Talking Points• Review some common cloud decisions and day-to-day operator tasks• Learn why OpenStack and automation work great together• Review some automation considerations before getting started• Step thru how to automate various tasks with OpenStack• Benefits of adopting an ‘Administration DevOps’ state of mind and
next steps

So you have a cloud, now what?
Why not create some roles and playbooks to automate all those pre-configurations

Decisions, decisions…

OpenStack AutomationAPIs and/or

Hypervisor
7@ d j s t a y fl y p r o
Before you get started…
A few possible automation considerations:
• Create a plan with goals, objectives and planned outcomes• Make framework decisions ahead of time; then stick to them• Code consistency
Defining environment variables
API vs. CLI Where to run the codeShould the automation code run locally on the control plane or remotely? Yes, you have to decide
Within your automation code you have to decide whether to consume the OpenStack API or CLI
Automation code should leverage variables as much as possible; variables can be defined globally or per role/recipes/manifests/modules

OpenStack Scenario #1As a cloud operator,you want to empower the QA team with the ability to stand up their own test environments… • What would be your approach for doing this with OpenStack? Provide
QA with a project and say good luck?• Is there more you could do for them? How could you make this a single
‘push button’ solution?

OpenStack Scenario #2As a cloud operator,what if you were tasked with creating 50 users and projects… • How long would it take you using Horizon? Using the CLI?• Keep in mind you have password standards to meet, given a tight
timeline and will need to avoid mistakes/typos.• What if you need to now adjust the quotas for all 50 projects next?

OpenStack Scenario #3As a cloud operator,what if you were tasked with managing two separate cloud regions in two separate datacenters… • Could you easily do this? Would you manage them as two separate
clouds or as one?• Would executing single API or CLI requests be enough?• Is there a way to have a single interface to handle them all?

‘Administration DevOps’ Concepts and Principles
17
Automate everything – do it once and run it hundreds of times
Influence application design; cloudy applications should:
easily scale horizontally be designed to consume disposable
computing resources be designed in a share nothing approach
(stateless) be built in an DevOps model be built to expect failures
