SRE Classroom: Learning about NALSD and SRE
Introduction
SRE Classroom is a collection of workshops developed by Google's Site Reliability Engineering group. The goals of this workshop are to (1) introduce participants to the principles of non-abstract large systems design (NALSD), and (2) provide hands-on experiences with applying these principles to the design and evaluation of these systems. We consider NALSD a concept fundamental to SRE, and understanding its principles provides a basis for having meaningful conversations about the design and operation of large software systems.
Tutorials
Distributed PubSub
Build a planet scale distributed PubSub system using NALSD principles. Learn about some foundational large system design principles and concepts. Topics include correctness, reliability, performance, different inter-system communication styles, and more. We introduce the problem requirements in detail and walk through an example solution.
Distributed ImageServer
Build a planet scale distributed ImageServer system using NALSD principles. Learn about some foundational large system design principles and concepts. Topics include sharding, replication, latency, load balancing, and more. We introduce the problem requirements in detail and walk through an example solution.
The Art of SLOs
The Art of SLOs introduces participants to concepts in measuring service reliability: Service Level Indicators (SLIs) and Service Level Objectives (SLOs), and gives them some hands-on experience with creating these measures in practice.
