The document discusses Ubuntu Cloud Infrastructure and OpenStack deployment using Juju and Orchestra. It provides an overview of Juju for orchestrating services and deploying charms. It then demonstrates how to deploy OpenStack on bare metal servers managed by Orchestra using Juju relations to connect the OpenStack components like Nova, Glance, RabbitMQ etc. Scaling is shown to be easily done with Juju by adding additional units.

4. Ubuntu Cloud Infrastructure
Outstanding technology
Ability to use the same Ubuntu machine
images and management tools across both
private and public IaaS systems, minimising
costly re-training or application change when
moving from private to public and vice versa.

Devops Distilled
19 Presentation by Nick Barcet

20. What is DevOps?
●
Rate of agile development and deployment requires deeper
interaction between teams
●
A melding of development, deployment, and QA principles,
methods, and practices
●
Fills the gap between developers and system administrators
20 Presentation by Nick Barcet

21. What drives DevOps?
●
Speed of the deployment
●
Continuous Integration, Automated Testing, etc.
●
Fast change vs. Stability
21 Presentation by Nick Barcet

22. What does DevOps “deliver”?
●
Fast repeatable server setup, consistent environment
●
Abstract ops tasks to empower devs
●
Smaller deployments empower ops
●
Repeatable processes that let you scale out quickly

27. Juju's Charms
●
Charms are a shareable, re-usable, and repeatable
expressions of DevOps best practices.
●
You can use them unmodified, or easily change and connect
them to fit your needs.
●
Deploying a formula is similar to installing a package on
Ubuntu: ask for it and it’s there, remove it and it’s completely
gone.
27 Presentation by Nick Barcet

28. Juju is a community of DevOps expertise.
●
Most of the application you want will be available in Juju.
●
Juju provides direct and free access to a DevOps community-
contributed collection of formulas
28 Presentation by Nick Barcet

29. Juju provides service orchestration
●
Juju focuses on managing the service units you need to
deliver a single solution, above simply configuring the
machines or cloud instances needed to run them.
●
Charms developed, tested, and deployed on your own
hardware will operate the same in an EC2 API compatible
cloud, including OpenStack.
29 Presentation by Nick Barcet

30. Juju is intelligent
●
Juju exposes re-usable service units and well-defined
interfaces that allow you to quickly and organically adjust and
scale solutions without repeating yourself.
30 Presentation by Nick Barcet

31. Juju is Easy
●
There’s no need to learn a domain specific language (DSL) to
use Juju or create formulas. You can be up and running with
your own formula in minutes
