The Insane Growth of the Mobile Cloud: Big Data

Zetta Yourself In, Because We're Going to Talk About A Yotta Storage

Big Data used to be confined to a few big problems being worked on by small numbers of people-meteorology, epidemiology, nuclear bomb simulations, other scientific applications.

Now a combination of ubiquitous sensors, continuous surveillance, and proliferating smart devices has brought Big Data into the realm of innumerable small problems being requested by very large numbers of people.

Never mind the 600 millions of MicroSkype users and Facebook friends; think of 4 billion handhelds all streaming Sponge Bob or the latest Xollywood flicks.

I just posted my observations on a very small aspect Big Data growth-the scene in the Philippine. Now I'd like to address the global scope of Big Data.

A Boatload, in Layman's Terms
On this topic, I recently heard of Gartner figures that estimate the world will need 1.2 zettabytes of remote storage by the year 2020.

That's 1.2 trillion gigabytes, or 1.2 billion terabytes. At current prices of about 8 cents a gigabyte that's about $100 billion USD in storage, plus the costs to buy, house, and cool the processing power needed to support it.

(Given the continuous drop in storage prices, that number could be half this amount by next week and only 10% of it by 2020.)

Imagine slightly more than half the people of the world having a handheld device. Imagine, then, 4 billion devices, and imagine each user wanting 100 gigabytes of storage. Imagine 400 billion gigabytes.

That 400 billion gigabytes is equal to 400 exabytes. Heck, we're already one-third of the way to the 1.2-zettabyte level!

So a zettabyte is a big number, but maybe not that big a number.

A report from IDC in 2008 estimated a "digital universe" in the hundreds of exabytes at that time already-including all those BlueRay DVDs sitting around, as well as data that is transmitted but not necessarily re-stored (think of a YouTube video viewed by 1 million people who don't download it).

The IDC report also estimated that enterprise IT created only 5% of this digital footprint. Clearly, as I wrote in the lede of my other article, "the mobile web is on the verge of accelerating worldwide computing and bandwidth requirements to a degree unimaginable just a few years ago."

And I think Cloud Computing is the only way to tame this enormous data monster. Can we realistically expect to plan and deploy-and keep up-without Cloud's elasticity, fluidity, and metered delivery model?

What Shall We Name This Baby?
In any case, it may well be that we run out of names for these large-scale numbers in the lifetimes of some people alive today (if not the lifetimes of most of my readers). The current system ends at the yottabyte, just one magnitude higher than the vaunted zettabyte.

It's already very difficult for the slow ones amongst us (such as me) to keep these terms straight. So I think that soon enough we'll start expressing these massive amounts of information in either exponential or binary terms.

Instead of saying exabyte and zettabyte, maybe we'll say 18byte (as in 10 to the 18th power) and 21byte, or 60byte (as in 2 to the 60th power) and 70byte.

Does anyone have a better, more poetic idea than this? I hope so.

IoT & Smart Cities Stories
The deluge of IoT sensor data collected from connected devices and the powerful AI required to make that data actionable are giving rise to a hybrid ecosystem in which cloud, on-prem and edge processes become interweaved. Attendees will learn how emerging composable infrastructure solutions deliver the adaptive architecture needed to manage this new data reality. Machine learning algorithms can better anticipate data storms and automate resources to support surges, including fully scalable GPU-c...
Machine learning has taken residence at our cities' cores and now we can finally have "smart cities." Cities are a collection of buildings made to provide the structure and safety necessary for people to function, create and survive. Buildings are a pool of ever-changing performance data from large automated systems such as heating and cooling to the people that live and work within them. Through machine learning, buildings can optimize performance, reduce costs, and improve occupant comfort by ...
The explosion of new web/cloud/IoT-based applications and the data they generate are transforming our world right before our eyes. In this rush to adopt these new technologies, organizations are often ignoring fundamental questions concerning who owns the data and failing to ask for permission to conduct invasive surveillance of their customers. Organizations that are not transparent about how their systems gather data telemetry without offering shared data ownership risk product rejection, regu...

Poor data quality and analytics drive down business value. In fact, Gartner estimated that the average financial impact of poor data quality on organizations is $9.7 million per year. But bad data is much more than a cost center. By eroding trust in information, analytics and the business decisions based on these, it is a serious impediment to digital transformation.

Predicting the future has never been more challenging - not because of the lack of data but because of the flood of ungoverned and risk laden information. Microsoft states that 2.5 exabytes of data are created every day. Expectations and reliance on data are being pushed to the limits, as demands around hybrid options continue to grow.

Enterprises have taken advantage of IoT to achieve important revenue and cost advantages. What is less apparent is how incumbent enterprises operating at scale have, following success with IoT, built analytic, operations management and software development capabilities - ranging from autonomous vehicles to manageable robotics installations. They have embraced these capabilities as if they were Silicon Valley startups.
As IoT continues to increase momentum, so does the associated risk. Secure Device Lifecycle Management (DLM) is ranked as one of the most important technology areas of IoT. Driving this trend is the realization that secure support for IoT devices provides companies the ability to deliver high-quality, reliable, secure offerings faster, create new revenue streams, and reduce support costs, all while building a competitive advantage in their markets. In this session, we will use customer use cases...
