https://youtu.be/oo24caqVgMk Idem is an open source, stateful configuration management platform written in Python from the inventor of Salt. This talk will go over: - Plugin Oriented Programming (POP) brief overview - Idem's place in the POP ecosystem - Idem syntax and workflow - Microsoft Azure Infrastructure as Code (IaC) - Idem Roadmap

1. Infrastructure as Code with Idem
Microsoft Azure

4. Salt Cloud

5. Salt Cloud
● Only for cloud "compute" (instances, virtual machines)
● Different workflow than the rest of Salt
○ Providers
○ Profiles
○ Maps
● Not the same Jinja "support" as the rest of Salt (no execution modules)
● Usually implemented in orchestration states
○ Infrastructure with state modules
○ Virtual machineswith Salt Cloud maps
● Some state modules exist for compute

7. The Birth of Plugin Oriented Programming (POP)
● Identified Problems:
○ Huge projects
○ Complex code
○ Slow releases
○ The Mythical Man-Month

8. Reference: Salt Plugins

9. Plugin Oriented Programming (POP)
● Unix Philosophy
○ Do one thing. Do it well.
○ Write programs that work together.
○ Write programs that talk the same language (common interface).
● Everything is a plugin!
● Merge all the things!
● Result:
○ Smallerprojects
○ Fasterreleases
○ More innovation

12. Idem
● Short for "Idempotent"
● Configuration management
● Execution Modules - “do things”
● State Modules - “do things”, but only if they need to be done
● Perfect for cloud... separate repositories

13. Idem: Terminology
● Execution Modules - “do things”
DISCLAIMER:
This is not an Idem module.
This is only for learning the concepts.

15. Idem Cloud
● For all cloud services and APIs
○ IaaS
○ PaaS
○ FaaS
○ DBaaS
○ etc.
● Same workflow for all the things

16. Demos:
● Training wheels
● Big boy bike
● Crazy unicycle guy

19. The Future of Idem
● More "clouds"!
○ libvirt, vagrant, virtualbox, vultr
○ AWS, GCP, OCI, etc.
○ Linode, DigitalOcean, etc.
○ OpenStack, VMware, etc.
● More configuration management!
○ System: file, service, package, etc.
● More easy...er...ness!
