That was kind of a misleading title, but I wanted to get your attention. The truth is that DynamoDB Streams have a maximum retention period of 24 hours and there is no way to extend that.

UPDATE: Ofcourse, after I finalized this article Amazon released native support for Private DNS on API Gateways. . Announced on the AWS Blog.
At PostNL we are building most of our applications with Serverless in mind, let me rephrase that, we build all our applications within our own landing zone …
Until recently, I was completely unaware of AWS CloudShell, and I’m glad I finally decided to give it a try. CloudShell provides a shell environment right in your browser, and to my surprise, you can start an instance within your own VPC!
Recently I’ve been working on a new project where we created many resources in a lot of different stacks. A feature of CloudFormation is that you can output values from your stack, which is great for referencing resources in other stacks. However, while there is a use-case for this, I’ve …
When working with AWS CDK and using SSM Parameters to store information in between stacks there are multiple ways to retrieve the value, with both advantages and disadvantages. In this post, I’ll go over the different ways to retrieve SSM parameters in AWS CDK and when to use them.
