How JSON and Big Data Will Shape the Internet of Things

RESTful APIs a key component in data interactions

The catchphrase "Internet of Things" may seem like a relatively new term, but in reality has been around since the late ‘90s, when there was a desire to more efficiently track the flow of goods for supply chain purposes. The enabling technology was RFID which made it possible to report on stock levels and inventory in real-time.

These days, the term "Internet of Things" has a much broader meaning than just supply chain technology. In the many years that have passed, big data and mobile technology have grown by leaps and bounds. This means that it is possible to crunch large amounts of sensor data and deliver context-relevant information to users on their smartphones. As a consequence, just about any physical object out there can be measured as long as there are sensors that can transmit this information. This has huge implications for global economic growth, and could lead to a 2 percent to 5 percent gain in GDP in 2025, according to a report from the Progressive Policy Institute

For relevant sensor data to be delivered, every single "Thing" that is connected to the internet needs to have an API that allows access to key data elements. This data must also be readily streamed quickly into a Big Data cluster so that contextual information can be served up in a timely manner.

While the API is a key component of ensuring that data is accessed in a RESTful manner, the format of the payload is also equally as important. JSON is not as verbose as XML and consequently does not contain detailed processing instructions. Being a lightweight data interchange format, it is faster to use JSON to send bits of data from a sensor. The increasing popularity of REST over SOAP in newer APIs only foreshadows greater usage of JSON as the preferred data interchange format.

To answer the question of why JSON would be the most widely used format for the Internet of Things, one only need look at the rapid development of Raspberry Pi, which started a little over two-and-a-half years ago, and has gained massive traction worldwide. This credit-card sized microcomputer is extensible, and a recent project called RaZberry has turned it into a device capable of controlling your home automation through - you guessed it - a JSON interface. With future development of the Internet of Things, the proliferation of JSON as the preferred data delivery mechanism will only increase.

Even more interesting is how this data can be fed into a Big Data cluster to perform predictive modeling and analytics. Just over a year ago, Google BigQuery added support for JSON and explicitly mentions how sensor data and its attributes can be measured as a consequence. With time, it is only inevitable that developers in other Big Data ecosystems will use JSON when setting up their clusters to perform analytics from the various source data from the Internet of Things.

We have an exciting few years ahead of us in the technology industry and the Internet of Things will play a large part in it. With the enabling technology of JSON, and the growth of Big Data, we are sure to witness many new breathtaking innovations in this area.

The major cloud platforms defy a simple, side-by-side analysis. Each of the major IaaS public-cloud platforms offers their own unique strengths and functionality. Options for on-site private cloud are diverse as well, and must be designed and deployed while taking existing legacy architecture and infrastructure into account. Then the reality is that most enterprises are embarking on a hybrid cloud strategy and programs. In this Power Panel at 15th Cloud Expo (http://www.CloudComputingExpo.com), moderated by Ashar Baig, Research Director, Cloud, at Gigaom Research, Nate Gordon, Director of T...

Nigeria has the largest economy in Africa, at more than US$500 billion, and ranks 23rd in the world. A recent re-evaluation of Nigeria's true economic size doubled the previous estimate, and brought it well ahead of South Africa, which is a member (unlike Nigeria) of the G20 club for political as well as economic reasons. Nigeria's economy can be said to be quite diverse from one point of view, but heavily dependent on oil and gas at the same time. Oil and natural gas account for about 15% of Nigera's overall economy, but traditionally represent more than 90% of the country's exports and as...
The Internet of Things is a misnomer. That implies that everything is on the Internet, and that simply should not be - especially for things that are blurring the line between medical devices that stimulate like a pacemaker and quantified self-sensors like a pedometer or pulse tracker. The mesh of things that we manage must be segmented into zones of trust for sensing data, transmitting data, receiving command and control administrative changes, and peer-to-peer mesh messaging. In his session at @ThingsExpo, Ryan Bagnulo, Solution Architect / Software Engineer at SOA Software, focused on desi...

We certainly live in interesting technological times. And no more interesting than the current competing IoT standards for connectivity. Various standards bodies, approaches, and ecosystems are vying for mindshare and positioning for a competitive edge. It is clear that when the dust settles, we will have new protocols, evolved protocols, that will change the way we interact with devices and infrastructure. We will also have evolved web protocols, like HTTP/2, that will be changing the very core of our infrastructures. At the same time, we have old approaches made new again like micro-services...
