This document discusses the differences between a big engineer at an established company and a small entrepreneur starting their own company. It describes the challenges a small startup faces in mobile service development including unpredictable traffic, lack of resources, and difficulty building their own cultures. The entrepreneur considers using clouds but has concerns about latency, reliability and costs. They decide to build their own hybrid system to meet goals of low latency, high performance, reliability and scalability at a low price.
