled remote workers to stay in contact with colleagues and streamline workflows.
