Lambda Dynamodb X Ray
Today we re announcing general availability of aws lambda support for aws x ray.
Lambda dynamodb x ray. The lambda cold start took 461ms and 185ms to process the request. The x ray tracer this is a pattern not defined by the components used but how they send information back to the aws x ray service to help you make your application perform better when viewed through the serverless well architected lens. Go back to your aws x ray console wait for the new trace to show up. It buffers incoming data and writes it to x ray in batches reducing the processing and memory overhead required to trace invocations.

A fully well architected solution would use embedded metric format for the logs like in the julian wood reference below but i am saving that for another. As you may already know from jeff s ga post x ray is an aws service for analyzing the execution and performance behavior of distributed applications. The aws x ray daemon is an application that runs in the lambda environment and listens for udp traffic that contains segments and subsegments.
You can tell if a trace is recent by looking at its age. You can use aws x ray to trace your aws lambda functions. For further instrumentation you can bundle the x ray sdk with your function to record outgoing calls and add annotations and metadata. Out of the 185ms the dynamodb query took 73ms and the sns publish call took.
Although this shift toward more distributed architectures has unlocked many benefits it has also introduced new complexity in how the applications are operated. Select the new trace.
Modern applications are increasingly relying on compute platforms based on containers and serverless technologies to provide scalability cost efficiency and agility. In times past debugging was as straightforward as logging into. Traditional debugging methods don t work so well for microservice based applications in which there are multiple independent components running. It might take up to 30 seconds to do so.
