DSR Microservices (Day 2)
The document discusses Netflix's microservices architecture and principles. Netflix uses over 500 microservices running on AWS, with 100s-1000s of daily deployments. They use services like Apache Cassandra as their scalable NoSQL database and NGINX as a load balancer. The document also discusses how other companies like Gilt and HERE migrated to microservices architectures, with Gilt moving from Ruby on Rails to Scala/Play/Docker and HERE using technologies like MQTT, Kafka, and Docker for their "Internet of Ducks".
