The document discusses the Cloud Native Computing Foundation (CNCF) and provides an overview of cloud native concepts. It describes the CNCF's mission to foster open source, vendor-neutral cloud native projects and some of its activities. It then outlines a scale from houses to cities to describe how cloud native practices become more important as software systems increase in complexity and size, from source control and continuous integration for small systems, to high availability, storage and security for large systems with 500+ services. The document promotes upcoming KubeCon + CloudNativeCon conferences in Europe, China and North America.
