Today speed is everything. If you have website visitors and customers spread across the globe, the physical distance of client from server creates havoc due to network bottlenecks, even though your hosting server is screamingly fast! Net result only 10-30% of your website viewers experience the intended website performance.
So what do we do??? If we move web-server to an alternate part of the world, other geographical customers face the same issues. Ideally we need multiple geographically locale web-servers, serving the same content to clients physically closest to them. But then how would we sync the data across multiple servers; what about databases!; and finally let say 10 servers for one website, the cost would go through the roof!
This is where Content Delivery Network (CDN) comes in. It is a network of web-servers spread geographically that sync data from the origin server (starting server or main server) and serve content to customers located closest to them. CDN are optimised for serving static website content such as pictures, css files, javascript files, media files and digital downloads. This ensures that the origin server still hosts the dynamic databases, ensuring data integrity. This drastically improves website performance for 90% of the global visitors.
At Indic Hosts, we have partnered with global top-level content delivery service leader, with edge-servers in 70 countries to provide to an economical world-class solution.
Sometimes we need to actually see it to believe it. To see a CDN in action click here. Note how the server IP Address changes as the ping location changes geographically. Note the "avg. rrt" time for your city.
Now see how a file is called in normal hosting, click here. Note the IP Address remains same across the globe and how the "avg. rrt" times vary geographically.
