High availability and fault tolerance
- [Instructor] We've already discussed some of the ways that security professionals can ensure the continued operation of systems. Let's dig into this in a little more detail. There are two key technical concepts that improve the availability of systems. High availability, otherwise known as HA, uses multiple systems to protect against failures. HA techniques are like the ones we discussed in the previous video. Having a cluster of web servers in place that can continue to operate, even if a single server fails, is one example. 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 sites. The geographic dispersal of placing systems in different locations protects you against damage to a facility. Fault tolerance, or FT, helps protect a single system from failing in the first place by making it…
