Open Container Initiative. •  Under Linux foundation •  Established in June 2015 •  Currently 2 Specs

Ø  Run time Ø  Image

•  CF uses OCI runC as core container runtime

•  Interoperability & Portability

24

•  The Open Service Broker API project allows developers, ISVs and SaaS vendors a single, simple and elegant way to deliver services to applications running within cloud native offerings including Cloud Foundry, Openshift and Kubernetes.

•  Influenced by Cloud Foundry’s Service Broker API concept

•  Launched in Dec 2016 this project is joined by people from Fujitsu, Google, IBM, Pivotal , Redhat and SAP

25

Project Kubo •  BOSH-Powered, Web-Scale Release Engineering for Kubernetes. •  Joint project between Google and Pivotal. •  Announced by Google in Google Next 2017 •  Problem Kubo Solves – Uniform way to instantiate, deploy and

manage Kubernetes clusters in HA mode on any cloud •  Help for ‘Day 2’ Operations

•  Self healing VMs & Monitoring via BOSH •  Elastic scaling of clusters* •  Rolling upgrades to latest Kubernetes core* •  High Availability & Multi AZ support.

•  https://youtu.be/h9FSqVbdHis?t=52m13s •  http://pivotal.io/kubo

* Added post GCP Next through community collaboration
