If we start with the need to make the business more agile and responsive to opportunities and competitive threats, a big component of the time taken is in the development and delivery of web services. Cloud Native architecture delivers speed, scalability and security through automation of continuously delivered single function micro-services with a denormalized NoSQL back end. In the case of Netflix, the streaming service is deployed globally using Cassandra to provide cross zone and cross regional replication. NetflixOSS is a set of open source components that anyone can use to help them adopt Cloud Native architectures, and there is even a prize for the best open source contributions to NetflixOSS at http://netflix.github.com
