High-availability systems use multiple servers to protect against the failure of a single component. This includes the use of clustering and failover/standby devices. Fault tolerance helps protect a system from failing by making it resilient to technical failures. In this video, learn the basics of both high availabiity and fault tolerance.
- [Narrator] 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.…These are techniques like the ones…we discussed in the previous video.…Having a cluster of web serves 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 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,…
