LinkedIn was created in 2003 to help users “connect to your network for better job opportunities.” By the end of their first week of operation, they had 2,700 members. One year later, they had over one million members, and have grown exponentially since then. By November 2015, LinkedIn had over 350 million members, who generate tens of thousands of requests per second, resulting in millions of queries per second on the LinkedIn back-end systems.
