There are several ways to perform espionage activities in the life of a serverless app, which all battle for your attention. Time for the advent of counterintelligence: We want answers! - And CDK/Source examples of how to use it! Here we go, Serverless spy vs spy in four chapters, each post published after you light the next candle.
You like Lambda testevents? Great! But with “automate everything”, manual console clicks are considered dirty! Keep your hand clean by automating the creation of Lambda test events. So you can give your team, and yourself prepopulated test events. This example shows you the terraform code - because this is the fastest way. With a little effort, you can translate it to CloudFormation or AWS-CDK!
In this blog, I take you along on my journey to build my first Golang-based Lambda function. Inspired by surprise on my RDS bill, I built a Lambda function in Go to periodically stop running databases with a specific tag. Come, learn and debug with me!
Lambda destinations enable you to respond to successful or failed asynchronous invocations in a way that wasn’t possible before the feature was added. I explain what this feature allows you to do and show you how to use it.
You have probably seen architectures that use DynamoDB streams to perform change data capture on tables and Lambda functions to process those changes before. Today, we’ll do a deep dive into the underlying technology and explore how we can configure and tweak this configuration to our advantage.
Last week in the AWS slack developer channel once again, somebody was asking: “How can I run a Lambda locally?”. Well, that is a valid question, but there is a chance that you only think you need a local Lambda emulator because you do Lambda Spaghetti! Spaghetti code is a phrase for unstructured and difficult-to-maintain source code. I show you an easier way to test Lambdas locally and have some arguments that a local Lambda runtime should only be the very last resort. On top, you get examples in Pasta-Python, Gemelli-Go and Tortellini-Typescript.
In this post I’ll show you how to trigger your Lambda functions in intervals smaller than a minute using StepFunctions and the CDK.
Lambda Event filters are a great addition to our serverless toolbox and allow us to both simplify our code as well as save money. That’s great, but they can also delete messages from your SQS-queues if you’re note careful. In this post I’m going to show you what to watch out for.
