AWS IoT Core

What is AWS IoT?

Without infrastructure management, AWS IoT Core connects and secures billions of IoT devices and routes trillions of IoT communications to AWS services and other devices. The user just pays for the elements they utilize. There are no minimal (or) obligatory service fees. Connectivity, messaging, device shadow usage, registry usage, and rules engine consumption are all taxed individually. Regardless of the nature of your task, this technique gives you transparency and a reasonable price.

AWS IoT enables you to choose your solution's most relevant and current technology. AWS IoT Core supports the following protocols to assist you in managing and supporting your IoT devices in the field:

• MQTT (Message Queuing and Telemetry Transport)
• MQTT over WSS (Websockets Secure)
• HTTPS (Hypertext Transfer Protocol - Secure)
• LoRaWAN (Long Range Wide Area Network)

To publish and subscribe to messages, the AWS IoT Core message broker supports devices and clients that use the MQTT and MQTT over WSS protocols. It also supports devices and clients that use the HTTPS protocol to publish messages.

AWS IoT Core for LoRaWAN connects and manages wireless LoRaWAN (low-power long-distance Wide Area Network) devices. AWS IoT Core for LoRaWAN eliminates the requirement for you to build and maintain a LoRaWAN Network Server (LNS).

How Your Devices and Apps Access AWS IoT

For AWS IoT tutorials, AWS IoT provides the following interfaces:

• SDKs for AWS IoT Devices Create apps on your devices to send and receive messages through AWS IoT.
• LoRaWAN AWS IoT Core Using AWS IoT Core for LoRaWAN, you can connect and manage your long-range WAN (LoRaWAN) devices and gateways.
• Amazon Web Services Command Line Interface (AWS CLI) Run AWS IoT commands on Windows, macOS, and Linux. You may use these commands to create and manage item objects, certificates, rules, jobs, and policies.
• AWS IoT API—Create IoT apps that use HTTP (or) HTTPS queries These API operations let you programmatically create and maintain item objects, certificates, rules, and policies.
• SDKs for AWS Create IoT apps with language-specific APIs. These SDKs cover the HTTP/HTTPS API and allow you to program in any of the supported languages.

You can also access AWS IoT through the AWS IoT console, which provides a graphical user interface (GUI) for configuring and managing your IoT solution's objects, certificates, rules, tasks, policies, and other components.

How it Works?

AWS IoT Core provides services to assist Internet of Things applications. So let us begin by reviewing the essential components of the AWS IoT Core Universe:

• Actuators  Devices that allow the gadget to control things in the external environment. Stepper motors and relays are two examples.

AWS IoT Services

AWS Internet of Things provides solutions that enable gadgets to engage with the outside environment as well as the information that flows across them and Amazon IoT in an Internet of Things context. To support your IoT ecosystem, AWS IoT includes the capabilities represented inside this figure.

AWS IoT Data Services Using the AWS IoT services listed below, you may analyze data from your IoT solution's devices and take relevant action.

• Kinesis Video Streams It is simple to safely transmit video from connected components to Amazon Web Services for analytics, machine learning (ML), playback, and other processing thanks to Amazon Kinesis Video Streams. To automatically provide and elastically grow the infrastructure required to ingest streaming video data from millions of devices, use Kinesis Video Streams.
• WebRTC Video Streams WebRTC is an open-source project that provides real-time media streaming and communication between web browsers, mobile apps, and connected devices via basic APIs, and it is also supported by Kinesis Video Streams. Peer-to-peer media streaming and video chat are examples of typical usage.
• IoT Analytics AWS IoT Analyses is a fully-managed service that makes it simple to operate sophisticated analytics on enormous amounts of IoT data without having to worry about the expense and complexity involved in developing an IoT analytics platform.
• IoT Events It is simple to recognize and respond to events from IoT sensors and apps with the help of AWS IoT Events, a fully managed service. Events are patterns in data that reveal conditions that are more complex than anticipated, such as equipment adjustments when a belt becomes stopped or motion sensors using motion signals to turn on lights and security cameras.
• FleetWise IoT AWS In order to create apps with analytics and machine learning that enhance vehicle quality, safety, and autonomy, manufacturers may utilize FleetWise to gather, convert, and send vehicle data to the cloud in near-real time.
• SiteWise A managed service called SiteWise makes it easier to gather, arrange, and analyze data on industrial equipment.
