Welcome to the Zettabyte Era

ZBWelcome to the Zettabyte Era

In the last few years, a company that you might not think of when it comes to data centers and big data has made some dramatic changes in their strategy and offering: Cisco Systems. The company that for years has been the first name in networking has made some big bets and taken some risky initiatives to go from “the network is the platform” to the #2 blade server vendor, tied with IBM behind HP. This gives them a huge presence in the data center in terms of both network as well as computing.

This gives Cisco a unique perspective on where the industry is going, and where the market is poised to go, even in the next few years — especially in the use of Internet traffic.

Here are some key predictions from Cisco’s Visual Networking Index and an infographic that captures this picture of the future. Can you guess what is the #1 driver of Internet Protocol use? Next year it’s expected to surpass 50% of consumer Internet traffic. Read below:


By 2015:

  • Global Internet Protocol traffic: 1 zettabyte, which is equal to a sextillion bytes, or a trillion gigabytes.
  • Growth of global Internet traffic: 4X or 32% annual growth, and reaching 966 exabytes per year.
  • Number of network-connected devices: +15 billion, twice the world’s population.


  • Increase of Internet traffic between 2014 and 2015: 200 exabytes, greater than the total amount of Internet Protocol traffic generated globally in 2010.

Drivers of global IP traffic growth:

  1. An increasing number of devices: Proliferation of tablets, mobile phones, connected appliances and other smart machines drives demand for connectivity.
  2. More Internet users: By 2015, there will be nearly 3 billion Internet users, more than 40% of the world’s projected population.
  3. Faster broadband speed: Average fixed broadband speed expected to increase 4X, from 7 megabits per second in 2010 to 28 Mbps in 2015.
  4. More video: By 2015, 1 million video minutes –the equivalent of 674 days –will traverse the Internet every second.

Total Global IP Traffic in “Bytes”:

  • Global IP traffic:
    • 2010: 20.2 exabytes per month
    • 2015: 80.5 exabytes per month
  • Average global IP traffic in 2015: 245 terabytes per second, equivalent to 200 million people streaming an HD movie (1.2 Mbps) simultaneously every day.

Regional Trends:

  • By 2015, the Asia Pacific region will generate the most IP traffic — 24.1 exabytes per month — surpassing last year’s leader, North America (22.3 exabytes per month), for the top spot.
  • The fastest-growing IP-traffic regions for the forecast period (2010 – 2015) are the Middle East and Africa (which had a 52% compound annual growth rate, for an 8X growth), surpassing last year’s leader Latin America (48% CAGR, 7X  growth).

#1 Growth Driver: Consumer Video

  • Global online video community will increase by approximately 500 million users by 2015, up from more than 1 billion Internet video users in 2010.

Global Device Growth:

  • In 2010, PCs generated 97% of consumer Internet traffic. This will fall to 87% by 2015, demonstrating the impact that devices like tablets, smartphones and connected TVs are having on how consumers access and use the Internet.
  • Web-enabled TVs access to the Internet continues to grow and by 2015, 10% of global consumer Internet traffic and 18% of Internet video traffic will be consumed via TVs.

3DTV and HD (Advanced Video)

  • Global advanced video traffic, including three-dimensional (3-D) and high-definition TV (HDTV), is projected to increase 14X between 2010 and 2015.

Mobile Broadband:

  • Global mobile Internet data traffic will increase 26X from 2010 to 2015, to 6.3 exabytes per month (or 75 exabytes annually).

Global File Sharing:

  • Global peer-to-peer traffic will account for 16% of global consumer Internet traffic, by 2015, down from 40% in 2010.

Global Business IP Traffic:

  • Business IP video conferencing: 6x growth by 2015, growing more than 2X as fast as overall business IP traffic, at a CAGR of 41% from 2010 to 2015.

Cloud, How Big Is It?

Cloud QuestionCLOUD, HOW BIG IS IT?

