This post examines how cold starts impact performance in serverless backends for web applications. It shows how the most important focus area is usually synchronous APIs called by the frontend application. I explain options available for targeting cold starts in the Lambda service.

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.

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 […]

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, […]

EventBridge is the evolution of the CloudWatch Events service. It brings new features, including the ability to integrate data from popular SaaS providers as events within AWS.

This blog post provides recommendations for designing and managing code repositories in larger serverless projects, and best practices for deploying releases of production systems.

This post is contributed by Isaac Vallhonrat, Sr. EC2 Spot Specialist SA Amazon EC2 Spot Instances allow customers to save up to 90% compared to On-Demand pricing by leveraging spare EC2 capacity. Spot Instances are a perfect fit for fault tolerant workloads that are flexible to run on multiple instance types such as batch jobs, […]

The standard S3 to Lambda integration enables developers to deploy code that responds to bucket- or object-based events. Using Amazon EventBridge, you can employ even more sophisticated routing and filtering of events between S3 and Lambda.

This blog post shows how you can use an event-based architecture to decouple services and functional areas of applications. It uses the document repository solution as an example, to compare architecture after shifting to an event-based approach.
