Messaging is an important part of serverless applications and AWS services provide queues, publish/subscribe, and event routing capabilities. This post reviews the main features of SNS, SQS, and EventBridge and how they provide different capabilities for your workloads.

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.

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.

Lambda layers provide a convenient and effective way to package code libraries for sharing with Lambda functions in your account. Using layers can help reduce the size of uploaded archives and make it faster to deploy your code.

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.

This blog post demonstrates a solution that connects Salesforce to an event-driven application that uses EventBridge and Amazon AppFlow to route events. The application uses events from Salesforce as a starting point for a custom processing workflow in a Lambda function.

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.

Now Lambda supports Amazon MSK as an event source, you can invoke Lambda functions from messages in Kafka topics to integrate into your downstream serverless workflows.

Web developers commonly use relational databases in building their applications. When migrating to serverless architectures, a web developer can continue to use databases like RDS, or take advantage of other options available.
