I read SLO Service Level Objectives: A Practical Guide to Implementing SLI, SLO, and Error Budgets.

• The book discusses the definition of services and users.
• When considering SLOs, I thought it was particularly important to enhance the resolution regarding users.
  • If the resolution is low, there is a tendency to excessively enhance the reliability of the service or end up with meaningless metrics.
• Whether a service is reliable is equivalent to whether the service performs the actions required by the user.
• SLOs are goals and are subject to change. Discussions for change are valuable.
• SLOs are not just simple metrics for improving reliability; they provide insights for development and operational improvements by collecting data based on these metrics.
• Error budgets are challenging to operate, but if implemented, they can provide data and opportunities for discussion to improve teams, organizations, companies, and services.
• To introduce SLOs into an organization, you need the consent of superiors, expectation adjustments, explanations of time investment effects, and the resolve to take on a cross-functional role.
