serverless-patterns VS aws-cdk-examples

You may be aware of Serverlessland, a treasure trove of developer-centered content and examples of serverless applications. I decided to take one of their more popular (and AI-focused) tutorials, titled “Use GenAI capabilities to build a chatbot”, and recreate it with App Composer and our trusty AI assistant. Here we go!

Serverless Land is a place with a ton of serverless resources.

If you're looking for examples, you can check out my GitHub, it's full of SAM templates that cover a wide range of use cases. Serverless Land is another fantastic resource full of reference material. If you are trying to build something but can't quite figure it out in SAM, remember - it's all just CloudFormation. Browse the docs to see how to define that stubborn resource.

I will use dynamodb-streams-to-eventbridge-outbox-pattern by David Boyne as an example.

This is definitely not the most common pattern. As an independent data point, you can look at the AWS-maintained serverlessland.com, where ALL the patterns that include SNS and SQS are going SNS > SQS.

For all my associated exams I used Mareek/TD, labs and for SAP also went through SAP course of A. Cantrill, also tools like https://serverlessland.com/ and aws event talks on YouTube can help you understand concepts.

For serverless, serverlessland.com

If you’re using AWS serverlessland is maintained by AWS and has great resources

If you are in aws, look at CDK there are modules that make this pretty easy https://github.com/aws-samples/aws-cdk-examples/blob/master/typescript/lambda-cron/index.ts

I am not sure where to post my CDK question. I am trying this project specifically https://github.com/aws-samples/aws-cdk-examples/tree/master/python/existing-vpc-new-ec2-ebs-userdata

There are a ton of other example projects here for the AWS Cloud Development Kit: https://github.com/aws-samples/aws-cdk-examples Hope this helps, happy coding!

I am looking at examples of the CDK in python for example https://github.com/aws-samples/aws-cdk-examples/blob/master/python/ec2/instance/app.py

The cdk exple repo is also invaluable. I prefer cdk to terraform because it's actual infrastructure as Code as opposed to templating language as Code. There is fear of vendor lock. But I saw a while back that even hashicorp is working on a cdk implementation

For example, an AWS CDK that describes an infrastructure might look like this: https://github.com/aws-samples/aws-cdk-examples/tree/master/typescript/api-cors-lambda-crud-dynamodb
