Gentle introduction to Azure ARM templates and other deployment options, both imperative and declarative, such as Terraform, Ansible, or even azcli or PowerShell.

2. What is DevOps

4. http://www.itproguy.com/devops-practices

5. Infrastructure as Code

6. “Infrastructure as code is the approach to
defining computing and network
infrastructure through source code that can
then be treated just like any software
system.”
Martin Fowler

7. Azure Resource Manager

10. A service that supplies the resources you can
deploy and manage through Resource Manager.
Each resource provider offers operations for
working with the resources that are deployed.

11. Resource Providers from PowerShell

12. a Resource Provider
might be registered
to your subscription

13. Imperative

Declarative

15. Example: creating a Storage Account

19. One more (imperative) example:

20. How to develop an ARM template
Visual Studio Code Visual Studio Azure Portal

23. Quickstarts
templates
on GitHub

24. Visualize ARM
templates on
armviz.io

25. How to test an ARM template

https://blogs.technet.microsoft.com/stefan_stranger/2017/08/02/testing-
azure-resource-manager-template-functions/
Some more examples:

26. template1a.json
template1b.json
template1c.json
template1.json
A template can reference
other templates

27. template1.json
You can split a template into different
(cross-dependent) templates
template1a.json template1b.json
= +

28. Simplified json
with Azure
building blocks

This example does the following:
• Deploys 3 VMs in an Availability Set
• Enables diagnostics
• Uses managed OS Disks
• Uses Windows Server 2016
• Creates Public IP for each VM

30. Configuration Management

Get the first usable IP in the
subnet (i.e. 10.25.60.36)

40. •User defined functions in templates
•Subscription based deployments
 Deploy subscription-level resources
 Role definitions
 Role assignments
•Rollback
 To previous deployment on fail

Make Azure a first class provider in Terraform
• Increased Azure resource coverage
• More TF Azure modules
