AWS SAM(Serverless Application Model) 을 이용한 백오피스 마이그레이션 (현창훈, HBSmith) :: AWS DevDay 2018
The document discusses serverless architectures on AWS. It begins with an introduction to why serverless is useful, specifically that it allows developers to focus on code without worrying about provisioning or managing infrastructure. Next, it provides guidance on migrating applications to serverless, including using AWS SAM and Serverless Express to deploy Node.js apps as Lambda functions. It also discusses using Infrastructure as Code with tools like CloudFormation to manage serverless resources. The document concludes with information about AWS SAM, serverless databases, and using IaC to implement continuous delivery of serverless applications.
