Another is using a pair of firewalls…with one designated as the backup.…The core concept of high availability…is having operationally redundant systems,…sometimes at different locations.…Fault tolerance, or FT, helps protect…a single system from failing in the first place…by making it resilient in the face of technical failures.…One quick note, load balancing is a related…but different concept.…Load balancing uses multiple systems…in an attempt to spread the burden…of providing a service across those systems,…
