Thinking Asynchronously • Eric Johnson • GOTO 2020

This presentation was recorded at GOTO Oslo 2020. #GOTOcon #GOTOoslo https://goto-oslo.com Eric Johnson - Highly Entertaining Serverless Fanatic with Brilliant Insights; Senior Developer Advocate at AWS Serverless ABSTRACT Speed matters, and developers are challenged to reduce latency in their applications at every turn. In traditional synchronous programming patterns, users are asked to monitor the spinning wheel as the application moves from one task to the next until a response can be returned. However, developers can reclaim these precious milliseconds by learning to think asynchronously. Asynchronous patterns challenge developers to evaluate what tasks require the client to wait versus what can be done after the fact. When developing serverless applications on AWS this process is made easier by the asynchronous and polling patterns that are native to AWS Lambda. In this session I will demonstrate taking an existing translation application that is synchronous and modifying it to use asynchronous patterns. This will be accomplished using Amazon DynamoDB Streams [...] TIMECODES 0:00 Introduction 2:37 Application elements 5:36 Thinking asynchronously 11:40 Making this work on AWS 14:21 Other "storage first" options 15:01 Event data 18:07 Resulting Data 23:23 Asynchronous demo 31:13 More reliability - Lambda Destinations 32:46 More reliability - Error correction 34:25 Extending via the pattern 37:05 Wrap up Download slides and read the full abstract here: https://goto-oslo.com/2020/sessions/1297/thinking-asynchronously-virtual https://twitter.com/GOTOcon https://www.linkedin.com/company/goto- https://www.facebook.com/GOTOConferences #Serverless #DynamoDBStreams #EventBridge #AWS #Programming Looking for a unique learning experience?
