Cloudflare

IN PROGRESS

Content is being prepared...

Cloudflare is a global security and performance network that helps increase the speed and security of websites and services by providing a distributed network of servers that optimize content and filter malicious traffic. It is often used for protection against DDoS attacks, securing user data, and reducing page load times thanks to an extensive CDN.

Cloudflare offers a wide range of services, and their number grows over time. Here I will mention just a few that are very important to me.

Cloudflare Account

To set up Cloudflare services, we will first need a Cloudflare account. Creating one is very simple:

• Go to the Cloudflare website.

• Fill in your email and password.

  

Cloudflare Websites

DNS Services

Cloudflare Proxy (Orange Cloud)

• Part of DNS services - allows managing domain DNS records through Cloudflare.

• A reverse proxy server that stands between the user and the hosting server, hiding the actual IP address of the server and providing an additional layer of security.

• Optimizes speed and security by routing all traffic through the Cloudflare infrastructure.

  

info

If the DNS record is set to proxy through Cloudflare, then only HTTP/HTTPS traffic will work, and everything else will be blocked, including, for example, SSH.

Cloudflare Zero Trust

Cloudflare Tunnel

• Securely tunnels traffic from the web server to the Cloudflare network without the need to open publicly accessible ports.
• Ensures secure access to applications without publicly accessible IP addresses.
