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.

Introduction to SRE
This module is intended to bring you up to speed on the concepts underpinning SRE, CRE, and SLOs. If you're already familiar with these concepts, you may still find new information and perspectives in this module, but it is not necessary to complete it.

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.

Quantifying Risks to SLOs
In this module we'll be taking a critical look at the availability risks for our example service. We want to answer the question: "are our SLO targets and error budgets realistic?"

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.

por DS27 de Set de 2020
Excellent course on SRE principles. Peer reviews are awkward due to lack of metric information, but they content attempts to re-enforce the principles and provide practical experience to the learner
por EY21 de Abr de 2020
The course itself was great. It was a bit upsetting to see that many of the assignments submitted by our peers are mostly copy and paste from the lectures or direct copies from the examples...
por PM22 de Jun de 2020
SRE is not 100% technical course like other cloud services ( VM Instances, Storage , Compute ...etc) . It is very well designed and explained . Very very interactive and thought provoking
por MS2 de Mai de 2020
It's really a very useful course related to SRE, especially how defining SLIs and SLO targets. The approach to analyzing risks based on SLOs is also a very good practice to be adopted.
