Many organizations use a multi-account strategy for stream processing applications. This involves decomposing the overall architecture into a single producer account and many consumer accounts. Within AWS, in the producer account, you can use Amazon Managed Streaming for Apache Kafka (Amazon MSK), and in their consumer accounts have AWS Lambda functions for event consumption. This blog post explains how you can trigger Lambda functions from a cross-acc ..read more

This post is written by Julian Wood, Principal Developer Advocate, and Dan Fox, Principal Specialist Serverless Solutions Architect. AWS Lambda supports multiple programming languages through the use of runtimes. A Lambda runtime provides a language-specific execution environment, which provides the OS, language support, and additional settings, such as environment variables and certificates that you can access from your function code. You can use managed runtimes that Lambda provides or build your own. Each major programming language release has a separate managed runtime, with a un ..read more

This post is written by Pascal Vogel, Solutions Architect, and Andrea Amorosi, Senior Solutions Architect. You can now develop AWS Lambda functions using the Node.js 20 runtime. This Node.js version is in active LTS status and ready for general use. To use this new version, specify a runtime parameter value of nodejs20.x when creating or updating functions or by using the appropriate container base image. You can use Node.js 20 with Powertools for AWS Lambda (TypeScript), a developer toolkit to implement serverless best practices and increase developer velocity. Powertools for AWS Lambda inclu ..read more

This post is written by Rakshith Rao, Senior Solutions Architect. AWS Lambda now supports Amazon Linux 2023 (AL2023) as a managed runtime and container base image. Named provided.al2023, this runtime provides an OS-only environment to run your Lambda functions. It is based on the Amazon Linux 2023 minimal container image release and has several improvements over Amazon Linux 2 (AL2), such as a smaller deployment footprint, updated versions of libraries like glibc, and a new package manager. What are OS-only Lambda runtimes? Lambda runtimes define the execution environment where your function r ..read more

AWS Lambda is improving the automatic scaling behavior when processing data from Apache Kafka event-sources. Lambda is increasing the default number of initial consumers, improving how quickly consumers scale up, and helping to ensure that consumers don’t scale down too quickly. There is no additional action that you must take, and there is no additional cost. Running Kafka on AWS Apache Kafka is a popular open-source platform for building real-time streaming data pipelines and applications. You can deploy and manage your own Kafka solution on-premises or in the cloud on Amazon EC2. Amazon Man ..read more

This post was written by Anton Aleksandrov, Principal Solutions Architect, and Tarun Rai Madan, Senior Product Manager. Today, AWS is announcing that AWS Lambda supports up to five times faster polling scale-up rate for spiky Lambda workloads configured with Amazon Simple Queue Service (Amazon SQS) as an event source. This feature enables customers building event-driven applications using Lambda and SQS to achieve more responsive scaling during a sudden burst of messages in their SQS queues, and reduces the need to duplicate Lambda functions or SQS queues to achieve faster ..read more

Commonly known as reverse APIs or push APIs, webhooks provide a way for applications to integrate to each other and communicate in near real-time. It enables integration for business and system events. Whether you’re building a software as a service (SaaS) application integrating with your customer workflows, or transaction notifications from a vendor, webhooks play a critical role in unlocking innovation, enhancing user experience, and streamlining operations. This post explains how to ..read more

This post is written by Anton Aleksandrov, Principal Serverless Solutions Architect,  and Shridhar Pandey, Senior AWS Lambda Product Manager. AWS Lambda runtimes use the Lambda Runtime API to communicate with the Lambda service. Runtimes use it to retrieve inbound events to be processed by the function handler, return successful handler responses to the Lambda service, and report failures. This post shows how to intercept inbound events and outbound responses without changing function code, using the Runtime API proxy pattern. This approach enables security vendors and engineering te ..read more

This post is written by Pascal Vogel, Solutions Architect, and Martin Sakowski, Senior Solutions Architect. Large language models (LLMs) are proving to be highly effective at solving general-purpose tasks such as text generation, analysis and summarization, translation, and much more. Because they are trained on large datasets, they can use a broad generalist knowledge base. However, as training takes place offline and uses publicly available data, their ability to access specialized, private, and up-to-date knowledge is limited. One way to improve LLM knowledge in a specific domain is fine-tu ..read more
