Overview

In this exercise, you follow the process used on the User Profile journey to develop Service Level Indicators (SLIs) and Service Level Objectives (SLOs) for the Buy In-Game Currency journey.

Objectives

In this lab, you learn how to perform the following tasks:

  • Study the Buy In-Game Currency user journey.
  • Design a set of SLIs and SLOs.

Getting ready

If you are attending an in-person, instructor-led event, please take a moment to form into teams of approximately 4 people. If you are attending virtually, please do the exercise on your own.

Task 1. Study the Buy In-Game Currency user journey

  • Take a moment and review the Buy In-Game Currency user journey.

Buy In-Game Currency

Our most important user journey is the one that generates all our revenue: users buying in-game currency via in-app purchases. Requests to the Play Store are only visible from the client. We see between 0.1 and 1 completed purchase every second; this spikes to 10 purchases per second after the release of a new area as players try to meet its requirements.

Task 2. Design a set of SLIs and SLOs

Remember the SLI equation:

SLI equals open bracket good events divided by valid events closed bracket, multiplied by 100 percent

  1. Have someone on your team create a copy of the following file and share it with the rest of the team: SLO Worksheet.

  2. As a team, use the worksheet and plan at least one SLI/SLO. Feel free to do more if you have the time. Be prepared to present your ideas to the class.

Note: Accessing the SLO doc using the student lab account won't work. Use a standard browser window, not the incognito window, to access the doc.

Review

Congratulations!

You successfully planned SLIs and SLOs.
