Declarative vs programmatic IaC

What’s the difference between declarative and programmatic approaches to Infrastructure as Code? Why does it matter, and when should you choose each approach?

Explore best practices for writing maintainable, scalable Infrastructure as Code across AWS CloudFormation, AWS SAM, AWS CDK, Pulumi, Terraform, SST, and Serverless Framework. Learn how to leverage the strengths of each approach while avoiding common pitfalls.

In a short code walkthrough, you’ll see the power of AWS CDK constructs and patterns in action, showcasing how programmatic IaC can simplify complex infrastructure scenarios.

Slideshow + live demo + Q&A

Colorful quantum randomness

Experience the power of quantum superposition through this visual hands-on demo to generate truly random colors using actual quantum computers available on Amazon Braket.

See how quantum randomness can supercharge real-world applications in cryptography, material science simulation, and optimization problems that classical computers struggle to solve efficiently.

Showcase of quantum algorithm development using OpenQASM and Qiskit frameworks, running on IBM Quantum and Amazon Braket platforms. No prior quantum physics knowledge required, just bring your curiosity for emerging technologies!

From serverless to functionless

What if you could build your next serverless application without a single Lambda function? Let me introduce you to the functionless model: a serverless architecture that emphasizes event-driven, service-based design by connecting AWS services directly, eliminating the need to package, deploy, and manage countless individual Lambda functions.

In this demo, you’ll see a functionless application in action, built with AWS CDK. Instead of writing custom code in intermediary Lambda functions, the application uses direct integrations between AppSync, Step Functions, EventBridge, and DynamoDB to handle all business logic and data flow.

This is "Super Mario Post": Mario sends love letters (events) to Princess Peach. She collects them, enriches them with her reactions (emojis), and stores them in a secret drawer (global table). Everything happens within the same Mushroom Kingdom (an AWS account), spanning both Rock & Cloud Worlds (AWS regions).

You’ll walk away understanding how to reduce operational complexity, improve performance, and lower costs by leveraging native AWS service integrations. All while building more maintainable serverless architectures, and having a bit of fun in the process.

Build a self-service for your tenant AWS accounts

How to use AWS Service Catalog to build catalogs of products (CloudFormation templates) and to distribute them to end-users? Create portfolio based on library of ready to use products, deploy own products with AWS CDK, share portfolios with AWS Organisations, integrate AWS Service Catalog with ServiceNow.

Policy as Code with AWS CDK and GitHub Actions

As infrastructure moves faster with Infrastructure as Code and continuous delivery, securing cloud environments can't be just an add-on.

Explore how to embed Policy as Code into your CI/CD pipelines using AWS CDK and GitHub Actions. Ensure that security and compliance are automated from the start.

Level up your DevSecOps game with some actionable insights to help you build secure AWS infrastructures by default.

Preferred session duration: 30-45 mins

Infra as Vibe Code with AWS MCP Servers

What if you could “vibe code” your serverless solutions on AWS using dedicated MCP Servers? Just give AI agents access to your AWS accounts. What could possibly go wrong?

Discover how to combine Amazon Q, AWS CDK, and AWS MCP Servers to rapidly develop serverless architectures through natural language prompts, and how to do it in a controlled, secure manner.

In this live demo, you’ll see a complete functionless application generated from scratch using Q Developer CLI and AWS MCP Servers for CDK, Step Functions, and DynamoDB.

Understand how AI-assisted infrastructure development can accelerate your workflow, reduce boilerplate code, and make cloud architecture more accessible. Learn when to trust the agent and when to double-check its work.
