Serverless architecture

The serverless approach lowers the cost of MVP and prototyping and increases the flexibility of the entire IoT application development process. Developers can concentrate on core tasks without worrying about maintaining server stuff. 

Robust analytics

Amazon introduces a range of powerful analytics tools for analyzing data across the IoT ecosystem. They turn raw data into valuable material for calculations, use various analytics and visualization methods to extract information, and prepare them for machine learning.

High-security standards

IoT security matters, which is why Amazon carefully protects all devices, communications, and customer data. AWS implements a strong authorization, authentication, and encryption level to ensure communications security between the IoT platform and joined devices.

Extensive partner network

Amazon actively partners with numerous IoT software vendors and device manufacturers. This way, you can be sure that hardware compatibility will not severely constrain your IoT apps.

Integration with AWS products and services

The AWS IoT permits developers to connect IoT devices and leverage other Amazon web services. That is convenient because you don’t have to switch to another service to add an extra feature.

Flexible pricing

Amazon proposes a friendly pricing model – you pay for what you utilize. Amazon IoT core pricing is based on connection time, message count, registered devices, and more. There are no default service charges or upfront charges.

AWS IoT Benefits for Your Business

What are the AWS IoT services?

Amazon’s platform solves all the problems associated with IoT products and services. That allows enterprises to deliver commercial, industrial, and customer IoT solutions without disrupting infrastructure management. AWS IoT services fall into three categories: 

Device software

This category comprises software for connecting and controlling IoT devices at the periphery.


This operating system simplifies the programming, deployment, connection, and protection of low-power peripherals (sensors, trackers, etc.). It offers substantial software libraries to link simple devices to more powerful ones on edge and in the cloud.

AWS IoT Greengrass

The service enables peripherals to work locally with the data they create while using the cloud to manage, analyze, and securely store data. AWS IoT Greengrass runs on a wide range of devices, from server-side to Raspberry Pi.

Connectivity and control services

The platform also offers tools for monitoring and maintaining the health and safety of a fleet of devices.

AWS IoT Core

That is an underlying Amazon and IoT service that attaches all connected devices to the Amazon cloud. It is robust enough to handle myriads of device connections and reliably secure messaging and data exchange. If needed, Amazon IoT Core can extend the functionality of your IoT system with extra services like AWS Lambda.

AWS IoT Device Defender

This service guards the devices against tampering or misuse through identification, authentication and authorization, and data encryption. You can configure alerts and report suspicious behavior such as DDoS attacks from a device.

AWS IoT Device Management

This service registers, monitors, and manages connected IoT devices at any scale through a web application. AWS IoT Device Management is device-independent and OS-agnostic, so you can use it to control anything from connected cars to microcontrollers in other systems.

Analytics services

Amazon IoT eliminates infrastructure requirements by providing an infrastructure-as-a-service solution for enterprises to process and analyze IoT data.

AWS IoT Analytics

It is a wholly managed service that filters, modify, and enriches streaming IoT data in real-time. It accumulates data in a data warehouse for analysis using the built-in SQL query engine and performs sophisticated analytics such as machine learning inference.

AWS IoT Site Wise

With this AWS solution, you can simplify the gathering and routing multi-format sensor data from equipment scattered over large manufacturing or industrial sites. This service assists you in organizing, managing, and carrying out performance metrics locally by affording software and other on-site computing devices.

AWS IoT Things Graph

That service presents a graphical interface for configuring interactions between web services and devices, enabling you to raise low-power applications swiftly. Devices and services are represented using models – ready-made, reusable components. Models hide basic-level characteristics such as protocols and interfaces and allow easily integrated features in complicated workflows.

AWS IoT Events

This IoT service lets you detect events from sensors and IoT applications and take pre-defined actions before loss or failure occurs. Events are data templates that identify specific circumstances, such as changes to equipment when a belt gets stuck or motion detectors that use motion signals to turn on lights and security cameras.

These are just a few examples of many AWS IoT solutions and products. You can find an extensive pool of software on AWS’s marketplace for other uses as well.

