OpenStack is the prevailing open source cloud software. It includes numerous API services for programmatic management of all sorts of IaaS and SaaS services. VMs, Containers, Bare Metal, Multi-tenancy. Use this platform to strike the right balance between developer self-service to your infrastructure and a well defined platform for next generation containerized microservice applications that your IT department feels happy to support and your CFO would be happy to pay for.

01: CLOUD
Pay a service provider, run your workloads there.

5. PRIVATE CLOUD
02: CLOUD
You own it, so you make the rules.

6. PUBLIC + PRIVATE CLOUD
03: HYBRID CLOUD
Decide what to run where, and have a consistent way to use both.

Consistent deployment to deploy your apps to a different destinations.

34. OPENSTACK MAGNUM
How OpenStack can host your microservice applications
34

35. What is Magnum?
• Magnum is an OpenStack API that allows the use of your keystone credentials.
• Magnum is designed from the ground-up to be multi-tenant in both the cloud’s data
plane and control plane.
• Magnum allows for different container cluster types to be simultaneously run side-
by-side in the same cloud account, by the same tenant.
• Clusters are isolated from each other using groups of nova instances.
• When you want to upgrade your container runtime, you simply create a new cluster.
HOW IS THIS DIFFERENT THAN JUST RUNNING KUBERNETES OR DOCKER SWARM?
An OpenStack API Service that allows creation of container clusters

36. Terminology (1/4)
COE
Container Orchestration Engine.
Examples: Docker Swarm, Kubernetes, Apache Mesos.

37. Terminology (2/4)
Magnum Cluster
A Magnum cluster is an API resource in OpenStack Magnum that is composed of
nova instances, neutron networks, security groups, and other resources combined
using a heat stack. This is where your Container Orchestration Engine (COE) runs.
Clusters may be scaled up or down by adding or removing nodes from them. Heat
facilitates the setup and scaling of Clusters.

38. Terminology (3/4)
ClusterTemplate
A ClusterTemplate is a model used for creating a Cluster resource. It contains
information that is common among all clusters that are instantiated from it. Each
one uses a driver that defines a cluster type (swarm, kubernetes, mesos, etc.).

39. Terminology (4/4)
Native Client
The client distributed with the COE. For example “docker” or “kubectl”. A native
client is not an OpenStack Client. It uses TLS to authenticate with the COE.

Choice. Avoid locking into a single container orchestration tool
Speed. Easily create new container clusters in ~2 minutes
Agility. Iterate quickly on your software, and make small lifts.
