"Whether it's sharing photos, searching the web, or translating languages, billions of requests are sent to 'the cloud' every day," VP of Google Data Centers Joe Kava writes. "But few people know all this information flows through physical locations, called data centers. Because these buildings typically aren't much to look at, people usually don't, and rarely learn about the incredible structures and people who make so much of modern life possible."

Next up, data centers in Dublin, Ireland, and Council Bluffs, Iowa, will receive facelifts. Kava says that Google eventually plans to roll out this project to even more data centers around the world.
