The default behavior for stream processing in Lambda functions enables entire batches of messages to succeed or fail. You can also use batch bisecting functionality to retry batches iteratively if a single message fails. Now with custom checkpoints, you have more control over handling failed messages.

With tumbling windows, you can calculate aggregate values in near-real time for Kinesis data streams and DynamoDB streams. Unlike existing stream-based invocations, state can be passed forward by Lambda invocations. This makes it easier to calculate sums, averages, and counts on values across multiple batches of data.

Lambda now supports self-hosted Kafka as an event source so you can invoke Lambda functions from messages in Kafka topics to integrate into other downstream serverless workflows. This post shows how to configure a self-hosted Kafka cluster on EC2 and set up the network configuration. I also cover how to set up the event source mapping in Lambda and test a function to decode the messages sent from Kafka.

In this post, I explain how to use AWS Lambda layers and extensions with Lambda functions packaged and deployed as container images. Previously, Lambda functions were packaged only as .zip archives. This includes functions created in the AWS Management Console. You can now also package and deploy Lambda functions as container images. You can use […]

During the last few weeks, the AWS serverless team has been releasing a wave of new features in the build-up to AWS re:Invent 2020. This post recaps some of the most important releases for serverless developers. re:Invent is virtual and free to all attendees in 2020 – register here. See the complete list of serverless […]

This is courtesy of Alexandre Pinhel, Specialist SA Manager, in collaboration with Guillaume Marchand and Luke Hargreaves, Solutions Architects. Amazon Simple Queue Service (Amazon SQS) is a fully managed message queuing service. It enables you to decouple and scale microservices, distributed systems, and serverless applications. A commonly used feature of Amazon SQS is dead-letter queues. The […]

Today, AWS is introducing Synchronous Express Workflows for AWS Step Functions. This is a new way to run Express Workflows to orchestrate AWS services at high-throughput. Developers have been using asynchronous Express Workflows since December 2019 for workloads that require higher event rates and shorter durations. Customers were looking for ways to receive an immediate […]

With the release of AVX2 for Lambda, customers can now run AVX2-optimized workloads while benefitting from the pay-for-use, reduced operational model of AWS Lambda. This feature is provided at no additional cost.

AWS Step Functions now integrates with Amazon API Gateway to enable backend orchestration with minimal code and built-in error handling. API Gateway is a fully managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at any scale. These APIs enable applications to access data, business logic, or functionality […]

This post shows you how to use the new features Amazon EventBridge resource policies that make it easier to build applications that work across accounts.  Resource policies provide you with a powerful mechanism for modeling your event buses across multiple accounts, and give you fine-grained control over EventBridge API invocations.
