JujuDevops Distilled
20 Presentation by Nick Barcet
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
21 Presentation by Nick Barcet
What drives DevOps?
● Speed of the deployment
● Continuous Integration, Automated Testing, etc.
● Fast change vs. Stability
22 Presentation by Nick Barcet
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
23 Presentation by Nick Barcet
You've got the tools already
● Hardware● Virtualization● Platform (OS) ● Configuration Management
… need to tie that together into something whole.

Juju, DevOps Distilled
● Reuse existing deployment charms in an openly-accessible repository of shared expertise
● Reproduce deployments for test and staging purposes
● Rapid deployment of your dependencies for development purposes
● Compose whole systems from individual application components and describe the entire deployment
● Explicit control over deployment, configuration and upgrade options
● See what’s deployed and track usage in the cloud
● Create and share charms for new applications
● Monitor, scale, shrink and adjust deployment parameters in real time
● Explicitly connect different components and maintain those relationships over time
● Collaborate with developers on the exact deployment and upgrade processes
● Get more done: implement decisions immediately regardless of infrastructure scale

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.
28 Presentation by Nick Barcet
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
29 Presentation by Nick Barcet
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.
30 Presentation by Nick Barcet
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.
31 Presentation by Nick Barcet
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

Juju's internals
33 Presentation by Nick Barcet OpenStack in Action, Paris
Juju
Juju treats individual services as atoms that are described as charms and can be instantiated one or many times.

Juju
Juju maintains the relations between the services so that you don't need to care about the elasticity of your environment.
Relations are to charms what bounds are to atoms.
Services are loosely coupled but highly cohesive.

37 Presentation by Nick Barcet OpenStack in Action, Paris
Juju
Juju delivers service focused management through their life-cycle
● Offers the same simple rules to components of you infra as we do already for packages on your servers: dependencies, provides
● Adds the notion of dynamic relations between components
● To provide you with simple automated elasticity that is easy to expand
● Working on your bare metal servers (through Orchestra*) as easily as on your favourite clouds (AWS, OpenStack*, ...)
