# Cloudflare Fundamentals

Cloudflare is one of the world's largest [connectivity cloud networks ↗](https://blog.cloudflare.com/welcome-to-connectivity-cloud). Today, anyone with an Internet presence can have faster and more secure websites and applications thanks to Cloudflare. This includes bloggers, businesses, and even non-profits.

Millions of Internet properties are on Cloudflare, and our network is growing by tens of thousands each day. Cloudflare powers Internet requests for millions of websites and serves 55 million HTTP requests per second on average.

Before you get started, we recommend reviewing [Concepts](https://developers.cloudflare.com/fundamentals/concepts/) to learn about key concepts related to using different Cloudflare products.
