ATC-SREA - SRE for Architects

Overview

Duration: 3.0 days

Site Reliability Engineering (SRE) is a set of principles and practices that supports software delivery - keeping production systems stable and still delivering new features at speed. In this course, Site Reliability Engineering (SRE): The Big Picture, you'll get a thorough overview of how SRE works and why it's a good choice for many organizations. First, you'll learn the differences between SRE, DevOps, and traditional operations. Next, you'll discover how engineering practices help to reduce toil and provide more time to focus on high-value tasks. Finally, you'll learn how SRE approaches monitoring and alerting, and about the SRE approach to managing incidents. When you're finished with this course, you'll be able to evaluate SRE and see if it's a good fit for your organization.
