Introduction

Cloudflare is a global CDN (Content Delivery Network) and a web security provider, providing performance, security and reliability. CloudFlare’s edge network spans over 100 points of presence around the world with more than 15 data centers as well as 150 PoPs.

What Is CloudFlare?

Cloudflare is a content delivery network (CDN), web security provider, DNS provider, web performance and optimization provider and domain registrar. They offer services that can be used with any website in the world.

How CloudFlare works.

CloudFlare’s global network of data centers provides a distributed, high availability system that accelerates performance for your website. The edge network consists of servers located closest to the users you want to protect, who then pass along any requests through CloudFlare’s DNS-based caching service (which has been called “the world’s fastest CDN”).

Cloudflare reverse proxy also caches content from your origin server so it can be served more quickly than if you were using traditional methods like Apache or Nginx.

What Does CloudFlare Do?

CloudFlare, a content delivery network (CDN) and distributed domain name system (DNS), is a company that you can use to speed up your website’s performance.

CDN is an acronym for “content delivery network”, which is a service that helps make your site load faster by serving its files from multiple locations worldwide. This allows your visitors to enjoy faster loading speeds and decrease the traffic on your server.

In addition to speeding up websites, CloudFlare also offers free protection against DDOS attacks with their Web Application Firewall (WAF). The WAF protects against brute force attacks and SQL injections by blocking suspicious requests before they reach your server or databases.

Web Security

CloudFlare’s Web Application Firewall (WAF) protects you from a wide range of attacks, including SQL injection and cross-site scripting (XSS) attacks.

  • SQL Injection: An attacker injects SQL queries into input fields on your site that are not properly sanitized. These queries are executed against your database and can be used to view or modify data in your database.
  • Cross-Site Scripting: Malicious JavaScript is injected into user interfaces of websites via HTML comments, hidden fields, or other techniques. This allows attackers to bypass browser security policies in order to send malicious code to the client machine when visiting infected sites.

Performance

CloudFlare is a content delivery network (CDN) that accelerates and protects websites. It’s super easy to use, has no downtime, and can be deployed in minutes. CloudFlare is used by businesses of all sizes around the world—including by major companies like Kickstarter and National Geographic—and it’s free for personal sites too. CloudFlare works by sitting between your site visitors and your hosting provider, so when someone visits your site, their request travels through CloudFlare instead of directly to you. This process improves performance because it means that fewer resources need to be used on each request since they’re handled by a centralized server rather than thousands of individual ones scattered around the world.

Reliability

CloudFlare is a global network of data centers, a CDN and DNS provider, WAF, SSL, DDOS protection and firewall. The company combines these services together to offer customers one complete package that makes their website faster and more secure.
