Cloud Functions & Serverless WASM

Serverless computing is a cloud execution model where the cloud provider dynamically manages the allocation and provisioning of servers. You only pay for the resources consumed when your code runs.

Cloud functions (or Functions-as-a-Service, FaaS) are the core of serverless. They are small, event-driven pieces of code that execute in response to triggers like HTTP requests, database changes, or file uploads.

While powerful, traditional cloud functions often face challenges:

• Cold Starts: The delay experienced when a function is invoked after a period of inactivity, as the runtime environment needs to spin up.
• Vendor Lock-in: Functions are often tied to specific cloud provider runtimes (e.g., AWS Lambda, Azure Functions), making migration difficult.
• Runtime Size: Some language runtimes (like Node.js or Python) can be relatively large, impacting startup time and resource usage.
