Home Computers and The Internet
Another technological breakthrough , the micro-processor in the early 70ties (the first commercially available micr0-process was the 4004 from Intel) changed the computer industrie in a way it never happened before. The Altair 8800 was a micro-computer construction set for around 500$ that laid the ground for computer pioneers in the USA and a democratization of access to computers. The first operating system CP/M and programming languages like BASIC created a thriving eco-system around micro-computers with applications outside the classical enterprise domain like gaming, music and graphics, learning vocabulary or maths. The computer found its way into the home – and becomes smaller, more powerful, better graphics: Apple 2, PET 2001, ZX81/Commodore 64, MacIntosh, and of course the triumph of the PC and Microsoft that somehow inherited the PC monopoly from IBM. In the entreprise, we see the raise of Mini-Computers and DEC – also for researches and smaller enterprises – that died with the raise of the PC.
Already In the 70s, computer started to be connected (remember the ARPANET project) and laid the basis for the Internet and the World Wide Web that began to conquer the world in the 90 of the last century. The first web-applications (E-Commerce, what else?) started to pop-up in the mid 90ies. Given the today definitions of cloud computing and its different flavors IaaS, PaaS, and SaaS, web-applications were the first form of cloud computing. Amazon’s web-shop, Yahoo’s directory service, Google’s search engine, Flickr’s photo sharing site, WordPress’ blogging-tool, Google’s Gmail and Docs are milestones in the history of web-applications – and what we call SaaS today. In 2006, Amazon launched S3 and EC2, services that allow to allocate computing ressources – storage and virtual servers – via the web. That means, not only applications, but complete data-centers can run somewhere else in the world. The term cloud computing was born – motivated by the little clouds used in network diagrams to describe a network like the Internet transparently.
