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.
