'The world only needs 5 computers'

That statement of IBM president Thomas J. Watson was once considered a bullshit. But recently, Sun Microsystems technical director Greg Papadopoulos confirmed that we only need 5 to 7 computers . huge.

They include Google, eBay, Amazone.com, Salesforce.com, Yahoo, Microsoft and a system that Papadopoulos calls "Great Computer of China".

" Most people think 'computer' means a single PC or server, and I, like others, consider computers a network, such as eBay with the integration of more than 8,000 PCs, " explains Papadopoulos. " Google's network contains thousands of processors, millions of drives, archives and other link elements, but it's still a computer ."

To build these "computers", the world will exist only a few major suppliers, like Airbus and Boeing in the airline industry. Also according to Papadopoulos, Salesforce and Google are adding thousands of servers each year and their scale of operation is expanding at a dizzying pace. On average, Google can absolutely give each user a few GB of storage and leisurely collect money from online advertising.

Therefore, future software will be distributed as a service (SaaS). Users do not purchase products that they purchase services related to that product.

" This is being done by small and medium enterprises in the past. The world will spend about 2.5 to 3 trillion USD for information and communication technology but not for equipment procurement. which is for software and services , "concluded Papadopoulos.
