Serverless Architecture Basics
Explore the fundamentals of serverless computing and how it can be leveraged to build scalable and cost-effective SaaS components.
Unpacking Serverless Computing
Serverless computing is an execution model where the cloud provider dynamically manages the allocation and provisioning of servers. You, as the developer, don't have to think about servers at all!
Instead, you write and deploy code, and the cloud provider runs it only when needed. This abstracts away the underlying infrastructure, letting you focus purely on your application logic.
Functions as a Service
The most common form of serverless computing is Function as a Service (FaaS). Here, you deploy individual functions that perform specific tasks.
- Each function is a small, independent piece of code.
- It runs in response to an event.
- It automatically scales from zero to thousands of instances.
Think of it as microservices taken to the extreme: nano-services!
