Retries are still a best practice for serverless architectures

Serverless architectures handle retries differently than traditional server-based systems. While retries can cause metastability issues in fixed-capacity servers by creating endless overload states, serverless platforms like AWS Lambda and DynamoDB can scale infinitely to handle increased traffic from retries. However, any non-scalable third-party services in the critical path can still create bottlenecks that negate these benefits, often remaining hidden until system failure occurs.
