Back in the 1990s when the world was first introduced to the world-wide-web, no one thought it would last this long, much less that it would bring about a literal digital revolution in the life of everybody on this planet. Which is why, when you think of the fact that from people hosting their websites on their own inbuilt servers to going for paid hosting services, you realize how fast human technology has developed in the past few decades.
It has been noted that 50% pf the websites in the present times are hosted by either Apache or Nginx or even both of these open sources. With over 4.49 Billion webpages in the world today and over 999.99 Million websites, that does seem to be a daunting feat.
