Demand For a Faster Web
It is truly the epitome of the advent of information age when everyone from the tech savvy new age marketers to the way less tech savvy laymen stereotypes are seen on the streets tapping on smart phones, and talking rather enthusiastically and knowledgeably about dropping 3g internet rates. But it does not stop there, they want information and they want it now, on the go. People do not wait for your precious little website to load, they want it loaded and ready at the click of a button or the tap of a finger. To cater to the voraciously increasing demand for the huge reserves of information available through the internet in a fast and efficient way, an effective mode of content distribution called content delivery networks were designed and implemented.