The Cloud, it’s Huge! But what does that mean? Let’s start with numbers we are familiar with, then see how it grows to numbers we have a harder time getting our head around:

  • Starting with a binary digit, or “bit”
  • 8 bits makes a “byte” or a character on a page
  • Then about a thousand of those, or a “kilobyte”. Two kilobytes is about a page of information
  • Then add 3 zeros to the end of that, or a “megabyte.” Two or three megabytes is about the size of a digital song
  • Adding another 3 zeros to the end of that and you have a “gigabyte.” Computer laptop memory (RAM) and iPod capacities are usually measured in Gigs
  • 3 more zeros on the end of that and you have a “terabyte.” Computer hard drives (disks) are measured in TBs
  • Another 3 more zeros and you have a “petabyte.” The capacity of large data storage arrays are measured in PBs.
  • When you add 3 more zeros or orders of magnitude (powers of ten) you have an “exabyte”. One of those represents the amount of mobile data traffic used in the US last year, according to an analyst
  • Another 3 zeros gets us to the “zettabyte” scale, a number not yet in common parlance, but that represents about the entire global digital data used back in 2009
  • 35 of those “zettabytes” is the forecast for digital data use by 2020, just 9 years from now
  • About a third of that will be in the Cloud.

A “yottabyte”? No relation to the Jedi Master.

State of the Internet: Email


It is regularly being said that “Email is dead.”

And while it’s true that Millennials often remain within the walled garden of Facebook or their mobile devices, email was the way most Boomers came to know messaging on the Internet.

I say:

“Email is dead, is dead.”

Long live email. Here’s a picture of what it looked like last year… along with statistics on websites, users, browsers, and social media: (click on image for a larger view)

Big numbers: US information consumption

I was impressed by some recent reports from the University of California at San Diego, and the research company IDC.

The first story reports that:

from all non-work sources in 2008, including TV, radio, movies, the Net, cell phones, video games and reading material…

US consumption totaled 3.6 zettabytes and 10,845 trillion words, corresponding to 100,500 words and 34 gigabytes for an average person on an average day. A zettabyte is 10 to the 21st power bytes, a million million gigabytes.

Now, that’s a lot of data!

The second story is interestingly connected. IDC reports that there are currently about 450 million mobile devices connected to the Internet. The total number of devices connected is about 1.6 billion. So, over a quarter of the devices connected to the Internet are mobile: mobile phones, smartphones, and other wireless devices!

And while the total number of Internet-connected devices is expected to grow to over 2.7 billion in the next three years, the number of such mobile connected devices is expected to more than double in that time.

Obama Inauguration: Info Extravaganza


This was not your grandfather’s Inauguration.

Grandpa might have listened over the radio, your parents viewed it on television, but this generation viewed/participated in it through so many different media.

In my article on the History of Inauguration Day, I said that:

…the event will be covered simultaneously by networks, live Internet streaming video, as well as coverage via Twitter, Facebook, YouTube, MySpace, blogs, and Hulu… It will not be just the number of people who are physically present at the Inauguration, many times the 30K at Lincoln’s swearing in. Consider the amount of information that will be generated, distributed, replicated, commented upon, redistributed, and repurposed — much of it in real-time for those “virtually” attending. From high-resolution video to low-bandwidth text messages, from long webcasts to short SMS messages, the cables and airwaves will be lit up. As the first “wired” — or is it wireless — President Barack Obama gives his inauguration speech, American’s heads will be in the Internet cloud.

Personally, I was watching it on TV, while on my iPhone tracking Twitter and Ustream.tv. Let’s look at some of the statistics of the online information available.

On Inauguration Day, by early afternoon:


  • Claimed it served almost 19 million live video streams, almost four times the feeds of Election Day
  • Obama’s Facebook Fan Page has more than 4 million fans and in excess of 500,000 wall posts
  • CNN had served 13.9 million live video streams globally since 6am
  • CNN had broken its all time total daily streaming record (from Election Day) of 5.3 million live streams.


  • Had a partnership with CNN, as well as a number of “applications” enabling participation with the event. They claimed:
  • 600,000 status updates posted through the CNN.com Live Facebook feed
  • Averaged 4,000 status updates per minute during the broadcast
  • 8,500 status updates were posted during the first minute of Obama’s speech
  • “Millions” of people logged into Facebook during the broadcast



  • Had a variety of feeds, available in different formats


  • Did a PhotoSynth of the Inauguration inviting anyone to send in their photos which would be stiched into a virtual 3D representation of the The Moment. Scores of people sent in multi-megabyte files.

How did you participate in the Inauguration?
