A data center or data centre is a facility used to house computer systems and associated components, such as telecommunications and storage systems.
Data centers are simply centralized locations where computing and networking equipment is concentrated for the purpose of collecting, storing, processing, distributing or allowing access to large amounts of data. They have existed in one form or another since the advent of computers.
In the days of the room-sized behemoths that were our early computers, a data center might have had one supercomputer. As equipment got smaller and cheaper, and data processing needs began to increase -- and they have increased exponentially -- we started networking multiple servers (the industrial counterparts to our home computers) together to increase processing power. We connect them to communication networks so that people can access them, or the information on them, remotely. Large numbers of these clustered servers and related equipment can be housed in a room, an entire building or groups of buildings. Today's data center is likely to have thousands of very powerful and very small servers running 24/7.
Munich, Bavaria’s capital, is home to centuries-old buildings and numerous museums. The city is known for its annual Oktoberfest celebration and its beer halls, including the famed Hofbräuhaus, founded in 1589. In the Altstadt (Old Town), central Marienplatz square contains landmarks such as Neo-Gothic Neues Rathaus (town hall), with a popular glockenspiel show that chimes and reenacts stories from the 16th century.
