Improve API discoverability with the new Amazon API Gateway Portal
In this post, we will show how you can use the new portal feature to create customizable portals with enhanced security features in minutes, with APIs from multiple accounts, without managing any infrastructure.
Building responsive APIs with Amazon API Gateway response streaming
Today, AWS announced support for response streaming in Amazon API Gateway to significantly improve the responsiveness of your REST APIs by progressively streaming response payloads back to the client. With this new capability, you can use streamed responses to enhance user experience when building LLM-driven applications (such as AI agents and chatbots), improve time-to-first-byte (TTFB) performance for web and mobile applications, stream large files, and perform long-running operations while reporting incremental progress using protocols such as server-sent events (SSE).
Python 3.14 runtime now available in AWS Lambda
AWS Lambda now supports Python 3.14 as both a managed runtime and container base image. Python is a popular language for building serverless applications. Developers can now take advantage of new features and enhancements when creating serverless applications on Lambda.
Building serverless applications with Rust on AWS Lambda
Today, AWS Lambda is promoting Rust support from Experimental to Generally Available. This means you can now use Rust to build business-critical serverless applications, backed by AWS Support and the Lambda availability SLA.
AWS Lambda now supports Java 25
You can now develop AWS Lambda functions using Java 25 either as a managed runtime or using the container base image. This blog post highlights notable Java language features, Java Lambda runtime updates, and how you can use the new Java 25 runtime in your serverless applications.
Orchestrating big data processing with AWS Step Functions Distributed Map
In this post, you’ll learn how to use AWS Step Functions Distributed Map to process Amazon Athena data manifest and Parquet files through a step-by-step demonstration.
Optimizing nested JSON array processing using AWS Step Functions Distributed Map
In this post, we explore how to optimize processing array data embedded within complex JSON structures using AWS Step Functions Distributed Map. You’ll learn how to use ItemsPointer to reduce the complexity of your state machine definitions, create more flexible workflow designs, and streamline your data processing pipelines—all without writing additional transformation code or AWS Lambda functions.
Introducing AWS Lambda event source mapping tools in the AWS Serverless MCP Server
Modern serverless applications increasingly rely on event-driven architectures, where AWS Lambda functions process events from various sources like Amazon Kinesis, Amazon DynamoDB Streams, Amazon Simple Queue Service (Amazon SQS), Amazon Managed Streaming for Apache Kafka (Amazon MSK), and self-managed Apache Kafka. Although event source mappings (ESM) offer a powerful mechanism for integrating AWS Lambda with […]
Processing Amazon S3 objects at scale with AWS Step Functions Distributed Map S3 prefix
In this post, you’ll learn how to process Amazon S3 objects at scale with the new AWS Step Functions Distributed Map S3 prefix and transformation capabilities.
Enhance the local testing experience for serverless applications with LocalStack
Today, we’re excited to announce new capabilities that further simplify the local testing experience for Lambda functions and serverless applications through integration with LocalStack, an AWS Partner, in the AWS Toolkit for Visual Studio Code. In this post, we will show you how you can enhance your local testing experience for serverless applications with LocalStack using AWS Toolkit.
