摘 要：Cloud service providers negotiate with customers to set a minimum of 99.9 percent as theguaranteed service availability level, but the range that falls in the guaranteed service levelscomplicates management of service level agreements because partner relationships can befull of complex variables. One of those variables is accumulative errors from rounding andtruncation in the calculations. The author presents a solution to this set of problems: Usenumerical analysis of performance data to obtain approximate solutions while you maintainreasonable bounds on errors as part of an SLA standardization effort.
