Maximizing ASP.NET Website Performance Using Cloudflare

What is Cloudflare?

In conclusion, Cloudflare is a content delivery network service. This article is a complete basic guide about Cloudflare as the leading CDN among web developers. You will get a clear understanding of what a CDN is, what Cloudflare is and what are its features and advantages.

Cloudflare can be said to be a superior CDN when compared to general CDNs. This is because Cloudflare is able to provide maximum service. Cloudflare itself has various packages, namely Pro, Business, and Enterprise.

But, what exactly is a CDN itself? CDN is a system that will provide content quickly to end users and this is in various data centers on the internet. The content distributed through this CDN is usually static content.

So, the way it works is by spreading web static content to several existing data centers. When static content is loaded from the web (js, images, css, video, and various other types of content) users will immediately receive content from the site. closest to the CDN, not via the web server.

In this case, Cloudflare’s advantage lies, because your website as a user can be loaded faster by end users wherever they are. Indeed, the CDN is actually not provided free of charge, but Cloudflare is willing to provide a free CDN for you with additional features.

This CDN is able to save Cloudflare bandwidth and spread it to all static content on the web, only then to distribute it back to all of CloudFlare’s data centers.

Cloudflare claims that there are more than 20 CloudFlare data centers spread across, especially in Southeast Asia, located in Singapore. CDN is highly favored by developers because it can save up to 50% bandwidth. So, the website can be 2X faster.

Cloudflare Features

Some of CloudFlare’s excellent features that you can take advantage of are:

1. Mirroring

The content on your site will later be mirrored to each Cloudflare data center. This is what causes your website as a user to be optimized faster when visitors are far from the main server.

2. Caching

This means Cloudflare runs caching functions at certain times and conditions. This one feature will save your hosting bandwidth, especially if web hosting has a limit on bandwidth. So, in simple terms, your connection will go both ways, namely to the web visitor and to the server.

3. Firewall 

This one feature can protect your website from security threats. In addition, you can block IPs from other countries, so you can determine which visitors can visit your website.

4. Analytics

This feature means monitoring all activities on your website. What activities are monitored? For example, the number of requests sent in the last 24 hours, the number of unique visitors, the origin of the visitors, and also the available bandwidth for a full 24 hours.

5. Railgun

This feature can also affect the speed of your website. Even Cloudflare with this feature claims that your website can increase its speed by up to 300%. However, this feature can only be used by users of the paid version.

Cloudflare Functions

After knowing the meaning and features, here are some important Cloudflare functions that are activated on the website:

  • Provide speed of access to website visitors
  • Monitor malicious traffic on the website
  • Improves website performance because it has proxy servers spread across several countries
  • Cloudflare can be used as a static content cache for websites, for example images, CSS, Javascript, and so on
  • Cloudflare can reduce server resource usage

Advantages of Cloudflare

Apart from having many features, the Cloudflare service also has various advantages, namely:

  • Cloudflare can hide the original IP address from your web hosting. What are the implications? Hackers get in trouble and can’t attack the servers they run.
  • Cloudflare also creates a web cache so resources to load the site can be faster and server load is reduced.
  • Cloudflare also provides optimal protection against all DDoS attacks by changing aspects of your web security.
  • If your site is down, CloudFlare claims to be committed to continuing to serve cached data until the site can be up again.
  • If the registrar doesn’t give us the option to add DNS records, we can use the nameservers from Cloudflare and add host DNS records there.
  • CloudFlare is a service that offers free features if we want to add multiple domains at once.
  • We can block site access from certain regions/countries. This setting may be what users want if at any time they get a lot of attacks from certain countries.

Finally, Cloudflare wants to provide free SSL for its users, which can also be used on shared hosts. You can also learn how to redirect http to https on our blog.

Toggle the button under Proxy status to enable or disable Cloudflare for particular subdomains. When finished, click Continue to move on to the next action.
