In computer networks, failover support is a method for protecting availability of a computer resource. For failover support to work, a component must have a redundant or alternate and there must be an ability to detect the failure of the primary component and switch to the alternate. As an example, a company web site may be hosted at one location but have an alternate hosted at a different location. If the primary site goes down, traffic directed to the primary site is redirected to the alternate site in a manner that is transparent to the outside user.

The Majority Node Set Cluster Network as a Failover cluster model does not use a witness disk.
. Failover Cluster protects the instance, while DB Mirroring protects one or more DBs. 2. failover clustering required dedicated H/W, while DB Mirroring is not required dedicated h/w
An automatic DNS Failover Service is used for to send traffic to a secondary IP address if one's main connection is not working. The DNS Failover Service regularly checks to make sure the main connection is working and if it finds a problem it diverts the traffic.
Log shipping is one of the failover solutions offered by SQL Server 2000. In this context, failovermeans substituting primary server with a backup (sometimes also referred to as standby) server if the primary hardware becomes unusable. Failover solutions can also be used to provide close to 100% uptime-during primary database or server maintenance and during software upgrades you could use the standby server to continue serving your customers. Failover solutions can be automatic or manual. With automatic failover, the backup server detects when the primary server is not available and takes over without any intervention from the database administrator. An example of an automatic failover solution is clustering. With manual failover, the database administrator (DBA) has to perform some steps to bring the standby server online. In SQL Server 2000, log shipping is a form of manual failover.
WAN Failover needs to have tests set up for each WAN Interface. These are usually run by qualified computer technicians to avoid glitches in your network.
Failover is the automatic switching of computer servers or systems from a main system to a standby system due to some kind of failure or abnormal termination that occurs within the main system.
A failover cluster.

The failover cluster is a term used in Computer Science. It represents a large amount of servers put into one place (clustered) to handle a very high load of incoming connections and continue their operation.
The term load balance is used to describe a computer networking method in which workloads are distributed across multiple computers. It is used to implement failover, which is the continuation of a service after the failure of one or more components.
