This course teaches the theory of Service Level Objectives (SLOs), a principled way of describing and measuring the desired reliability of a service. Upon completion, learners should be able to apply these principles to develop the first SLOs for services they are familiar with in their own organizations.

Targeting Reliability
In this module we’re going to talk about how you measure the desired reliability of a service. We will address what to consider when setting SLOs for your application within your organization. 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.

Choosing a Good SLI
In this module we will start off by taking a look at some characteristics of monitoring metrics that can make them useful as SLIs and contrast these against other metrics that are less useful. 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.

Developing SLOs and SLIs
In this module, we'll start off with an overview of our four step process for developing SLOs and SLIs for a user journey. We'll introduce the fictional company that created our example mobile game, the infrastructure that we'll be working with, and the simple user journey we'll be applying the four step process to.

Consequences of SLO Misses
In this module, we'll cover best practices for documenting your SLOs, the rationale behind a formal error budget policy and how best to create one and finally, we'll look at an example error budget policy in order to understand the trade-offs and incentives that play out during negotiations when trying to write an error budget policy.

Most of the course is very nice, just a couple of quiz are not well though. Is surely a very good resource for everyone try to understand and verify their SRE knowledge.
par RASep 6, 2019
Very useful course to introduce SRE concepts. In combination with the SRE book, it's the way to go to learn and start applying SRE in your project/company.
par YYJun 5, 2019
Content is great. I mark course as 4/5 because it seems that teachers simply read text from paper and this really complicates understanding information.
par AGOct 27, 2019
SRE: Measuring and Managing Reliability is a great opportunity to learn and practice SLI, SLO, error budget policy and focus in the user happiness.
par VROct 7, 2019
Fantastic course, as an SRE I learned a lot. Very informative, short and crisp videos are a big plus. Beautifully crafted and nicely structured.
par BSNov 24, 2019
Amazing to who is trying to learn all the concepts around SRE and wants to figure out a way to start implementing them in their organization. =]
par SOOct 20, 2019
Exceptional content... challenging homework and quizzes. I learned a lot which is directly applicable to work i'm doing at my company. Thanks!
par TBApr 1, 2020
Excellent course. Videos, reading assignments, and exercises were relevant, practical, and contributed to immediate applicability on the job.
par SMMar 1, 2020
Fantastic course. Make many more in the DevOps area and make them regular to refresh the learning with new concepts that keep on changing.
par DSFeb 23, 2020
They need better instructors. Especially that bald big Asian guy. he was going super fast and was hard to follow.
par SVOct 4, 2019
An excellent course to understand the core concepts of Reliability in IT systems and apply the same practically.
par PBOct 14, 2019
The course was informative and explained the process and language around SLI SLO methodology very well.
