Online retailer Flipkart is now following global pioneers like Amazon and Google to build its own servers and networks. The move is aimed at creating a platform that responds to specific requirements. The decision to build its own servers follows painful experiences of the past. Flipkart’s first Big Billion Day sale, in 2014, was a big turning point for the company, which was able to cross $1 billion for the first time since inception. But it was also a major embarrassment for the e-commerce giant.
