AWS NYC Summit 2023 Talk: Scaling Event-Driven Architectures with Serverless Micropayments (DevChat)

AWSServerlessInfrastructure as Code
Written By Brian H. Hough

At the AWS NYC Summit 2023, I delivered a 30 minute DevChat to ~200 attendees on how I built an event-driven serverless micropayments system on Amazon Web Services (AWS) for The Capital Platform.

In my talk, I discuss:

⚖️ Cases for serverless vs. serverful architectures

🤖 How I used LLMs (OpenAI, Google Bard, and Hugging Face) while building

🗺️ How I built our serverless payments architectures with Stripe and many AWS services

🗃️ What our multi-table database design looks like with DynamoDB


Serverless is more than "just Lambda," and this approach, combined with our Infrastructure as Code (Iac) pipeline, has allowed us to stand up features, front-end-to-back-end, with robust autoscaling and updatable configurations, like payments.


ABSTRACT:

Waiting 2–5 business days for a payment to process, and even longer for it to get delivered? That’s so 2003. In this dev chat, learn how experts wanted to re-engineer the concept of peer-to-peer (P2P) payments between users to prioritize speed, security, and accessibility. According to LinkTree’s 2022 Creator Report, of 4.2B social media users, roughly ~200M are creators. Yet 53% of these creators earn less than or equal to $100. Join this dev chat to discover the why behind creating serverless microservices and how decoupling a complex workflow on AWS let engineers scale this major financial service for users.
