Serverless Computing Foundations: FaaS and CaaS

Cloud computing is rapidly shifting away from managing physical servers, but choosing the right modern architecture can be overwhelming. Understanding the distinct categories of serverless technology is the key to building efficient, resilient applications. This text-based course guides you through the fundamental concepts of serverless computing, focusing on Functions as a Service (FaaS) and Containers as a Service (CaaS). You will gain the clarity needed to evaluate, choose, and design the right serverless model for your specific project needs. Learn to: Understand the foundational principles of serverless computing, including automatic scaling and pay-per-use billing models; Compare the core differences, advantages, and trade-offs between FaaS and CaaS; Analyze deployment aspects, execution lifecycles, and how to mitigate common issues like cold starts; Explore modern observability patterns, logging, and monitoring strategies for distributed serverless applications; Evaluate real-world use cases to determine when to use micro-functions versus containerized services. You will start with essential cloud terminology before diving into architectural patterns, security baselines, and deployment configurations. Through clear written explanations and conceptual scenarios, you will build a solid practical foundation. This course is designed for software developers, system administrators, and cloud beginners who want to grasp serverless concepts without needing prior infrastructure management experience.
