You may not know what a Content Delivery Network is, but your online business can benefit greatly by using one. Imagine fast content-based delivery to the end-users who visit your web site from anywhere in the World. Typically, decreasing end-user load times is only achieved by having physical servers located in Data Centers strategically placed around the globe. CDN takes the place of physical servers and delivers content to your site visitors based on location. Quite simply, the closest proximity to the user determines what CDN node delivers the information to the site visitor. This would be quite costly if you needed to setup servers around the globe. Content Delivery Networks (CDN) drastically lower your cost and give you the same ability with minimal effort.
Wikipedia.com defines a Content Delivery network, or CDN for short as:
A content delivery network or content distribution network (CDN) is a system of computers networked together across the Internet that cooperate transparently to deliver content to end users, most often for the purpose of improving performance, scalability, and cost efficiency.
What kind of Content can be delivered?
Images, HTML, Flash files, MPEG, MP4, PDF’s and more can be delivered to your site visitors. Setting up a Content Delivery Network is much easier than you might expect. You can simply upload the images
What kind of Content can NOT be delivered?
Dynamic web site pages such as Database results. Databases and dynamic data must still be served from your Web Server.
Top 5 Reasons You Should Be A Using Content Delivery Network
Increased Bandwidth Delivery.
Sum of CDN Bandwidth is higher than the network backbone capacity. This results in an increase in the number of concurrent users. Imagine your network backbone only has 10 Gbit/s total capacity, any requests over 10 Gbit/s are lost or placed in waiting. Let’s pretend your using CDN and your web site has a DIGG effect for popular download or video hosted on your site. EXAMPLE: By using a CDN with 10 locations all utilizing 10Gbit/s backbone connections, you now have a total capacity of 10*10 Gbit/s.
Location, location, location.
The closer the content the faster the delivery. Site users will experience less network peaks and surges, and overall improved stream quality.
A CDN can offer 100% availability, even if your Data Center is offline. Even in times with power, network or hardware outages.
Considering the cost of setting up servers in 10 Data Centers around the World, a CDN offers an inexpensive way to accomplish the same goal. CDN gives you increased reliability and the ability to deliver HD quality content with high QoS, lowering costs and reducing network load. Not to mention, fewer internal resources.
Easy to Setup.
I personally tested CDN and can assure you that the interfaces are easy to use. Depending on the size of your content, you can be up and running in a matter of minutes.
Choose Your CDN Partner Wisely
Only a very few state-of-the-art Data Centers are currently offering CDN to their end-customers. If Web Site speed is important to your online business, you should only consider hosting in one of these facilities. Recommended CDN searching:
