But don't get me wrong, as far as I can tell, Google's hardware and data center facilities are the best in the world, and other companies are still nowhere near as good as Google. But the software behind these hardware is already 10 years old, and the software was developed primarily to build search engines and crawler technology, and these technologies are clearly obsolete today. ”

"Compared to new technologies like Messagepack, JSON and Hadoop, Google's Kyoto buffers, bigtable, and MapReduce technologies are already part of the dinosaur-level software," Prassana said. And new projects such as Google GWT, closure and Megastore are moving too slowly. ”

The Sai points out that Facebook is the user of Hadoop's Open-source technology. Facebook recently opened its first data center and published the data center's technical parameters in open Source license form. For years, Google has never disclosed the specifics of its data center.
