Site reliability engineering (SRE) is a software engineering approach to IT infrastructure and operations that aligns incentives between development and operations and includes mission-critical production support. This course starts with an introduction to the main practices of SRE and the role IT and business leaders play in the success of SRE adoption. The course then introduces participants to how Service Level Indicators (SLIs), Service Level Objectives (SLOs), and error budgets should be used to measure a service’s reliability. Attendees will gain experience with creating these measures in practice. These concepts help create a culture where the reliability and success of a service can be objectively measured.
Learning Objectives
- Articulate the technical and cultural fundamentals of Site Reliability Engineering (SRE) and understand the value they can provide to your IT operations in any environment
- Learn SRE terminology
- Understand why services need Service Level Objectives (SLOs)
- Achieve developer and operation harmony with error budgets
- Choose appropriate Service Level Indicators (SLIs) based on user journeys
- Create specific, measurable, achievable, relevant, and time-bound SLOs
- Explore techniques to reduce toil for development, testing, and operations
- Review containerization and microservice architecture
Who Should Attend
This course is aimed at development and operations engineers and technical managers, but can also be useful for product and business leaders wanting to learn more about what SRE is.
Activities
This course contains several design activities to provide real-life experience with creating these SRE measures in practice. These concepts help create a culture where the reliability and success of a service can be objectively measured.
