Open Cloud Day 2017 - Cloud Native Computing

Introduction into Cloud Native Computing and the Cloud Native Computing Foundation at Open Cloud Day 2017 in Bern by ch-open.

While Cloud has been used synonymously with outsourcing and Open Source with "free software tools", Cloud Native Computing has established itself as a set of established best practice patterns for building distributed software applications with a community, a successful track record, a set of Open Source tools and a nonprofit foundation hosted by The Linux Foundation to support them. These best practices and tools can and should be used when developing new software - no matter if it will be run in the cloud or not - to leverage the advancements in distributed software development. In this talk I'll present the Cloud Nativev Computing Foundation and explain the business impact of some of its best known Open Source projects: Kubernetes, Fluentd and Prometheus.

12. VSHN AG I Neugasse 10 I 8005 Zürich I T 044 545 53 00 www.vshn.ch Why Cloud Native Computing? • Patterns: higher level problem solving than 'just use tool x' • Open Source and Open Standards • Broad support consortium • Runs on any infrastructure cloud native → not cloud only • Application Infrastructure as Code • DevOps Philosophy
