Get to know how Terraform can be used to help build and manage the change of the infrastructure to support your serverless solutions on Azure.

3. Agenda
• Terraform 101
• Demos
• 101
• Local Development
• Build
• Deploy

4. What is
Terraform
Developed in 2014 by Hashicorp
(http://Terraform.io)
Infrastructure as configuration
Build change and version control
infrastructure
Talk to multiple cloud and infrastructure
providers

5. Features/Process
Apply incremental changes as you develop
solution
Test and preview your infrastructure changes
Destroy and rebuild as required
Abstract the vendor API from your definition
State file manages the state of your changes

6. Terraform File
Structure

7. Typical Serverless Solution

8. Why do I care for Azure Serverless Solutions
ARM deployments are a Pain
Often lots of Azure Resources to setup
Abstracts complexity
Deploy deltas rather than remove and replace
Consistent & repeatable deployment of resources

9. Simple Demo Terraform

10. Development Locally on developer
machine

11. Local Development Machine
Azure Resource Group
For DEV Environment
Local Process
Visual Studio Deployment
Setup Solution Infrastructure

12. Build Pipeline Azure DevOps

18. What kind of solutions can I build?

19. Workarounds
& Pain Points
• Azure DevOps Tasks – Does it work properly?
•  Local - Remote State works but do I need it?
•  DevOps – OOTB Tasks = Remote state
doesn’t seem to work properly
•  Upload / Download State file
• Terraform
• Local – Az Login interactive
• DevOps – Set the client principal to pipeline
variables

20. Resources that arent supported??

21. Thoughts
• Terraform isn’t perfect but is maturing
• It simplifies a lot of things once you get it all up and
running
• Find balance between using Terraform vs other
approaches
• EG: SQL Scripts or Function Deploy
• How do I slice and dice my builds/releases
