PUBLIC CLOUD SERVICE

01: CLOUDPay a service provider, run your workloads there.

PRIVATE CLOUD

02: CLOUDYou own it, so you make the rules.

PUBLIC + PRIVATE CLOUD

03: HYBRID CLOUD

Decide what to run where, and have a consistent way to use both.

Use the r ight tool for the job

Containers

Consistent deployment to deploy your apps to a different destinations.

WHY? BECAUSE SHADOW IT.

DEVELOPER SELF SERVICE

If you don’t offer it as a service, it’s going to happen anyway.

MICROSERVICE ARCHITECTURE

NEXTGEN APPLICATIONS

Immutable infrastructure, Container per component, 12-Factor apps

YOU KNOW YOU WANT IT(subliminal message)

WHY?

MICROSERVICES

Continuous deployment, efficient scale, smaller lifts to upgrade. Agility.

OPENSTACK MAGNUMHow OpenStack can host your microservice applications

34

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

Terminology (1/4)

COE

Container Orchestration Engine. Examples: Docker Swarm, Kubernetes, Apache Mesos.

36

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.

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.).

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.

•You may need a private cloud just as much as you need a public one. •Shadow IT will happen if you don’t offer a developer self service option •Microservice software architecture for efficiency and agility reasons •Software defined economy means agility is essential to avoid disruption

•One cloud == Myth. •Use containers as a way to deploy apps to the cloud of your choice.

•OpenStack: prevailing open source cloud software •Offers compute, networking, and storage (+715 modules for everything under the sun). •Safe to bet on OpenStack because of diverse community & no single corporate sponsor. •Offers quick and easy way to run different container orchestration environments.

•Many ways to deploy and run OpenStack •OpenStack Ansible Recommended
