Designing Event-Driven, Scalable Serverless Apps with AWS Services

This talk will dive deep into the world of serverless architecture and explore how AWS Services can be leveraged to build scalable and secure serverless applications. Using an event-driven architecture, I will show you how to design applications that respond to events in real-time, enabling rapid scaling to meet changing demands, while maintaining security and compliance.

We'll explore the benefits of using AWS Services like Lambda, EventBridge, Cognito, IAM, IoT Core, and Step Functions to create highly scalable and fault-tolerant serverless applications.

By the end of this talk, you'll have a deep understanding of how to build scalable and secure serverless applications with AWS Services and how to leverage event-driven architecture to create efficient, responsive, and cost-effective applications that are also secure and compliant.

3. About Me Software Engineer, Turing 5X AWS Certified AWS Serverless Community Builder Technical Writer Chibuike Nwachukwu
4. Agenda • Cloud Journey • Key Services • Example Architecture • Key Takeaways
5. Once you’re fully event-driven, you can be a lot more independent. Gwen Shapira, System architect at Confluent
6. Cloud Journey From then to now
7. From Monolith to Microservices, but still thinking in a tightly coupled way
8. Event-driven Architecture An event-driven architecture uses events to trigger and communicate between decoupled services and is common in modern applications built with microservices.
9. Benefits of Event-Driven Design • Loosely Coupled • Asynchronous Communication • Highly Scalable and Fault Tolerant • Improved User experience
10. Serverless Architecture It is a cloud-native development model that allows developers to build and run applications without having to manage servers.
11. Benefits of Serverless Design • No server management • PAYG (Pay as you go) model • Quick deployment • Highly Scalable and Fault Tolerant
12. Key Services
13. Amazon EventBridge For Event Choreography It is a serverless event bus that ingests data from your own apps, SaaS apps, and AWS services and routes that data to target.
14. AWS Lambda For Computing It is a serverless, event-driven compute service. In Lambda, you can define functions that run arbitrary code without having to provision any servers..
15. AWS Step Functions For Event Orchestration It is a serverless orchestration service that lets developers create and manage multi-step application workflows in the cloud
16. AWS IoT Core For Real-Time messaging It is a message broker supports devices and clients that use MQTT and MQTT over WSS protocols to publish and subscribe to messages.
17. AWS STS, Cognito, IAM For Access Control IAM: It is service for securely controlling access to AWS resources STS: It is a service that allows you to request temporary security credentials for your AWS resources, or IAM authenticated users.
