This is intended to be a repo containing all of the official AWS Serverless architecture patterns built with CDK for developers to use.
Follow @CdkPatterns for live discussion / new pattern announcements. I plan to add a new pattern weekly so check back regularly!
Note, this is maintained by @nideveloper not AWS. For my motivation, please read this blog post

Pattern Usage
All patterns are available in Typescript and Python so pick your favourite language! Note the Typescript patterns all include unit tests but right now I have not seen a standard python testing approach
You can always clone this repo which contains every pattern in python/typescript but if you just want a single pattern in one language follow these steps:
1) Choose your pattern
Browse the "Grouped Alphabetically" patterns list below or run:
npx cdkp list
2) Download Pattern In Python or Typescript CDK
TypeScript
All Patterns support the same commands so you can just run:
npx cdkp init {pattern-name}
cd {pattern-name}
npm run test
# requires you to be using cloud9 or have ran aws configure to setup your local credentials
npm run deploy
Python
The CDK CLI is still installed via npm so make sure you have the latest version of node installed or the npx commands will fail. Then you can just run:
npx cdkp init {pattern-name} --lang=python
cd {pattern-name}
# create a virtual env and install your dependencies
python -m venv .env
source .env/bin/activate
pip install -r requirements.txt
# test everything is working by outputting the cloudformation
npx cdk synth
# requires you to be using cloud9 or have ran aws configure to setup your local credentials
npx cdk deploy

Single Page Application S3 Website Deploy
These are built using https://www.npmjs.com/package/cdk-spa-deploy and allow you to deploy a website in as little as 5 lines of CDK code.
The Big Fan
You can integrate API Gateway directly with SNS and then add some resiliency by integrating your event consumers via sqs and message filtering.
The Destined Lambda
This is a stock implementation of Lambda Destinations with Amazon EventBridge
You can decouple your event driven architectures with EventBridge rules and now you can strip the custom EventBridge code from your Lambda functions with Lambda Destinations.
The Dynamo Streamer
This was taken from this Tweet
You can integrate API Gateway directly with DynamoDB and that way your systems can be more resilient! "Code is a liability" so less lambda functions, less liability
The EventBridge ATM
This was taken from this Blogpost
You can easily create routing rules in EventBridge to send the same event to multiple sources based on conditions. This example shows you how
The EventBridge Circuit Breaker
Integrate with unreliable external services? Build a circuit breaker and handle the risk
The EventBridge ETL
Build a fully serverless CSV to DynamoDB pipeline
The Scalable Webhook
Need to integrate a non serverless resource like RDS with a serverless one like Lambda? This is your pattern
The Simple GraphQL Service
Simple graphQL service built with AppSync
The Simple Webservice
The most basic pattern on cdkpatterns, the start of most peoples serverless journey
The State Machine
Have complex orchestration logic in your application? Build a state machine

The EventBridge ETL
Resiliency Focused Patterns
The Big Fan

The Destined Lambda
This is a stock implementation of Lambda Destinations with Amazon EventBridge
You can decouple your event driven architectures with EventBridge rules and now you can strip the custom EventBridge code from your Lambda functions with Lambda Destinations. This is resiliency focused because the failure events include the full event that triggered the lambda to fail, meaning you can craft retry logic or do manual investigations from a DLQ.
