Introduction to Serverless

Clarify the big picture of serverless and functions as a service in cloud computing. Experience a concise theory-to-practice format with a hands-on lab using open files.

Explore how serverless centers on event-driven computing and small, single-purpose functions that run on demand, with platform-managed infrastructure and benefits like agility, speed, and micro billing.

Write your function in any language, package it as a zip file or container image, and upload it to the serverless platform. A trigger runs it on demand.

Explore how the evolution of cloud shifts grunt work to managed services, enables bursty workloads with zero capacity planning, and showcases serverless pricing with CapEx-to-OpEx savings.

Explore stateless use cases for serverless functions that augment existing services, from image compression in blob stores to event-driven front-end and IoT workflows, while noting platform differences and future potential.

OpenFaaS basics present an open source service framework that packages code into containers for deployment on Kubernetes or Docker Swarm, enabling event-driven functions via HTTP endpoints.

Explore OpenFaaS continued, running any image or document as a function with a watchdog, using machine learning to identify content and monitor via Prometheus and the open source community.

Explore serverless, an event-driven model where you write code, package it, and run events with millisecond billing, lambda. Focus on delivering business value while no ops and scaling worries fade.
