Nobody likes it when a website loads for what seems to be forever. In fact, most people would choose to close the page if it takes more than a few seconds to load. In order to avoid that, most websites implement what is a Content Delivery Network (CDN).
CDN is the invisible backbone of the internet that allows to speed up website’s loading time. It is essentially a number of data centers dispersed around the world that store a cached copy of a website’s content to shorten the physical distance that data has to travel. Imagine someone from Australia trying access your website, whose hosting server is located in New York. It would take a long time for the data to travel from its stored location before finally reaching the end user.
Twitter Bootstrap is a frontend framework, first developed by Mark Otto and Jacob Thornton at Twitter, and later on released as open-source in 2011. Usage of Bootstrap Framework for designing websites has rapidly increased in the last couple of years and continues to grow. According to the Builtwith.com, 20.4% of the most popular websites are built with Bootstrap, and it is especially trending in the Business domain.
While there are many readily available components, websites built with Bootstrap are as unique as their designers want them to be.
So let’s say a person visits a website that loads its JQuery libraries from MaxCDN. Then, when said person visits your website they already have the library saved in their browser’s cache and it won’t have to be downloaded again. Thus, it minimizes the loading time. This is one of the advantages of using public CDN.
