We'll look at the three principles we use to measure the desired reliability of a service: figuring out what you want to promise and to whom, figuring out the metrics you care about that make your service reliability “good", and finally, deciding how much reliability is good enough....

Operating for Reliability

In this module, we’ll start by introducing a mechanism for quantifying unreliability using something called an error budget. We'll show how error budgets help you decide when to focus on making a service more reliable. And then we'll learn about some of the engineering and operational improvements that can help you do that....

Because the choice of where to measure an SLI is a key variable, we'll cover the five main ways you can measure an SLI and compare their pros and cons....
