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 [...]

Really good explanation with neat architecture diagrams and a sample app demonstrating the serverless idea. Thank you very much.

[@jonashansen2512]

Like the idea, essentially asynchronous event sourcing :)

[@juancpgo]

Eric, this was plain awesome. The simplicity and efficiency of your architecture mentality is really exciting to me. I'm eagerly waiting for DynamoDB integrations for HTTP APIs!!

[@EricJohnson-lr2tl]

Meeeeeee toooooo!

[@yarielhernandez8277]

una de las mejores conferencias que he visto, excelente, para mi todo un cambio de paradigma recién me inicio en serverless y AWS, gracias

[@SteakSolid]

Awesome presentation. Very easy to digest. Thanks

[@karpuzye]

great talk.. thnx

[@gasparsigma]

That's cool, thanks for breaking down the use of lambdas it was easy to understand. But couldn't the exact same could be achieved as having each of these lambdas as a function in a single server with fire and forget logic?

[@EricJohnson-lr2tl]

Yes they could, BUT you would pay for idle time on the server. In this model, you ONLY pay for the invocation time. This is but one advantage of serverless, but a biggie.

​@@EricJohnson-lr2tl, would you be so kind to share the code from the sample you used?
