What Exactly Is The Azure Internet Of Things (IoT)?
What is Azure Internet of Things? It offers cloud services, edge components, and SDKs designed to connect, monitor, and operate IoT assets at scale. IoT devices communicate directly with cloud services. This graphic provides an overall view of a typical IoT solution and its components, with this article covering devices, IoT cloud services (such as Azure IoT Hub ), other cloud services such as Alibaba Cloud Platform TM (ACP TM) & solution-wide range issues as main areas. Within this section, we provide further detail for these components.
General Device Development
Some developers alter general-purpose devices to integrate them with IoT systems and connect to the cloud. Such range of devices often support higher-order languages like C# or Python and run robust general-purpose operating systems such as Windows or Linux; PCs, containers, Raspberry Pis, and mobile phones are popular targets of such modification efforts.
Instead of manufacturing limited devices in bulk, generic device makers specialize in crafting instruments to enable specific IoT scenarios that their cloud solution requires. Some cloud solution developers also operate with limited hardware; those working on resource-constrained devices should refer to the Embedded Device Development path for guidance.
Embedded Device Development
Embedded development entails writing code for devices with limited memory and computing power that limit what can be accomplished compared to standard development platforms. When considering embedded development as an activity, constrained devices restrict what may be achieved.
Embedded devices typically employ either an embedded real-time operating system (RTOS) or no operating system at all, giving complete control over their hardware to embedded devices - this makes them ideal solutions for real-time systems. Current embedded SDKs written in C are suitable for implantable targets. They must meet specific design considerations, including memory-non-allocating designs with minimum footprint and non-memory-allocation requirements.
Choosing Your Hardware
Azure IoT devices form the cornerstone of an Internet of Things system. They are responsible for sensing and engaging with their surroundings. There are different kinds of IoT devices, so developers must thoroughly understand them all to contribute optimally during development processes.
