Mutual TLS (mTLS) for API Gateway is generally available today at no additional cost. It’s available in all AWS commercial Regions, AWS GovCloud (US) Regions, and China Regions. It supports configuration via the API Gateway console, AWS CLI, SDKs, and AWS CloudFormation.

AWS Step Functions now integrates with AWS X-Ray to provide a comprehensive tracing experience for serverless orchestration workflows. Step Functions allows you to build resilient serverless orchestration workflows with AWS services such as AWS Lambda, Amazon SNS, Amazon DynamoDB, and more. Step Functions provides a history of executions for a given state machine in the AWS […]

This blog post walks through a sample application repo and explains the process for retrieving a signed URL from S3. It explains how to the test the URLs in both Postman and in a web application. Finally, I explain how to add authentication and make uploaded objects publicly accessible.

Amazon API Gateway is often used for managing access to serverless applications. Additionally, it can help developers reduce code and increase security with features like AWS WAF integration and authorizers at the API level. Because more is handled by API Gateway, developers tell us they would like to see more data points on the individual […]

AWS Step Functions allows you to create serverless workflows that orchestrate your business processes. Step Functions stores data from workflow invocations as application state. Today we are increasing the size limit of application state from 32,768 characters to 256 kilobytes of data per workflow invocation. The new limit matches payload limits for other commonly used […]

This guide demonstrates creating and deploying a production ready document scanning application. It allows users to manage projects, upload images, and generate a PDF from detected text. The sample can be used as a template for building expense tracking applications, handling forms and legal documents, or for digitizing books and notes. The frontend application is […]

Previously in this series, you deploy a simple workflow for processing image uploads in the Happy Path web application. In this post, you add progressively more complex functionality by deploying new versions of workflows.

Over the last year, I have been talking about “storage first” serverless patterns. With these patterns, data is stored persistently before any business logic is applied. The advantage of this pattern is increased application resiliency. By persisting the data before processing, the original data is still available, if or when errors occur. Common pattern for […]

This post focuses on the business logic layer of the Happy Path application. I introduce Step Functions and show how you can use Amazon States Languages (ASL) to define state machines.

In this post, I introduce the Happy Path example web application. I show the main features of the application, enabling end-users to upload maps and photos to the backend application.
