So consider this: What would happen if one of these monster forces of nature were to hit a major cloud data center? Here’s an examination of the potential impact, but to see just how influential some of these clouds are, it’ll be assumed that the respective cloud providers have no protocol for a power outage (although this is not the case).
Worst Case Scenario
Where would the most damaging hit be? It’s debatable, but the most detrimental hit may be in Virginia. Amazon Web Services (AWS) has one of their major centers in Northern Virginia. Rackspace—probably its closest competitor—has two data centers in Virginia, as well. And Virginia isn’t a stranger to natural disasters. Between 1851 and 2009, 12 hurricanes hit the state of Virginia. Unfortunately, according to a 2010 article in Nature Geoscience, some projections (based on high-resolution dynamical models and on theory) show that the globally averaged intensity of tropical cyclones will shift toward storms that are stronger. Greenhouse warming would cause this shift, and the storm intensity is projected to increase 2-11% by 2100. While there are studies that project a decrease in the globally averaged frequency of tropical cyclones, there are also projections that there will be increases in the frequency of the strongest cyclones. Hypothetically, if an incredibly strong storm pummeled through the centers located in Virginia, the Internet could suffer greatly. When only considering Amazon’s cloud (including all of its data centers), an incredible amount of information would be affected. In a study involving millions of people, ⅓ of those surveyed reported visiting a website every day that used Amazon’s infrastructure. In 2011, Amazon’s S3 cloud stored 762 billion objects. It’s possible that Amazon’s cloud alone holds an entire 1% of the Internet.Breakdown of the Loss
Hundreds of companies use the Virginia AWS center, but here’s a look at some major websites that are at least partially supported by Amazon Web Services (according to The New York Times) and what it would mean if they went down:- Pinterest -- As the 3rd most popular social network site, Pinterest’s absence would have a massive effect. According to AppData, Pinterest currently has 3.5 million daily active users.
- Netflix caters to countless customers—in the last three months of 2011 alone, more than 20 million subscribers from all over the world viewed movies and TV shows using this service, according to Boston.com.
- Reddit experiences thousands of viewers each day and even reached 100,000 unique visitors at one time in January 2012, according to Mashable. Operating with more than 100,000 subreddits as of December 2011, it’s clear a lot of information would miss out on being shared if the site were to be unavailable.
- Instagram has more than 30 million registered users uploading about 5 million photos every day, according to their press center. You better believe many would notice if their go-to photo service was no longer available.
