Google Spanner Largest Single Database on Earth. Google began in January 1996 as a research project by Larry Page and Sergey Brin when they were both PhD students at Stanford University in Stanford, California. While conventional search engines ranked results by counting how many times the search terms appeared on the page, the two theorized about a better system that analyzed the relationships between websites. They called this new technology PageRank; it determined a website’s relevance by the number of pages, and the importance of those pages, that linked back to the original site. The giants in internet searching- Google bags the number 4th spot in top 10 largest databases (That was a number of years ago though this data was compiled). Although the exact size of Google’s database is unknown, it’s said that Google accounts every single search that makes each day into its database which is around 91 million searches per day. Google stores every search and makes patterns from previous searches so that the user can be easily directed. Google also collects information of their users and stores them as entries in their database which is said to expand over 33 trillion entries. On top of that Google has simply expanded their database with Gmail and Google ads and with their acquisitions like YouTube.

Google’s Web Operation and Spanner

googles-web-operation-and-spannerGoogle’s web operation is significantly more complex than most, and it’s forced to build custom software that’s well beyond the scope of most online outfits. But as the web grows, its creations so often trickle down to the rest of the world. Spanner is the first worldwide database worthy of the name — a database designed to seamlessly operate across hundreds of data centers and millions of machines and trillions of rows of information. Spanner is a creation so large, some have trouble wrapping their heads around it. But the end result is easily explained: With Spanner, Google can offer a web service to a worldwide audience, but still ensure that something happening on the service in one part of the world doesn’t contradict what’s happening in another. Google’s new-age database is already part of the company’s online ad system — the system that makes its millions — and it could signal where the rest of the web is going.
