Title: OpenShift on OpenStack: da Heat ad Ansible
Duration: 45 (includes Q&A)
Q&A Session: 0
Language: it
Type: Talk

Abstract: ## Abstract

This talk presents the wonderful and challenging journey in the devop world I made deploying an  automated and self-healing  [openshift][1]-on-[openstack][2].

OpenShift is the opensource PaaS based on [kubernetes][4] and [docker][5], OpenStack is the reference implementation of an opensource cloud provider.

Topics spaces from bare-metal interactions to application planning.

The talk ends with a rationale for the migration from Heat to a mix of Heat and [Ansible][7].

### You'll learn

  - General layout of a Kubernetes/OpenShift Cluster
  - When to use an orchestration service (eg. CloudFormation/Heat) vs Ansible vs mixed approach
  - Key points of planning a docker cluster
  - some errors you wouldn't like to do ;) 

### Agenda

  - openshift-on-openstack architecture overview 
  - key points of a docker-based PaaS (quotas, emptydir, storage, ...)
  - self-healing infrastructures with [Heat][8] (pro/cons)
  - advantages of introducing Ansible as the principal orchestration tool
  - Considerations on the future architecture (Ansible -> Heat -> Ansible)
  
## Prerequisites

Familiarity with orchestration concepts, service scheduling, tiered architectures.
