Infrastructure as Code (IaC) is designed for templates to be reused by multiple teams and individuals so they can scale best practices. But if everyone is hand-crafting unique templates, how do you ensure your deployed applications are compliant and secure? As a principal software engineer on the Serverless enablement team at Liberty Mutual, I will show you how we create Well-Architected “golden paths” through AWS SAM and CDK templates, allowing thousands of engineers to rapidly deliver business value every day. This talk will cover AWS SAM and CDK Pattern development, enabling constraints in serverless templates, Inner Source contributions, and how to adhere to Well-Architected best practices. Attendees will walk away with a better understanding of how we build these patterns, engage with the community, assess the Well-Architected status of different applications, and drive serverless culture forward.
