There are multiple factors to consider when tuning a federated GQL system. You must be aware of trade-offs when deciding on factors like the runtime environment of Lambda functions. An extensive testing strategy can help you scale systems and narrow down issues quickly. Well-defined testing can also keep pipelines clean of false-positive blockages.

Having visibility on your AWS resources is the key to operating and growing successfully. In this first part of this series on serverless governance, I describe how you can get this visibility by using tags to organize and group your resources, and ease the search and management of related resources.

This series of blog posts uses the AWS Well-Architected Tool with the Serverless Lens to help customers build and operate applications using best practices. In each post, I address the serverless-specific questions identified by the Serverless Lens along with the recommended best practices. See the introduction post for a table of contents and explanation of the example application. PERF 1. Optimizing […]

Beginning July 19, 2021, the Java 8 managed runtime in AWS Lambda will migrate from the current Open Java Development Kit (OpenJDK) implementation to the latest Amazon Corretto implementation.

This post focuses on ingesting data into Kinesis Data Streams. I explain the two approaches used by the Alleycat frontend and the simulator application and highlight other approaches that you can use. I show how messages are routed to shards using partition keys. Finally, I explore additional factors to consider when ingesting data, to improve efficiency and reduce cost.

This post is written by Brian Zambrano, Enterprise Solutions Architect and Srinivasa Atta, Sr. Technical Account Manager With microservice architectures, multiple teams within an organization often build different parts of an application. Different teams may own functionality for a given business segment. An effective pattern to support this is a centrally managed public API. This […]

The recently launched Serverless Patterns Collection is a repository of serverless examples that demonstrate integrating two or more AWS services. Each pattern uses either the AWS Serverless Application Model (AWS SAM) or AWS Cloud Development Kit (AWS CDK). These simplify the creation and configuration of the services referenced. The Serverless Patterns Collection is both an educational […]

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 blog post outlines a general approach to debugging Lambda performance issues and errors. This provides a repeatable process for isolating and resolving problems in your serverless workloads. Using the walkthrough of the Coffee Lookup application, I show how to reproduce a production bug, isolate the cause of errors, and then isolate the performance issue.
