Learn how to use CloudFront functions and the newly released CloudFront KeyValueStore to build a simple and fully serverless URL shortener.

Learn how to use the newly released advanced logging controls to consolidate your Lambda logs into a single log group. This overcomes one of the most painful aspects of CloudWatch Logs Insights: combing through hundreds of Log groups.

Testing Serverless applications end-to-end is difficult. Testing distributed systems is difficult. But with the right tools, it can be made easier. Learn how to use Momento Topics to test that your application(s) produces the EventBridge events you expect.

Learn how to reliably publish domain events in Serverless applications using the Transactional Outbox Pattern. Get the reliability your events deserve with DynamoDB Streams and Transactions while keeping your domain layer clean and complexity low.

Do you often hear people advocating "testing in production" and wonder how that is possible? One piece of the puzzle is canary deployments. This SST-focused tutorial will teach you how to implement canary deployments using AWS CodeDeploy and Lambda aliases.

Debugging applications that write to DynamoDB just got a lot easier. Learn how to use the newly released EventBridge pipes to log all item-level modifications in a DynamoDB table to a CloudWatch log group, for debugging or audit purposes.

Learn how to migrate DynamoDB tables with zero downtime and no data loss. AWS recently released new functionality to ease migrations with native imports from S3. There are a lot of guides on how to do this with ClickOps. But, I prefer to use an Infrastructure-as-Code tool such as AWS CDK to manage my resources. While digging around, I found yet-to-be-announced functionality in CloudFormation to do this.

Continuously adding services and resources without thinking about separation can lead to a tangled web of Lambda functions, DynamoDB tables, API Gateways, SQS Queues, and other services. Learn how to separate your serverless infrastructure into more manageable chunks, using CloudFormation Outputs and SSM parameters. See examples for AWS CDK, AWS SAM, Serverless Framework, and Terraform.

I use Trello for all kinds of personal stuff, one of which is keeping track of recipes and grocery lists. After planning which meals to cook and buy groceries for, a lot of manual work goes into checking every recipe and adding the ingredients to the grocery shopping list. Manual stuff is tedious, so I automated it with AWS Lambda. Read on to find out how!

Long gone are the days when you had to keep long-lived access keys in your CI/CD pipelines to deploy to AWS. Learn how to use GitHub Actions and OIDC to securely deploy to AWS
