This document provides an overview of AWS CloudFormation, including its key components like templates, parameters, resources, and outputs. It also discusses how CloudFormation can be used to automate infrastructure deployment and management through templates, helping to ensure environments are consistently configured and deployments are reproducible. A demo of CloudFormation is promised to illustrate its capabilities.

1. CloudFormation
AWS Resource Automation

2. Caveats
• Not affiliated with AWS
• No expert in AWS
• Not extensive cover of CF

3. World of AWS

4. Before We Start
• AWS Account
• AWS Management Console
• IAM Keys
• AWS CLI
• Boto (Python)

5. What is CloudFormation?
a template (config/manifest)
in json

6. What is CloudFormation?

7. Anatomy Of A CF Template

8. Parameters

9. Mappings

10. Resources

11. Outputs

12. The Basic Sekeleton

13. Intrinsic Functions
Fn::Base64
Fn::FindInMap
Fn::GetAtt
Fn::GetAZs
Fn::Join
Fn::Select
Ref

14. Condition Functions
Fn::And

16. Other Cool Stuff
• AWS::CloudFormation::CustomResource
• AWS::CloudFormation::WaitCondition
• AWS::CloudFormation::WaitConditionHandle
• CloudFormation Helper Scripts
• cfn-init
• cfn-get-metadata
• cfn-signal

17. These are handy
• Instances Profiles
• curl http://169.254.169.254/latest/meta-data/
• Cumulus (https://github.com/cotdsa/cumulus)

18. How Do We Automate?

19. A Typical Scenario
• Already has a production environment
• Possible have RDS or DB instance
• Plenty of application servers
• Deployment is difficult

20. Script Build First

21. Then CloudFormation

22. Deploying

23. Deployment Pipeline

24. Deployment Pipeline

25. Quick Demo

26. Why Is This Important?
• Highly auditable
• [Cruelly] consistent & predictable
• Conveniently reproducible
!
• Immutable Servers
• Avoids EOL of Instances
• Reduces RTO
