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. Reliability question REL1: […]

This post looks at implementing common relational database patterns using DynamoDB. Instead of using multiple tables, the single-table design pattern can use adjacency lists to provide many-to-many relational functionality.

In November of 2019, we announced AWS Lambda function state attributes, a capability to track the current “state” of a function throughout its lifecycle. Since launch, states have been used in two primary use-cases. First, to move the blocking setup of VPC resources out of the path of function invocation. Second, to allow the Lambda […]

In this post, I introduce some of the core streaming concepts for serverless applications. I explain some of the benefits of streaming architectures and how Kinesis works with producers and consumers. I compare different ways to ingest data, how streams are composed of shards, and how partition keys determine which shard is used. Finally, I explain the payload formats at the different stages of a streaming workload, how message ordering works with shards, and why idempotency is important to handle.

This post was written by Ahmed ElHaw, Sr. Solutions Architect Using AWS Direct Connect or AWS Site-to-Site VPN, customers can establish a private virtual interface from their on-premises network directly to their Amazon Virtual Private Cloud (VPC). Hybrid networking enables customers to benefit from the scalability, elasticity, and ease of use of AWS services while […]

This post was written by Ashish Mehra, Sr. Solutions Architect and Ramesh Chidirala, Solutions Architect Many customers design their applications to use Amazon API Gateway as the front door and load test their API endpoints before deploying to production. Customers want to simulate the actual usage scenario, including authentication and authorization. The load test ensures […]

This post shows how you can evolve a workload using hexagonal architecture. It explains how to add new functionality, change underlying infrastructure, or port the code base between different compute solutions. The main characteristics enabling this are loose coupling and strong encapsulation.
