This post is the final part in a 3-part series on performance optimization in Lambda. The Lambda service makes frequent performance improvements in the underlying hardware, software, and architecture of the service. This post identifies the parts of the Lambda lifecycle where developers can make the most impact on performance.

In this post, I show how the new shared memory support in AWS Batch is able to improve performance while decreasing the latency of the intra-node communication. This performance gain can also lower the cost of running jobs overall.

This post is the second in a 3-part series on performance optimization in Lambda. It explains the effect of the memory configuration on Lambda performance, and why the memory setting also controls the compute power and networking I/O available to a function.

Today AWS is announcing the public preview of AWS Serverless Application Model CLI (AWS SAM CLI) support for local development and testing of AWS Cloud Development Kit (AWS CDK) projects. AWS SAM and AWS CDK are both open-source frameworks for building applications using infrastructure as code (IaC). AWS SAM is template-based using JSON or YAML, […]

This post is written by Scott Malkie, Specialist Solutions Architect, EC2 AWS Nitro Enclaves, introduced in October 2020, are isolated compute environments. They leverage the power of the AWS Nitro System to provide isolation and attestation for sensitive data processing. Customers use Nitro Enclaves to isolate their data processing workloads, even from users with root […]

This blog post is part 3 of Getting started with serverless for developers, helping developers to start building serverless applications from their IDE. In the previous post, I introduce AWS Lambda and show how functions are designed to run business logic for serverless applications. In this blog post, you see how to access that business […]

This post is written by Scott Malkie, Specialist Solutions Architect, EC2 At re:Invent 2020, we announced Amazon EC2 Mac instances, which enable you to run on-demand macOS workloads in the AWS Cloud for the first time. Apple developers can now benefit from the scalability, elasticity, reliability, and security of the AWS Cloud and the AWS […]

AWS Step Functions recently introduced a new data flow simulator to model input and output path processing. This new feature makes it easier to evaluate JSON-based input and output data as it passes through a state, helping to build workflows faster. Developers build Step Functions workflows to orchestrate multiple services into business-critical applications with minimal […]

The AWS Serverless Application Model (AWS SAM) is an open-source framework for building serverless applications using infrastructure as code (IaC). Using shorthand syntax, developers declare AWS CloudFormation resources or specialized serverless resources that are transformed to infrastructure during deployment. AWS SAM commands list AWS SAM’s companion, the AWS SAM Command Line Interface (CLI), provides a […]
