Low-latency, high-throughput SQS event processing with AWS Lambda provisioned mode

Customers building event-driven applications on AWS rely on Amazon Simple Queue Service (Amazon SQS) and AWS Lambda event source mappings (ESMs) to process millions of events every day. The fully managed polling infrastructure of ESMs eliminates the need to write and maintain custom code. You can focus on business logic while Lambda handles scaling, batching, […]

Integrating Event Source Mappings with AWS Lambda tenant isolation mode

Building event-driven multi-tenant SaaS applications typically requires compute isolation between tenants to prevent data leakage, maintain security boundaries, and ensure compliance. Traditionally, you had to choose between two approaches: sharing execution environments across tenants (risking cross-tenant contamination of in-memory state) or managing separate Lambda functions per tenant (which introduces operational overhead, increasing costs, and complicating […]

Multi-Region event-driven failover architecture with Amazon EventBridge and Route 53

Multi-Region Event-Driven Failover Architecture with Amazon EventBridge and Route 53 Event-driven architectures enable applications to respond to events in real-time, providing scalability and loose coupling between components. However, ensuring high availability across multiple AWS regions requires careful design of failover mechanisms. This post demonstrates how to build a resilient multi-region event-driven architecture using Amazon EventBridge, […]

Enabling high availability of Amazon EC2 instances on AWS Outposts servers (Part 3)

This post is part 3 of the three-part series ‘Enabling high availability of Amazon EC2 instances on AWS Outposts servers’. We provide you with code samples and considerations for implementing custom logic to automate Amazon Elastic Compute Cloud (EC2) relaunch on Outposts servers. This post focuses on guidance for using Outposts servers with third party storage for boot […]

Serverless ICYMI Q4 2025

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.

More room to build: serverless services now support payloads up to 1 MB

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.

Serverless strategies for streaming LLM responses

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.

Implementing message prioritization with quorum queues on Amazon MQ for RabbitMQ

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 […]

Building resilient multi-tenant systems with Amazon SQS fair queues

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 […]
