What this capability actually buys you
Business continuity when a carrier fails. Critical traffic — payments, voice, safety systems — prioritised and steered onto the healthiest path. Sites connected over whatever mix of services each location can get, managed as one network with one policy.
Where it fits
Multi-site operations where a site outage is a business outage. Single sites whose Internet dependence has quietly become total. Remote and regional locations combining imperfect connections into one dependable service.
Where it doesn’t
A site that can tolerate a day offline does not need this. We will say so — resilience is sized to consequence, and the honest answer is sometimes a simple backup connection or none at all.
