Load balancing is often used to implement failover—the continuation of service after the failure of one or more of its components. The components are monitored continually (e.g., web servers may be monitored by fetching known pages), and when one becomes unresponsive, the load balancer is informed and no longer sends traffic to it.
Round-robin DNS is a technique of load distribution, load balancing, or fault-tolerance provisioning multiple, redundant Internet Protocol service hosts, e.g., Web server, FTP servers, by managing the Domain Name System's (DNS) responses to address requests from client computers according to an appropriate statistical model.
Its primary purpose is to provide failover redundancy, especially when used with firewalls and routers. In some configurations, CARP can also provide load balancing functionality. CARP provides functionality similar to Virtual Router Redundancy Protocol (VRRP) and to Cisco Systems' Hot Standby Router Protocol (HSRP).
Adaptive load balancing (balance-alb) includes balance-tlb plus receive load balancing (rlb) for IPv4 traffic and does not require any special network switch support. The receive load balancing is achieved by ARP negotiation. The bonding driver intercepts the ARP Replies sent by the local system on their way out and overwrites the source ...
The Red Hat Cluster Suite (RHCS) includes software to create a high availability and load balancing cluster. Both can be used on the same system although this use case is unlikely. Both products, the High Availability Add-On and Load Balancer Add-On, are based on open-source community projects. Red Hat Cluster developers contribute code ...

The term "failover", although probably in use by engineers much earlier, can be found in a 1962 declassified NASA report. [2] The term "switchover" can be found in the 1950s [3] when describing '"Hot" and "Cold" Standby Systems', with the current meaning of immediate switchover to a running system (hot) and delayed switchover to a system that needs starting (cold).
(The Center Square) – A new Republican oversight report accuses former Congresswoman Liz Cheney of colluding with witnesses in the Jan. 6 Select Committee investigation that she oversaw. The ...
