Websites using Cloudflare services are faster, more secure, easier to manage

What is Cloudflare?

Cloudflare is one of the world’s largest networks. Today, businesses, non-profits, bloggers, and anyone with an Internet presence boast faster, more secure websites and apps thanks to Cloudflare.

Approximately 25 million Internet properties are on Cloudflare, and its network is growing by tens of thousands each day. Cloudflare powers Internet requests for ~16% of the Fortune 1,000 and serves 20 million HTTP requests per second on average.

Here’s how it works:

In the early days of the Internet, when you wanted to load a website, your request would go from your computer to a server, which would then return the web page you requested.

If too many requests came in at once, that server could be overwhelmed and crash, becoming unresponsive to anyone trying to access the resources it hosted.

This made it difficult for owners of Internet properties to provide content that was fast, safe, and reliable.

Cloudflare was created to ease these difficulties and empower users with the resources to make their sites, apps, and blogs safe and performant.

This is done through the use of a powerful edge network that provides content and other services as close to you as possible, so you get the information as fast as possible.

Einstein figured out some time ago that the speed of light is a hard upper limit on how fast you can communicate; there comes a point when the only thing you can do is move the content and computation closer! That’s why they put data centers in more than 200 cities all across the world: to give you what you’re looking for quickly!

Cloudflare also provides security by protecting Internet properties from malicious activity like DDoS attacks, malicious bots, and other nefarious intrusions.
It provides security and performance for approximately 25 million Internet properties and offer great functionality such as SSL and content distribution to every website on our network.

Cloudflare’s services run silently in the background, keeping many of the websites and services you depend on up and running.

What is DNS?

DNS stands for Domain Name System. It is something like the phonebook of Internet.

Humans understand words. Computers understand numbers.

When you type a web address on your browser or mobile (cell) phone, that is words.

There must be a middleware system that will trandslate that human readable address (URL) to an IP address understantable by computers, servers, routers, gateways.

That is the role of the DNS. It is a list that matches domain names with IP addresses numbers.

Actually it a little more complex than this preliminary explanation.

There is not a single phonebook for the whole Internet. There are many distributed phonebooks that each updates its others records. A process called DNS propagation that could last to up to 24 hours, when you make a change.

Now imagine that you have to change something in this “phonebook” about your business website.

Without Cloudflare, it could take up to 24 hours for changes to take effect. What ever that means about your visitors and your business emails…

With Cloudflare, the change is INSTANT.

What is CDN?

CDN stands for Content Delivery Network. It is a geographically distributed group of servers which work together to provide fast delivery of Internet content.

A CDN allows for the quick transfer of assets needed for loading Internet content including HTML pages, javascript files, stylesheets, images, and videos. The popularity of CDN services continues to grow, and today the majority of web traffic is served through CDNs, including traffic from major sites like Facebook, Netflix, and Amazon.

The benefits of using a CDN are:

  • Improving website load times – By distributing content closer to website visitors by using a nearby CDN server (among other optimizations), visitors experience faster page loading times. As visitors are more inclined to click away from a slow-loading site, a CDN can reduce bounce rates and increase the amount of time that people spend on the site. In other words, a faster a website means more visitors will stay and stick around longer.
  • Reducing bandwidth costs – Bandwidth consumption costs for website hosting is a primary expense for websites. Through caching and other optimizations, CDNs are able to reduce the amount of data an origin server must provide, thus reducing hosting costs for website owners.
  • Increasing content availability and redundancy  – Large amounts of traffic or hardware failures can interrupt normal website function. Thanks to their distributed nature, a CDN can handle more traffic and withstand hardware failure better than many origin servers.
  • Improving website security – A CDN may improve security by providing DDoS mitigation, improvements to security certificates, and other optimizations.
