The term smart city includes the usage of information and communication technologies (ICT) for developing and improving the quality of urban services such as transportation, electricity usage, water usage, industrialization. The overall aim of a smart city is to reduce the greenhouse gases emitted from the usage of vehicles, machinery, industries, and transport systems to enhance the quality of people living in a smart city.
The measure of environmental parameters contributes hazards in the smart city have gained more importance since it affects the people living in the urban area directly and indirectly. The challenge in this scenario is how to store and process the tremendous amount of data created in real-time and offline by the Sensor devices placed all around the smart city. The solution can be obtained for this scenario by using Alibaba Cloud product, PolarDB.
PolarDB is a Cloud-native database developed by Alibaba Cloud, it provides high-performance, massive storage, secure and reliable database storage services which can be used to store a large amount of real-time data. Various features of PolarDB include:
The environment parameters are the water and air pollutant which pave the way for the greenhouse effect. The various environment pollutants include Carbon Dioxide, Carbon Monoxide, Nitrous Oxide, Methane, Ozone, sulphur-dioxide, Chlorofluorocarbons, Hydro-fluorocarbons, Sulphur hexafluoride, Nitrogen trifluoride. One of the challenges of capturing those pollutants information is the huge amount of data generated every day. In this scenario, we can use Alibaba Cloud's database PolarDB to store all those real-time data from various sources. Figure 1 explains the detailed architecture to use PolarDB to store the environmental parameters of the Smart City system.

The architecture consists of the following modules
This is the source of the environmental data, such as a vehicle, household items, plants. For example:
Internet of Things (IoT) refers to the network of connected objects that can collect and exchange data using embedded sensors. It is nowadays finding profound use in each sector and plays a key role in the proposed environmental monitoring system too.
Sample sensors used in the environmental data collection are:
Since the amount of real-time data generated from the IoT device module are huge, for better data storage and management, Alibaba Cloud PolarDB is introduced. PolarDB uses an architecture with computing-storage separation., where the compute nodes and storage nodes are interconnected through a 25 Gbit/s high-speed remote direct memory access (RDMA) network and communicate with each other through the user-state network protocol layer of the Bypass kernel. This ensures the low latency of transactions and query statements and reduces the latency of state synchronization between compute nodes.
The environment pollutant and greenhouse gases are the major cause of serious health issues for the people in a smart city. The data generated in this use case is tremendous which cannot be handled by the ordinary traditional database. This article explains how to store the real-time and offline data generated by the IoT device in the Cloud by using Alibaba Cloud PolarDB product.
