Note that the final output is also key-value pairs and not a list, but aggregated one. Contrary to edge solutions, a data centre or a cloud-based system is designed to store, process and analyse massive volumes of data for deeper insights using powerful data analytics engines and machine learning mechanisms which edge systems would never be able to support. Four Stages IoT Architecture The four-stage IoT architecture can be summarized as follows: Sensors and actuators Internet getaways and Data Acquisition Systems Edge IT Data center and cloud More complex patterns include processing of graphs or iterative message passing, counting unique (distinct) values, data organization (for further processing), cross-correlation, Relational patterns like selection, projection, intersection, union, difference, aggregation and joins can also be implemented in IoT Architecture terms. Out of the vast data received from publishers or ad networks (like Google), some clicks might be fraudulent or non-billable. We get the final output that we saw above, Rather than categorizing certain situations as disadvantages of IoT Architecture, we would instead prefer saying that IoT Architecture may not be the best solution in some scenarios. For example, (movie, ) where movie name is the key and the value can be a tuple containing the user name and their respective ratings. In view of this, one of the challenges of using IoT within healthcare monitoring is providing data security and privacy. As intermediaries between the connected things and the cloud and analytics, gateways and data acquisition systems provide the necessary connection point that ties the remaining layers together. In our houses, smart lights, smart cameras, and smartwatches are connected with the internet that helps us get real-time data that can be further used for in-depth analysis and decision making. Physical/device layer. One workable view frames IoT as the use of network-connected devices, embedded in the physical environment, to improve some existing process or to enable a new scenario not previously possible. This risk is addressed by the IoT Architecture programming model by working with hdfs and HBase that allows high security allowing only the approved user to operate on the stored data in the system.
