serverless-patterns VS aws-cf-templates

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

I think any of the common proxy platforms would work, the example code just happens to be for HAProxy. Managing ECS isn't that hard once you get it stood up. https://github.com/widdix/aws-cf-templates widdix provides a ton of reference cloud formation templates that cover most aspects of running aws infrastructure. We run everything through cloud formation and it is self-scaling and self-healing. System manager can automate patch management as well.

Finally, if you’re feeling nostalgic for winter, this example from Symphonia is a lab for benchmarking Lambda cold starts for Java runtimes so that you can better understand how they behave and plan configurations accordingly.
