When engineering organizations adopt microservice architecture, and split their large monolithic applications into hundreds (or thousands) of microservices, one of the biggest challenges they face is the lack of architectural and organizational standardization across their microservice ecosystems. In this report, author Susan Fowler looks at lessons learned from driving a production-readiness initiative across Uber’s more than one thousand microservices. You’ll explore eight production-readiness requirements that she and her fellow SREs at Uber adopted after countless hours of research inside and outside the company—requirements that apply to every microservice while providing real, quantifiable results: stability, reliability, scalability, fault-tolerance, catastrophe-preparedness, performance, monitoring, and documentation.
