  Introduction to Amazon Style Microservices If you’ve ever wondered how Amazon manages millions of transactions, delivers personalized recommendations, and ensures near-perfect uptime, the answer lies in microservices . Instead of running on a single, massive application, Amazon’s platform relies on thousands of small, independent services working together seamlessly. Microservices are like tiny puzzle pieces.
