4. Technology Investment in Action Vendors Infrastructure Applications and Services Deployment Workflows Tech Stack
5. ClickOps The Status-Quo
6. The Problems Institutional Knowledge Loss Separate locations for documentation Takes a lot of time to replicate a single deployment for testing purposes Prone to errors due to manual operations Quite challenging to figure out which components connect to which service/domain
7. Enter Infrastructure as Code Declare infrastructure setup with code Acts as a living documentation Reports configuration drifts from code vs provider (cloud, services, etc.) Easier to hand-off between engineers Can replicate a setup instantly Vendor agnostic
8. IaC in Action Institutional Knowledge Loss & separate locations for documentation All setups are declared as code, this serves as a living documentation
9. IaC in Action Takes a lot of time to replicate a single deployment for testing purposes It can be as simple as copying the relevant code blocks, change the name, and apply terraform configuration to replicate a deployment
10. IaC in Action Prone to errors due to manual operations Everything is declared as code, all changes are reported before asking for an explicit confirmation to apply configurations
11. IaC in Action Quite challenging to figure out which component connects to which service/domain Terraform allows resource dependencies, this paints a clear picture of which resources are dependent on some other resources
12. Money Talks A DevOps team of 8 persons 3 deployments / engineer / day Total of 100 services By adopting terraform organizations can save operational costs up to 415,300.8 USD / year https://karnwong.me/posts/2023/11/reduce-operational-costs-with-terraform/
13. FinOps Integration Infracost See cost breakdown from terraform project Can be integrated with CI/CD Without tools, I managed to save 6200 USD / month . With Terrform and its ecosystem, it could be so much more.
