INTRODUCTION
Azure IoT Hub or the Azure Internet of Things provides us with a cloud-hosted back-end to virtually connect to any possible device. It is a coagulated form of cloud services that are further managed by Microsoft for monitoring, pertaining and regulating the assets of the Internet of Things.
In other words, the Azure Internet of Things is a one-stop solution that works and operates in the cloud.
The Azure cloud platform comprises more than 200 products as well as cloud services that are designed to help consumers with better solutions. It is benefited by continuous innovations and promotes development for today as well as for the future that lies ahead.
Azure IoT Hub is made up of one or more devices and many back-end services that disseminate with each other.
IoT Hub supports and fastens multiple messaging patterns such as the file uploading from devices to control the devices from the cloud.
It is a service that is organized and hosted in the cloud and it acts as a central messaging hub for communication between an IoT application and the device it manages and is in charge of it.
Azure IoT Hub
Internet of Things (IoT) puts forward businesses immediate as well as real-world opportunities to lower and reduce the costs, escalate revenue, and also transform their businesses.
Azure IoT Hub is a managed IoT solution that is collocated in the cloud.
This cloud-to-cloud device connectivity intends that one can receive data from their devices, but can also send commands back to the devices. Azure IoT differs from the existing solutions as it also provides the infrastructure to authenticate, connect and manage the devices connected to it.
Azure IoT Hub provides,
Device libraries for the most commonly, habitually as well as frequently used platforms and languages for convenient and easy device connectivity.
Safe and secure communications with multiple options for device-to-cloud and cloud-to-device hyper-scale communication.
Advantages offered by Azure IoT Hub
Azure IoT Hub allows safe and secure communications. It also gives the access to control the use of per-device security keys. It gives us heavy monitoring for connectivity of devices and device identity management as well. It is inclusive of device libraries. This is for popular platforms as well as languages.
SERVICES OFFERED BY Azure IoT Hub
Microsoft is offering eight different IoT services in Azure. One must figure out sincerely, which one of these options or services would fit their needs well. Some of these services are –
IoT Central: It makes the platform of IoT solutions way simpler and assists to reduce the heavy load and expense of IoT management operations as well as development. The basic intention of this particular service is a straightforward, clear-cut solution that doesn’t need any service customisation.
IoT Solution accelerators: It is a group of PaaS solutions that can be used to escalate the development of an IoT solution.
IoT Hub: This particular service allows you to control a considerable number of IoT devices, which can even go up to a billion, by logging into an IoT hub from your device. The utmost need for this would arise when you want communication that goes both ways between your devices and back-end. It is the primary and fundamental service for IoT solution accelerators and IoT Central.
IoT Hub Device Provisioning Service: It assists IoT Hub in a way that you can use to safely and securely provision devices on your IoT hub. Rather than provisioning a lot of devices one at each time, this service offers you the prerogative to quickly and easily provision millions of devices all at the same time.
IoT Edge: This service can be used to analyse data on IoT devices instead of in the cloud. It builds on the very top of the IoT Hub.
MQTT
MQTT (Message Queuing Telemetry Transport) is nothing but a lightweight messaging protocol that was developed by IBM and was first released in 1999.
MQTT can also be defined as a publish-subscribe network protocol that transports messages between devices. It translates messages between devices, servers and applications.
Initially, the MQTT protocol was created to link sensors on oil pipelines with communication satellites, with prominence on minimal battery loss and bandwidth consumption.
A few out of the several benefits offered by MQTT are minimized data packets, energy efficiency, real-time operation with little to no delay, and retained messages that clients automatically receive after subscribing.
Conclusion
Azure IoT hub is and always has been a one-stop solution and destination when it comes to virtual connections. In the contemporary world of IoT, the Azure IoT hub is something that everyone will blindly go for. Its obsession and truthfulness with safety and security catch the eye of people at the helm of working.
It provides the access to control the use of per-device security keys. It also assists us with heavy monitoring for connectivity of devices and device identity management.
