3. What is Serverless?
4. What is Serverless? Serverless is the concept of outsourcing the base and management of your infrastructure
5. What is Serverless? • No direct infrastructure management
6. What is Serverless? - Service as a Service AWS
7. What is Serverless? • No direct infrastructure management • Scalable • Highly available
11. What is Serverless? • No direct infrastructure management • Scalable • Highly available • Zero Idle Capacity
12. Zero Idle Capacity • No wasted resources • Only alive during processing time • Disposed after process completed
13. Zero Idle Capacity
14. What is Serverless? • No direct infrastructure management • Scalable • Highly available • Zero Idle Capacity • Can be cost efficient • Requires comprehensive architecture design
16. GET POST
17. Terraform
18. Terraform • Infrastructure as Code (IaC) - Blueprint
21. Code reusability Keep your codebase DRY
22. Terraform Reusability
23. Terraform Modules
24. Terraform Modules
25. • Infrastructure as Code (IaC) - Blueprint Terraform • Automation - Reduced provisioning errors • Consistency between environments
26. Account A Account B Engineer Engineer
27. Account A Account B IaC Runner
28. • Infrastructure as Code (IaC) - Blueprint • Automation - Reduced provisioning errors • Consistency between environments • Cloud agnostic • Organization/Documentation Terraform

30. • Infrastructure as Code (IaC) - Blueprint • Automation - Reduced provisioning errors • Consistency between environments • Cloud agnostic • Organization/Documentation • Infrastructure as Code (IaC) - Blueprint Terraform • Enforce team/company standards
31. Enforce company/team standards The best way to prevent fatal mistakes, is to not allow a scenario where they can happen*
32. Enforce company/team standards • Security policies • Security groups • Default behaviors • Network
33. • Infrastructure as Code (IaC) - Blueprint • Automation - Reduced provisioning errors • Consistency between environments • Cloud agnostic • Organization/Documentation • Enforce team/company standards Terraform • Version your infrastructure
34. Serverless and Terraform
35. • Focus on development • Faster deployment and provisioning ◦ Similar resources with modules
38. • Focus on development • Faster deployment and provisioning ◦ Similar resources with modules • Better architecture overview
39. • Focus on development • Faster deployment and provisioning ◦ Similar resources with modules • Better architecture overview
