Cloud computing is believed to have been invented by Joseph Carl Robnett Licklider while he was working as a computer scientist with the Advanced Research Projects Agency Network (ARPANET) in the 1960s. The cloud symbol was actually used as early as 1977 to represent networks of computers in the original ARPANET.
In the decades since its conception, cloud computing technology has advanced rapidly. In 1983, online service provider CompuServe offered its users a small amount of storage that could be used to store any file. In 1994, AT&T launch an entirely web-based platform for personal and business communications called PersonaLink Services. The term “cloud computing” was only popularized in 2006 when Amazon released its Elastic Compute Cloud product.
iCloud, which is arguably the most popular cloud storage platform in the world today, was launched by Apple Inc. on 2017. As of 2016, the service had almost 800 million users.
