Safe Serverless Deployments with AWS Lambda, SAM, and CodeDeploy

Deploying updates to serverless applications should not feel like a gamble. When production code changes, even minor errors can impact all of your users instantly if they are not managed carefully. This text-only course guides you through establishing safe, automated, and gradual deployment pipelines for AWS Lambda. You will learn to control how traffic shifts to your new code using AWS SAM and CodeDeploy, establishing guardrails that automatically roll back changes if issues arise. What you'll learn: - Understand the fundamentals of AWS Lambda aliases, versions, and weighted routing configurations. - Configure AWS SAM templates to define serverless resources and deployment preferences. - Implement linear and canary deployment strategies using CodeDeploy to shift traffic gradually. - Set up CloudWatch alarms to monitor function health and trigger automatic rollbacks. - Apply modern CI/CD patterns to automate serverless release pipelines safely. The course starts with foundational concepts of serverless versioning before guiding you through written explanations of configuration files, deployment strategies, and rollback mechanisms. Designed for developers and DevOps beginners looking to implement reliable serverless workflows, this course requires no prior deployment experience.
