Why do websites need a CDN? The biggest reason why is to prevent websites from crashing when experiencing a large amount of traffic. David explains how CDNs help to balance the traffic load in the video below:
Here are some key takeaways from the video:
- High traffic websites need a CDN in order to scale. For example if you’re suddenly experiencing a large influx of traffic your website might crash. A CDN helps to balance the traffic.
- A CDN is made up of servers around the world that host your content, which it then serves to users from various locations.
- To give you an idea of how well equipped a CDN is to handle traffic, MaxCDN has hundreds of servers in 15 locations around the world.
- There are two types of customers that tend to require the services of a CDN. One type is enterprise customers, like TheNextWeb, and the second type is small bloggers.
- A CDN is very easy to implement, especially when using WordPress. There are plenty of plugins out there. like W3 Total Cache, that take only around five minutes to set up.
