Users usually package their function code as container images when using machine learning (ML) models that are larger than 250 MB, which is the Lambda deployment package size limit for zip files. In this post, we demonstrate an approach that downloads ML models directly from Amazon S3 into your function’s memory so that you can continue packaging your function code using zip files.

In this post, we show how to use Step Functions Distributed Map to process Amazon S3 objects and export results to Amazon S3 Tables, creating a scalable and maintainable data processing pipeline.

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.

Amazon EC2 offers AMD-based instances built on multiple generations of AMD EPYC processors. This post focuses on optimization strategies for the 3rd and 4th generation families, which provide enhanced capabilities for compute and memory-intensive workloads.

This post demonstrates how you can connect CloudFront with a Private REST API in Amazon REST API Gateway using a VPC origin.

This post presents architectural best practices for building resilient serverless applications, demonstrated through a multi-Region serverless authorizer implementation.

This post explores two complementary approaches for non-real-time scenarios: buffered asynchronous processing for time-intensive individual requests, and batch processing for scheduled or event-driven workflows.

This two-part series explores the different architectural patterns, best practices, code implementations, and design considerations essential for successfully integrating generative AI solutions into both new and existing applications. In this post, we focus on patterns applicable for architecting real-time generative AI applications.

AWS Lambda cold start latency can impact performance for latency-sensitive applications, with function initialization being the primary contributor to startup delays. Lambda SnapStart addresses this challenge by reducing cold start times from several seconds to sub-second performance for Java, Python, and .NET runtimes with minimal code changes. This post explains SnapStart’s underlying mechanisms and provides performance optimization recommendations for applications using this feature.

Imagine an AI assistant that doesn’t just respond to prompts – it reasons through goals, acts, and integrates with real-time systems. This is the promise of agentic AI. According to Gartner, by 2028 over 33% of enterprise applications will embed agentic capabilities – up from less than 1% today. While early generative AI efforts focused […]
