Failover Testing

What is Failover Testing?

Failover testing is a testing technique that validates a system's ability to be able to allocate extra resource and to move operations to back-up systems during the server failure due to one or the other reasons. This determines if a system is capable of handling extra resource such as additional CPU or servers during critical failures or at the point the system reaches a performance threshold.

Example:

Failover testing is very much critical for the following types of applications:

• Banking Application

• Financial Application

• Telecom Application

• Trading Platforms

Factors to be Considered:

The Following factors need to be considered before considering failover testing:

• The cost to the company due to outages

• The cost of protecting the systems, which are likely to break down

• The likelihood or probability of such disaster

• The potential outage period/downtime due to disaster
