IoT and Big Data are two sides of a coin. IoT systems will be streaming lots of data in heterogeneous forms which will have to be managed by the organisation. It is the biggest challenge which the organization will face. Thus, it is quite clear that both IoT and Big Data technologies will have to be used together to realize its full potential.
IoT will provide the important and interesting data, for e.g. data from sensors and actuators, but just the data collection is not enough. For better outputs, these data has to be studied, interpreted, analysed and insights has to be derived for better functioning of the IoT devices as well as business functions.
With IoT, one of the foremost things to be concerned of is huge, continuous stream of data coming into organization’s data storage. Hence the data centres must be prepared to handle this supplementary load of heterogeneous data and the companies will have to adapt technologies which can be mapped with IoT data.
After upgrading the data centres to match with IoT systems, proper analytics platform should be put in place. The actions to be taken on IoT data are different than any other data streaming. These actions are correlated to events and based on metric calculations. Hence analytics solutions for managing the IoT data will be done keeping in mind these actions.
The various examples of IoT and Big Data –
- Transportation industry – It places sensors in their vehicle to track them and a closer eye on them but more importantly, it provides data like on – fuel efficiency, delivery routes and time given by drivers. This information is useful in making the transportation more efficient and productive by optimization.
- Manufacturing – They place IoT sensors to machines and collect important data about the equipment which gives them clear idea about the performance, whether maintenance is required and if yes then when by which machine breakdown or the accidents can be avoided. Even by timely repairs based on the feedback data given by sensors, business end up saving money from accidental bigger expense.
- The most common example is wearable. For an e.g. fitness band gives us lot of data of current fitness routine and how our body is responding to it, accordingly we can change our fitness routine.
Thus internet of things and big data go hand in hand. Tremendous growth is going parallel in both the fields and both rely on success of each other. As more and more IoT systems are put in place and more and more data is generated and hence IoT and big data will be more and more entwined.
