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 […]

Cold starts are an important consideration when building applications on serverless platforms. In AWS Lambda, they refer to the initialization steps that occur when a function is invoked after a period of inactivity or during rapid scale-up. While typically brief and infrequent, cold starts can introduce additional latency, making it essential to understand them, especially […]

Modern applications increasingly rely on Serverless technologies such as Amazon Web Services (AWS) Lambda to provide scalability, cost efficiency, and agility. The Serverless Applications Lens for the AWS Well-Architected Framework focuses on how to design, deploy, and architect your Serverless applications to overcome some of these challenges. Powertools for AWS Lambda is a developer toolkit that […]

This blog post discusses the AWS Lambda as orchestrator anti-pattern and how to redesign serverless solutions using AWS Step Functions with native integrations.

This post demonstrates how you can modernize legacy SOAP applications using Amazon API Gateway and AWS Lambda to create bidirectional proxy architectures that enable integration between SOAP and REST systems without disrupting existing business operations. Many organizations today face the challenge of maintaining critical business systems that were built decades ago. These legacy applications power […]

Many organizations implement intelligent document processing pipelines in order to extract meaningful insights from an increasing volume of unstructured content (such as insurance claims, loan applications and more). Traditionally, these pipelines require significant engineering efforts, as the implementation often involves using several machine learning (ML) models and orchestrating complex workflows. As organizations integrate these pipelines […]

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 […]

In this post, learn how the new Powertools for AWS Lambda (TypeScript) Parser utility can help you validate payloads easily and make your Lambda function more resilient. Validating input payloads is an important aspect of building secure and reliable applications. This ensures that data that an application receives can gracefully handle unexpected or malicious inputs […]
