serverless VS aws-cdk-examples

I don't know any tutorials that cover all of these, but check out: https://cdkpatterns.com/ for 1) https://docs.aws.amazon.com/cdk/v2/guide/cdk_pipeline.html for 2) 3) and 5) https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-cdk-testing.html for 4)

I would like to see re-useable design patterns advocated similar to the terraform/terragrunt modules concepts. Encouraging pulumi.ComponentResource definitions multi environment structure, best practices. The cdk guys have something similar https://cdkpatterns.com/.

While writing this post, the four stacks combined are 129 lines of source code. With the help of the CDK Constructs that are being used this translates to over 1k lines of code in CloudFormation. We are only using L2 constructs here – there is way more constructs available that you can use in the Constructs Hub and also a lot of guidance regarding the usage of CDK over at CDKPatterns.

I use the "Lambda-lith" pattern, primarily because I am using Rust and deploying via CI/CD (codepipeline).

Here is a read of common lambda design pattern https://github.com/cdk-patterns/serverless/blob/main/the-lambda-trilogy/README.md

Level 3 constructs are opinionated units of reusable code which often deliver a service. Open source level 3 constructs are available from AWS Solutions Constructs - an extension to the CDK, CDK Patterns - a library of well-architected patterns, Construct Hub - a library of open-source constructs and some even come out of the box with the CDK - these are appended with 'patterns' to make them identifiable. Two examples are shown below:

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
