Cloudflare: what is it and it works?

Cloudflare is a leading internet security and performance company that provides a range of services to help keep websites and online applications secure and running smoothly. Founded in 2009, Cloudflare has since become a household name in the tech industry, with over 200 million websites and applications relying on its services.

How Cloudflare works ?

Cloudflare works by sitting between a website or online application and its end users. When a user tries to access a website or application that is protected by Cloudflare, their request is routed through Cloudflare’s network of data centers.

The data centers analyze the incoming traffic and apply various security and performance-enhancing measures to it. For example, Cloudflare’s web application firewall (WAF) will check for any suspicious activity, such as a potential cyber attack, and block it if necessary. Cloudflare’s content delivery network (CDN) will also optimize the delivery of static content, such as images and videos, to improve the overall performance of the website or application.

Once the traffic has passed through Cloudflare’s network of data centers, it is then sent to the website or application’s origin server. The origin server processes the request and sends the response back to Cloudflare, which then delivers it to the end user.

Overall, Cloudflare’s network of data centers acts as a buffer between a website or application and its users, helping to keep the website or application secure and running smoothly.
