Microsoft’s Project Natick brings data centers underwater
Jordan Novet January 31, 2016 9:11 PM

Microsoft today unveiled Project Natick, a fascinating research initiative that could bring cloud computing infrastructure closer to big cities near large bodies of water — by putting data centers underwater

Microsoft isn‘t running any web services, like Office 365, through the data center infrastructure inside of these capsules. But Microsoft did build one (named the Leona Philpot, after the Halo character) and set it 30 feet underwater off of the California coast for four months in 2015. The capsules could have their computing hardware replaced every five years, but eventually they could well be kept underwater, without people onsite, for 20 years or more. And they could be powered by renewable energy, too. 

"Project Natick reflects Microsoft‘s ongoing quest for cloud datacenter solutions that offer rapid provisioning, lower costs, high responsiveness, and are more environmentally sustainable,‖ Microsoft explained on the website for the project. 

It‘s an unusual and forward-looking way for a company at Microsoft‘s scale — or any scale, really — to operate its core data center infrastructure. It‘s reminiscent of the Google barge that some people suspected had been intended to house data center hardware. (Other reports suggested it could be used for retail purposes.) But that project has been forgotten. Major web companies like Google and Facebook are now focusing on using aircraft to deliver the Internet to people, which has taken up some of the spotlight on research into new or better ways to deliver services. But the servers, storage, and networking equipment have got to live somewhere.

One might think putting data centers in the ocean might have environmental repercussions. But Microsoft is indicating that nothing untoward happened in the initial experiment. 

"During our deployment of the Leona Philpot vessel, sea life in the local vicinity quickly adapted to the presence of the vessel,‖ Microsoft said on the Project Natick website. 

Now Microsoft is looking to advance the research by building larger capsules. People working on the project have begun devising one three times as large as the first, according to John Markoff of the New York Times.

History and Debate of Internet Censorship

Censorship refers to any action taken by a society to control access to ideas and information. Throughout history, many different types of societies, including democracies, have used censorship in various ways. The issue is increasingly important due to the rapid development of new communication technology. As innovators continue to create new ways for people to share information, many people are now arguing over the issue of censorship. 

Pros and Cons of the Internet Censorship Debate

For the proponents of censorship, restricting the access of information is something that can provide benefits to society. By censoring pornography on the internet, children are less likely to encounter it. By censoring certain types of images and videos, society can prevent offensive or vulgar material from offending those that it targets. For example, some would argue that society should censor material that is insulting to a particular religion in order to maintain societal harmony. In this way, censorship is viewed as a way to protect society as a whole or certain segments of society from material that is seen as offensive or damaging. 

Some argue that censorship is necessary to preserve national security. Without using any kind of censorship, they argue that it is impossible to maintain the secrecy of information necessary for protecting the nation. For this purpose, censorship protects a state's military or security secrets from its enemies who can use that information against the state. 

Those who are against censorship argue that the practice limits the freedoms of speech, the press and expression and that these limitations are ultimately a detriment to society. By preventing free access to information, it is argued that society is fostering ignorance in its citizens. Through this ignorance, citizens are more easily controlled by special interest groups, and groups that are able to take power are able to use censorship to maintain themselves. Additionally, they argue that censorship limits a society's ability to advance in its understanding of the world. 

Another main issue for those who are against censorship is a history of censorship abuse. Those who argue against censorship can point to a number of examples of dictators who used censorship to create flattering yet untrue images of themselves for the purpose of maintaining control over a society. They argue that people should control the government instead of the government controlling its people.
