A content delivery network (CDN) refers to a geographically distributed group of servers that 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.
It is not necessary that every website should use a CDN. For instance, if you are targeting visitors from a specific location or country only, you should prefer hosting your site on a server located as close to that desired location as possible. In this case, having a geolocated web host is better than having a geolocated CDN.
Why Is CDN Necessary for your Website?
If a user who lives in Nepal may visit a site that’s supported by a Sydney-based web host. If this website has a CDN somewhere close to Nepal, the user is granted access to the site from his or her edge server (the lowest server to his or her location) and the request no longer has to go all the way to Sydney to get a response. That is why CDN is necessary for your website. Here’s why we recommend CDN77:
Brotli Compression Algorithm
Every byte matters, especially when you pay for it. The most popular lossless compression utility Gzip has been around since 1992. The need for more modern algorithms emerged, which is why in 2016 CDN77 has become the first CDN provider to support Brotli.
Latest HTTP/2 Optimization
CDN77 boost your content delivery with the latest HTTP/2 features and improvements, for free and without any charges per HTTP(S) requests. CDN77 is the first CDN to support HTTP/2 back in 2015 and committed to keeping pace with the protocol development.
TLS 1.3 with 0-RTT
HTTPS is a must these days. And there’s a way to make it even faster and more secure. CDN77 supports the latest TLS 1.3 with 0-RTT to boost HTTPS performance and security all over the world.
Free SSL Certificate
Make your site HTTPS ready with their InstantSSL provided by Let’s Encrypt or install your own SNI certificate. Quickly, easily, for free. All HTTPS connections are powered up by the latest web performance and security features such as TLS 1.3 with 0-RTT or optimized HTTP/2.
CDN77 Offers All The SSL/TLS Options You Need:
- Instant unshared SSL for free: CDN77 provides you with an SSL Certificate using Let’s Encrypt authority for every CDN URL or CNAME added to your CDN Resource (cdn.your-website.com).
- Purchase SAN custom SSL: Get an “A” graded SSL Certificate from a certified SAN provider. Your and your users’ data will be 100% protected. With this level of security, your website is safe from threats such as Heartbleed and POODLE.
- Use your own certificate for free: Bring your existing SSL Certificate and install it on any CDN Resource for free. In the Control Panel, you’ll just need to copy & paste the SSL Certificate, intermediate certificates, and private key. CDN77 supports wildcard certificates as well.
Real-Time Attacks Detection And Block
Amplification DDoS attacks such as UDP Flood/NTP Amplifications are filtered by deny rules in the firewall on their edge router. TCP Syn Flood attacks are filtered through a custom-made filter, which consists of a fleet of custom servers located in each PoP and equipped with 100G+ network capacity.
Secure Tokens & Signed URL
Secure tokens allow you to generate secured links with an expiration time and/or lock them onto a specific IP address. CDN77 provides a unique token/password to generate signed URLs. You’re in full control over who can view your content.
IP & Geo Whitelisting / Blacklisting
When it comes to allowing or blocking specific users or countries, a simple deny/allow rule has you covered.
Hotlink Protection
Common content thefts will no longer be an issue. Lock your content for your domain only. Hotlink protection only allows requests with the correct referer header.
