This session illustrates how devops can use Heat to orchestrate the deployment and scaling of complex applications on top of OpenStack. Starting with a walk-thru of the example deployment Heat Templates for OpenShift Origin (available in openstack github repository) I’ll walk thru the existing templates and enhance them to provide additional functionalities such as positioning alarms, responding to alarms, adding instances, and auto-scaling.

6. Infrastructure is not enough

l Network, storage &
compute as an on-
demand service
l Basically, servers in
the cloud
l You’re still on the
hook to configure &
manage the cloud &
stack
“How do I use this?”
Infrastructure as a Service gives you

l Application runtime
environments in the
cloud
l Configures and
manages both the
cloud & the stack for
your application
“Now the cloud is useful!”
Platform as a Service delivers

9. PaaS = Platform as a Service
A Cloud Application Platform

57. Heat's mission: Orchestration
To explicitly model the relationships between
OpenStack resources of all kinds; and to
harness those models, expressed in forms
accessible to both humans and machines, to
manage infrastructure resources throughout
the life-cycle of applications.

64. Best practices for
using PaaS on IaaS

65. 27
Configure OpenShift to meet your needs
l All-in-one deployments
- Single host (broker+console+node)
l Configuring separate hosts for broker/node
l Highly-available OpenShift deployments
l Capacity planning districts
- http://openshift.github.io/documentation/
oo_administration_guide.html#capacity-planning-and-
districts
l VMs for easy developer desktop deployments
- http://openshift.github.io

PaaS on IaaS best practices
1
Consider future of PaaS and
OpenStack
2
Plan for today and future needs
3
Leverage and build on existing
skill sets and investments
