Question

In cloud, service uptime is 50 minutes and downtime is 10 minutes in an hour. What is the availability of the service? (a) -4 (b) 0.2 (c) 5 (d) 0.8

Answer 1

Availability (A) = 1 – (downtime/uptime)

answer=0.8

Answer 2

Answer: (d) 0.8.

                 The formula for calculating the availability of a service in information technology is:  

                      (AST-DT)/ AST where AST is Agreed Service Time and the DT is Down Time. So, the calculation would go on like:  

                 The Agreed Service Time here should be 1 hour = 60 minutes.

                 And, the down time is given = 10 minutes

So, the Availability of the service should be =

                                                            = (60-10)/50          

                                                                          = 0.83

So, The correct choice of answer for the given question from the given list of possible answers is (d) 0.8.
