Study Notes
Overview of IoT Architecture and Hardware Virtualization
- IoT applications are being used to create smart cities.
- The physical layer of IoT Architecture refers to the actual devices that make up the IoT system.
- The physical layer includes sensors, actuators, gateways, and other types of hardware.
- Communication protocols and standards, such as Bluetooth, Wi-Fi, Zigbee, and LoRaWAN, are used to transmit data between devices.
- The connectivity layer manages the communication between devices in the system and includes network protocols, gateways, and routers.
- The platform layer processes and analyzes the data collected by the physical layer and includes cloud platforms, databases, and analytics tools.
- The application layer allows users to interact with the IoT system and make decisions based on the data.
- Microcontrollers are essential components of IoT devices, responsible for processing and controlling data.
- Power management is critical for IoT devices, and techniques such as sleep modes, duty cycling, and energy harvesting can be used to reduce power consumption.
- Cloud platforms provide storage, processing, and analysis of data from IoT systems and include Amazon Web Services, Microsoft Azure, and Google Cloud Platform.
- Hardware virtualization is the creation of a virtual machine over existing operating systems and hardware.
- Virtualization refers to partitioning the resources of a physical system into multiple virtual resources and is a key enabling technology of cloud computing.
