data center
¿Qué es un data center?
La traducción del término Data Centers sería Centros de Datos, refiriéndonos a los data centers de Google son los centros donde se procesan las páginas indexadas por el buscador, se procesa el algoritmo del PageRank y todos los aspectos que determinan los resultados de las búsquedas efectuadas en Google.
Como cada vez somos más millones de usuarios realizando búsquedas en Google cada minuto, la infraestructura del buscador sigue creciendo para atender las demandas de tantos usuarios, ampliándose progresivamente el número de centros de datos utilizados, pueden ser unos 20 en la actualidad y cada uno puede ofrecer diferentes resultados, aunque la realidad es que son muy similares en todos.
No se sorprenda si hablando con alguien por telefóno comprueba que el no ve los mismos resultados en Google con las mismas búsquedas que usted, lo más probable es que consulten data centers de google diferentes, este detalle no está visible en la dirección URL que usted visita del buscador. Ejemplo www.google.es usted no tiene porque distinguir si está en alguo de estos data center de Google, por poner algunos ejemplos:

CIO - In June, Iceland-based CCP Games brought the hammer down on a group of resource hogs that were clogging its data center.
In an operation dubbed internally "Unholy Rage," the company cut off 2 percent of its subscribers--real customers who had paid to play CCP's massively multiplayer online role-playing game (MMORPG), known as EVE Online. The small group of players was using software to essentially cheat at the game, automating the collection of resources and the completion of quests to generate gold. These so-called real-money traders would then sell the gold for real-world cash.
Such schemes not only wreak havoc on the virtual world's economy (CCP Games has its own on-staff economist), but the traders also have a significant impact on the company's real-world data center. Case and point: When the company cut off the devious 2 percent of its users, it gained back 30 percent of its computing resources.
"With the reduced load, we have directly impacted our ability to scale our infrastructure to higher user counts," says James Wyld, virtual world administrator for EVE Online, "so I would say we have saved on the next cycle of infrastructure costs."

Most enterprises may not think that their operating environment is similar to the virtual fantasy world of World of Warcraft or the digital universe of EVE Online. Yet their data exists in a virtual space all its own, whether that's a world of financial transactions, health data or sales information.
So for companies that want to shore up their virtual environments, here are some tips from the pros.
Know Your Infrastructure Costs
While EVE Online's virtual world encompasses nearly 5,000 star systems, Blizzard Entertainment's immensely popular fantasy MMORPG, World of Warcraft, has the most expansive
infrastructure. Where CCP Games has a single data center in the United Kingdom, Blizzard has four data centers in the United States, seven data centers in the European Union and more in Asia Pacific.
"Blizzard is one of the top-10 architectures," says Anthony Greenberg, founder and principal at RampRate, which advises companies on reducing their infrastructure costs. "They are massive."
Both companies have similar data-center considerations, however: An expanding subscriber base led them to rapidly build more infrastructure, although not necessarily in the most cost-effective way, says Greenberg.
"Most data centers have an explosively growing relationship with data, but most of them have 20- to 30-percent fluff," Greenberg says. "You need to know your costs as they compare to the market."
