SD-WAN vs VPN for Branch Office Connectivity
VPN and SD-WAN are not two names for the same solution. A VPN creates a secure channel between points; SD-WAN adds policies and traffic management over one or more links. The choice depends on the scenario.
When a VPN might be sufficient
For a few branch offices, predictable traffic, and a simple architecture, a well-configured VPN can provide connectivity. Considerations include the equipment terminating the tunnel, bandwidth, and who supervises the network.
What SD-WAN offers
SD-WAN allows for applying policies per application, combining links, and centralising visibility. This capability is useful in distributed networks but requires design, licensing, and operation commensurate with the expected benefits.
Deciding based on applications
Telephony, cloud applications, ERP, and server access do not tolerate latency or outages equally. Mapping traffic flows and priorities allows for comparing options without assuming that the most advanced technology is always the right fit.
