Today AWS is announcing the public preview of AWS Serverless Application Model CLI (AWS SAM CLI) support for local development and testing of AWS Cloud Development Kit (AWS CDK) projects. AWS SAM and AWS CDK are both open-source frameworks for building applications using infrastructure as code (IaC). AWS SAM is template-based using JSON or YAML, […]

This blog post is part 3 of Getting started with serverless for developers, helping developers to start building serverless applications from their IDE. In the previous post, I introduce AWS Lambda and show how functions are designed to run business logic for serverless applications. In this blog post, you see how to access that business […]

AWS Step Functions recently introduced a new data flow simulator to model input and output path processing. This new feature makes it easier to evaluate JSON-based input and output data as it passes through a state, helping to build workflows faster. Developers build Step Functions workflows to orchestrate multiple services into business-critical applications with minimal […]

The AWS Serverless Application Model (AWS SAM) is an open-source framework for building serverless applications using infrastructure as code (IaC). Using shorthand syntax, developers declare AWS CloudFormation resources or specialized serverless resources that are transformed to infrastructure during deployment. AWS SAM commands list AWS SAM’s companion, the AWS SAM Command Line Interface (CLI), provides a […]

This blog is part 2 of “Getting started with serverless for developers“, helping developers start building serverless applications from their IDE. In part 1 you learn why developers need serverless technologies and which challenges serverless technologies help to solve. You are introduced to an example serverless application. Deploying this application to your AWS account in […]

With cross-Region event routing in EventBridge, you can now route events from any AWS Region to other supported Regions. This post explains how to configure cross-Region event routing in the console and CLI and explains how to restrict access to routing capabilities. Finally, I walk through an example you can deploy to your AWS account.

In this blog post, you learn how to control concurrency in a distributed system. You implement a semaphore using Step Functions and DynamoDB Conditional Expressions. Finally, you use EventBridge to trigger lock cleanup when you encounter failure.

The AWS Serverless team is excited to bring you the second annual serverless-first event, Serverless Live, on May 19. We’ll be livestreaming technical deep dives, demos, and live Q&A to help you get the most out of the cloud. The event opens with a keynote by Adrian Cockcroft, VP of Sustainability Architecture. It’s followed by […]

Update : You can now find the supporting GitHub repository to this series. Part 2: The business logic Part 3: The front door Part 4: Local developer workflow Part 5: Sandbox developer account Developers around the world are already running serverless applications in production without worrying about servers. This new getting started series is for […]

This blog post outlines a general approach to debugging Lambda performance issues and errors. This provides a repeatable process for isolating and resolving problems in your serverless workloads. Using the walkthrough of the Coffee Lookup application, I show how to reproduce a production bug, isolate the cause of errors, and then isolate the performance issue.
