DynamoDB Design Patterns for Single Table Design by
DynamoDB is the beast that combined with the right design patterns unlocks the potential of unlimited scalability, performance, and low price. However, designing DynamoDB data models can be tricky.


Why you shouldn't use AWS API Gateway HTTP API
Less than a year passed since AWS announced a new API type for API Gateway, namely HTTP API. Here I'd like to share my experience with HTTP API utilization. Since AWS API Gateway has proved its efficiency (especially in serverless architecture), numerous projects adopted this AWS service.


"Even simple serverless applications have complex architecture diagrams", so what?
A common complaint I have heard about serverless applications is that they tend to look really complicated on architecture diagrams, with many moving parts. But does it mean serverless applications are more complex compared to their serverful counterparts?


How do you build APIs that consume cross account resources (and do it securely)? by George Mao
