Category: AWS Serverless Application Model

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. Security question SEC2: […]

Amazon DynamoDB is a fully managed, serverless NoSQL database. In this post, you learn about the different DynamoDB patterns used in serverless applications, and use the recently launched Serverless Patterns Collection to configure DynamoDB as an event source for AWS Lambda. Benefits of using DynamoDB as a serverless developer DynamoDB is a serverless service that automatically […]

In this post, I explain the all-time leaderboard logic in the Alleycat application. This is an asynchronous, eventually consistent process that checks batching of incoming records for new personal records. This uses Kinesis Data Firehose to provide a zero-administration way to deliver and process large batches of records continuously.

This is part 5 of the Getting started with serverless series. In part 4, you learn how the developer workflow for building serverless applications differs to a traditional developer workflow. You see how to test business logic locally before deploying to an AWS account. In this post, you learn how to secure and manage access […]

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 blog is part 4 of the “Getting started with serverless for developers” series, helping developers start building serverless applications from their IDE. Many “getting started” guides demonstrate how to build serverless applications from within the AWS Management Console. However, most developers spend the majority of their time building from within their local integrated development […]

In this post, I introduce the Alleycat racing application for processing streaming data. I explain the virtual racing logic and provide an overview of the application architecture. I summarize the deployment process for the different parts of the solution and show how to test the frontend once the deployment is complete.

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 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 […]
