Stay current with the latest serverless innovations that can transform your applications. In this 31st quarterly recap, discover the most impactful AWS serverless launches, features, and resources from Q4 2025 that you might have missed.

To support cloud applications that increasingly depend on rich contextual data, AWS is raising the maximum payload size from 256 KB to 1 MB for asynchronous AWS Lambda function invocations, Amazon Amazon SQS, and Amazon EventBridge. Developers can use this enhancement to build and maintain context-rich event-driven systems and reduce the need for complex workarounds such as data chunking or external large object storage.

Modern generative AI applications often need to stream large language model (LLM) outputs to users in real-time. Instead of waiting for a complete response, streaming delivers partial results as they become available, which significantly improves the user experience for chat interfaces and long-running AI tasks. This post compares three serverless approaches to handle Amazon Bedrock LLM streaming on Amazon Web Services (AWS), which helps you choose the best fit for your application.

Quorum queues are now available on Amazon MQ for RabbitMQ from version 3.13. Quorum queues are a replicated First-In, First-Out (FIFO) queue type that uses the Raft consensus algorithm to maintain data consistency. Quorum queues on RabbitMQ version 3.13 lack one key feature compared to classic queues: message prioritization. However, RabbitMQ version 4.0 introduced support […]

Today, AWS introduced Amazon Simple Queue Service (Amazon SQS) fair queues, a new feature that mitigates noisy neighbor impact in multi-tenant systems. With fair queues, your applications become more resilient and easier to operate, reducing operational overhead while improving quality of service for your customers. In distributed architectures, message queues have become the backbone of […]

AWS Lambda now provides native support for Apache Avro and Protocol Buffers (Protobuf) formatted events with Apache Kafka event source mapping (ESM) when using Provisioned Mode. The support allows you to validate your schema with popular schema registries. This allows you to use and filter the more efficient binary event formats and share data using […]

Event-driven architectures with message brokers need careful attention to security best practices. Amazon MQ for RabbitMQ combined with AWS Lambda enables serverless event processing. However, implementing defense in depth and least privilege principles necessitates a clear understanding of networking requirements. This is particularly important when working with different subnet types and their impact on service […]

Currently, the federation plugin on Amazon MQ for RabbitMQ connects to publicly available upstream brokers only. This post explains how to implement federation for Amazon MQ RabbitMQ Private Brokers using Network Load Balancers (NLB). The steps allow private brokers to communicate with each other to create a distributed system.

Welcome to the 28th edition of the AWS Serverless ICYMI (in case you missed it) quarterly recap. At the end of a quarter, we share the most recent product launches, feature enhancements, blog posts, videos, live streams, and other interesting things that you might have missed! In case you missed our last ICYMI, check out […]

This post is authored by Anton Aleksandrov, Principal Solution Architect, AWS Serverless and Daniel Abib, Senior Specialist Solutions Architect, AWS Serverless application developers may commonly encounter scenarios where they need to transport large payloads, especially when building modern cloud applications that need rich data. Examples include analytics services with detailed reports, e-commerce platforms with extensive […]
