In this talk, Leo Liang, engineering manager at Cruise Automation, spoke about how OfferUp (his previous employer) evolved a high growth startup architecture into the microservice world through practical architecture examples. Over the past 2.5 years, Leo and his team worked with the Linkered community, leveraged with Consul, Nginx, Prometheus, and deeply customized Linkerd with Plugins to build up the service mesh. While at OfferUp his team scaled to billions of requests per day with ever improving system reliability and flexibility.
