This post was written by Robert Zhu, Principal Developer Advocate at AWS.  This article continues a blog I posted earlier about using Load Balancers on Amazon Lightsail. In this article, I demonstrate a few common challenges and solutions when combining stateful applications with load balancers. I start with a simple WebSocket application in Amazon Lightsail […]

In this post, I discuss focus areas for load testing of serverless applications, and highlight two tools commonly used. I show how to configure Artillery with customized functions, and how to run tests to simulate load on the Ask Around Me application.

In this post, I show how to integrate the AWS Batch CLI by AWS ParallelCluster with API Gateway.

This post is contributed by Scott Horsfield – Sr. Specialist Solutions Architect, EC2 Spot Amazon EC2 Spot Instances are spare compute capacity in the AWS Cloud available to you at steep discounts compared to On-Demand Instance prices. The only difference between an On-Demand Instance and a Spot Instance is that a Spot Instance can be […]

Web and mobile applications usually interact with a backend service, often via an API. Many front-end applications pass requests for processing, wait for a result, and then display this to the user. This synchronous approach is only one way to handle messages, but modern applications have alternatives to provide a better user experience. There are […]

An Adafruit PyPortal displaying a quote while synthesizing and playing speech using Amazon Polly. As a natural means of communication, voice is a powerful way to humanize an experience. What if you could make anything talk? This guide walks through how to leverage the cloud to add voice to an off-the-shelf microcontroller. Use it to […]

Since the launch, we have seen a lot of interest from you, and have worked to bring additional features and services based on your feedback. In this blog series, […]

This blog post explores how you can solve geolocation queries using geohashing. I discuss how you should decide on the resolution of a geohash for your specific workload.

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 nine 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 […]

Serverless applications are event-driven, using ephemeral compute functions to integrate services and transform data. While AWS Lambda includes a 512-MB temporary file system for your code, this is an ephemeral scratch resource not intended for durable storage. Amazon EFS is a fully managed, elastic, shared file system designed to be consumed by other AWS services, […]
