This repository contains modules use for the Serverless .NET Patterns presentations.

The Bitcoin.Topic module creates a Lambda function that publishes the most recent bitcoin price on an SNS topic. The SNS topic is exported from the CloudFormation stack so that other stacks can subscribe to it.

The Bitcoin.Table module creates a Lambda function that subscribes to the SNS topic from the BitcoinTopic stack and stores the received value in a DynamoDB table. Stored values are automatically forgotten after 15 minutes to minimize the number of stored rows. The DynamoDB table is exported for other stacks to query against.

The Bitcoin.Event module published the price from the SNS topic to the default EventBridge eventbus.
