Episode 16 — Understanding FaaS — Function as a Service and Event-Driven Design

In this episode, we focus on Function as a Service (FaaS), a serverless computing model that executes code in response to specific events. We explain how FaaS abstracts the underlying infrastructure, allowing developers to deploy small, discrete functions without managing servers or scaling policies. You’ll learn about the event-driven design pattern, triggers, and the integration of FaaS with services like storage events, HTTP requests, or scheduled tasks. We also discuss cost benefits from consumption-based billing and the agility this model offers for rapid feature deployment.We also explore the challenges of adopting FaaS, including cold start latency, state management, vendor lock-in risks, and security considerations such as permissions and runtime isolation. By the end, you’ll have a clear understanding of where FaaS fits in cloud architecture and how it might appear on the Cloud+ exam in both architectural design and troubleshooting scenarios.
