OpenStack is a free and open-source software platform for cloud computing , networking and stroge

Users either manage it through a web-based dashboard, through command-line tools, or through RESTfulweb services.

What is Zun ?

ZUN

Zun (ex. Higgins) is a Container Management service for OpenStack.

It aims to provide an OpenStack API for launching and managing containers backed by different container technologies.

Why is Zun ?

Zun ArchitectureZun API:

Process REST requests and validate inputted

parameters.

Zun Compute:

Launch containers and manage compute

resources in localhost.

Keystone:

Authenticate incoming requests.

Neutron:

Provide networking for containers.

Glance:

An option to store container images (another

option is DockerHub).

Kuryr:

A Docker network plugin for connecting

containers to neutron networks.

What is Magnum ?

Magnum is an OpenStack project which offers container orchestration engines for deploying and managing containers

Magnum OverView

Why is Magnum ? ● Complete multi-tenancy implementation

● Provide multiple COEs

● Provide abstract cluster

● Provide VM or Bare Metal

● Easy Scaling

● Use keystone credentials

What is Feature ?

● Kolla

● Kolla Kubernetes

● Kuryr Kubernetes

● Stackube

What is Kolla?

Kolla provides production-ready containers and deployment tools for operating OpenStack clouds that are scalable, fast, reliable, and upgradable using community best practices. KOLLA

What is Kolla-K8S ?

The kolla-kubernetes deliverable deploys OpenStack on top of Kubernetes.The Kubernetes feature makes the deployment of Openstack more flexible.

What is Kuryr-K8S?

Bridge between containers frameworks networking models to OpenStack networking abstraction.The Kuryr-K8S effort is focused to be the courier that delivers Neutron networking and services to Kubernetes.

What is Stackube?

Stackube is a Kubernetes-centric OpenStack distro. It uses Kubernetes, instead of Nova, as the compute fabric controller, to provision containers as the compute instance, along with other OpenStack services (e.g. Cinder, Neutron).

It supports multiple container runtime technologies, e.g. Docker, Hyper, and offers built-in soft / hard multi-tenancy (depending on the container runtime used).
