What is Cloudflare? And What are the benefits of using Cloudflare?

By on May 16th, 2022

The internet is a place where you can find anything. We have websites, blogs and web tools that can do any task or provide any required information. For example, you want to buy any materialistic things like clothes, electronics or food. You can get it in a couple of hours at your doorsteps. Here, we can find millions of small, medium and large businesses connected to the internet. Big companies have their security equipment or are secured privately. And small and medium businesses and other non-tech humans have a limit with the security policies. So, Cloudflare provides security and performance to small and medium-sized businesses and web assets like Websites, Applications or any device connected to the internet.

In short, CloudFlare is an infrastructure provider of the internet. And the ideal behind Cloudflare is to provide reliability, extra security and performance to devices connected to the web. It provides some core features for free and the simplest setup for installation. With GUI and API interfaces to manage your website, Cloudflare is the largest network. It offers most of the key features for free with limited usability, but it also has premium memberships for extra features.

Working of Cloudflare

As per the technical perception, CloudFlare works like a Reverse Proxy server. That means your website traffic will be routed by Cloudflare servers, spread in more than 200 cities worldwide. In simple words, each request will be attended by Cloudflare before it reaches our website. Cloudflare adds more performance and security for both sides of people, like owners and visitors. Cloudflare checks each request and scans for any malicious content based on the IP Address information. It also has other types of information checks like Resource request, Request payload and frequency and the user-defined firewall rules.

All the Cloudflare servers, also known as “Edges”, will cache the web pages and content and then serve it to the visitor. Here edges will become your CDN(Content Delivery Network), so the visitors must touch the Edge before reaching the original website. And with the dynamic web pages, CloudFlare will send each request to the original web server.

Features of Cloudflare

  • Stable Content Caching

Cloudflare servers or edges cache the web pages for faster delivery which is also beneficial in reducing latency issues.

  • Alleviate DDoS Attack 

DDoS attack stands for denial-of-service, which means these attacks will temporarily disrepute the host’s services. So the visitor can’t reach or sees the error of server unavailable. Cloudflare provides complete protection against DDoS attacks. On average, Cloudflare blocks more than 57 million threats per day to be secured.

  • Location-Based Routing

Cloudflare uses Geo-based routing to serve the content super fast and balance server loads. It means the request will be responded to by the nearest server of the device location.

  • Argo Tunnel

Cloudflare allows you to create a safe tunnel between the DataCenters and Hosting servers. You can build a secure transfer tunnel to ensure secure communications.

  • Mobile Optimization

Cloudflare uses some virtualisation to detect the type of devices that have been used to send the request. Then Cloudflare optimises the performance for the devices with lazy load images and browser cache, and the whole process is working on auto-mode.

  • Streaming Platform

Cloudflare also provides a demand-streaming platform that is economical and ready to use. 

  • Analytics

Cloudflare also offers insights and intelligence with the help of cache data. It also allows different dashboards, which can be personalised using GraphQL and Analytics API.

  • Identify New Threats

Cloudflare servers contain intelligence systems to learn every attack attempt on your website. So, next time they can provide instant solutions for other websites based on recorded experience.

  • Big Network

Cloudflare is one of the most truly connected networks using strategic partnerships in China. It delivers fast, secure, and reliable experiences globally for the user’s device.

  • CDN with Load Management

Cloudflare has a Great load management strategy with more than 200 centres globally. As we discussed, it redirects the request to the nearest server to balance the traffic load.
