Developing evolutionary architecture with AWS Lambda
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.
Implementing a LIFO task queue using AWS Lambda and Amazon DynamoDB
This post was written by Diggory Briercliffe, Senior IoT Architect. When implementing a task queue, you can use Amazon SQS standard or FIFO (First-In-First-Out) queue types. Both queue types give priority to tasks created earlier over tasks that are created later. However, there are use cases where you need a LIFO (Last-In-First-Out) queue. This post […]
Building well-architected serverless applications: Managing application security boundaries – part 2
This series 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 of the example application. Security question SEC2: How do […]
Monitoring and troubleshooting serverless data analytics applications
In this post, I show how the existing settings in the Alleycat application are not sufficient for handling the expected amount of traffic. I walk through the metrics visualizations for Kinesis Data Streams, Lambda, and DynamoDB to find which quotas should be increased.

Building leaderboard functionality with serverless data analytics
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.
Exploring serverless patterns for Amazon DynamoDB
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 […]
ICYMI: Serverless Q1 2021
All the feature launches, blogs, videos, tech talks and more happenings from the AWS Serverless service teams in Q1 2021.
Operating Lambda: Debugging configurations – Part 3
This post explains common integration errors in Lambda-based applications. These include running an unintended version or alias of a function, triggering infinite loops unintentionally, and issues with downstream availability. In each case, I explain steps you can take to remediate the issue.
Building an image searching solution with the AWS CDK
This post discusses a fully serverless architecture for searching images based on their contents. It shows how this architecture is decoupled and stateless by using S3 events, SQS messages, an EventBridge bus, and Amazon Aurora Serverless.
