High Availability Lens 3

1 Comments

In previous high availability lens 2, we saw general formula to express availability in terms of uptime and downtime. And also in terms of MTBF and MTTR.

MTTR is mean time to repair ,i.e. average time required to repair a failure. If we look at the formula for availability in terms of MTBF and MTTR, we can observe that we can make very interesting conclusion. As MTTR tends to zero, availability tends to 1 ,i.e. 100%

And this is where clustering softwares come into picture by helping MTTR reduce by automation. It should be also noted that MTTR is affected by lot of complexities such as application dependencies, underlying hardware being used etc.
