  1. Availability

    In reliability theory and reliability engineering, the term availability has the following meanings: ⁕The degree to which a system, subsystem or equipment is in a specified operable and committable state at the start of a mission, when the mission is called for at an unknown, i.e. a random, time. Simply put, availability is the proportion of time a system is in a functioning condition. This is often described as a mission capable rate. Mathematically, this is expressed as 1 minus unavailability. ⁕The ratio of the total time a functional unit is capable of being used during a given interval to the length of the interval. For example, a unit that is capable of being used 100 hours per week would have an availability of 100/168. However, typical availability values are specified in decimal. In high availability applications, a metric known as nines, corresponding to the number of nines following the decimal point, is used. In this system, "five nines" equals 0.99999 availability.
