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
22 Presentation by Nick Barcet

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