What is AWS IoT Core?

AWS is positioning the IoT Core as the “base for IoT deployment,” as it represents all the infrastructure you need to build and run your IoT projects. 

The definition of AWS IoT Core

AWS IoT Core is a specialized, feature-rich IoT cloud service that connects devices to AWS services and separate devices, ensures data security and communication, and processes device data.

When AWS IoT Core joins IoT devices to the AWS cloud, each device broadcasts its information to the device’s shadow. The shadow service responds to requests and works with the functionality of the application. This concept makes your enterprise app lightweight and reduces response times to a minimum.

The platform can securely process and route trillions of messages to AWS endpoints and other devices using Amazon Timestream, a managed AWS IoT core database service.

How does AWS IoT Core work?

AWS IoT Core does not require a single communication protocol. Your embedded, wearable, and intelligent devices can connect to AWS IoT Core via MQTT, MQTT over WebSockets, or secure HTTPS.

The AWS IoT Core Device Gateway implements secure, low-latency, two-way communications between connected things, mobile apps, and the cloud.

Amazon AWS IoT Core constantly filters and processes data conducted by connected devices. The platform redirects data to different AWS services as needed, such as Lambda, Kinesis, and others. The AWS IoT core endpoint is used to connect to services programmatically.

You can register and track things connected to AWS IoT Core or devices that will join in the future in a dedicated registry. Device shadow permits cloud and mobile apps to request data sent and send commands to devices using AWS IoT core API gateway, enabling the platform to handle interaction with machines. The diagram below depicts a basic Amazon IoT platform architecture.

  • Multiple protocol support: AWS IoT gateway supports standard WebSockets, MQTT, and HTTP 1.1 protocols.
  • Affordable code base management: AWS gives you complete low-code capabilities to run an IoT project from its inception to large-scale rollout.
Key Features and Capabilities of AWS IoT Core

How to use AWS IoT Core

Before you start working with AWS IoT Services, you need to set up an AWS account. You can skip this stage if you already have an IAM and AWS account.

Register the devices

The first stage of utilizing AWS IoT Core is device registration. In AWS IoT Core, they are called things and can be either physical or logical. In the device registry, you assign your devices to objects in AWS IoT Core. You can register one or many devices at a time. To combine devices and apply the same command simultaneously, you can create groups in the IoT device registry.

Configure and provision devices

After registration, you need to prepare your device for use. To do this, you need three resources:

  1. IoT Thing
    IoT Things are entries in the AWS IoT device registry. Each item has a unique name and set of attributes and is associated with a physical device. Things are identified by the type of thing or grouped into groups of things.
  2. X.509 certificate
    It is a digital certificate used to manage identity and security in Internet communications and computer networks. It provides the IoT Core device with the ability to authenticate and communicate with the thing. You can generate an X.509 AWS IoT core certificate or use an existing one. Then you will need to copy it.
  3. IoT policy
    For your device to communicate, you necessitate adding the IoT policy to the device certificate. This process will be quick if you only have one or more things provisioned into the IoT Core. But if there are many devices, AWS provides the ability to do this through Timely Registration (JITR) and Timely preparation (JITP). JITR enables you to set up a workflow that enrolls device certificates and automatically attaches IoT policies to them. JITP will create an IoT object and policy in AWS IoT and then attach them to things. Now your things can start working on the IoT Core!

Manage the devices

You can manage your items in the AWS IoT Core registry, where item information is stored as JSON data. AWS IoT Device Management grants you to perform batch updates, monitor deployment speed, set error thresholds, and define steady jobs to automatically update device software so that they always work with the latest version. 

You can perform a device reboot and a factory reset to restore the machine to its original settings or fix security issues.

How to Use AWS IoT Core

Device lifecycle in AWS IoT Core

  • First, you need to enter the thing (for example, a lamp) into the register.
  • The thing is then programmed to publish a set of values for its properties or states (On, Red) to the AWS IoT Core service.
  • The last state information is stored in the shade of the thing.
  • The lamp control app uses a RESTful API to query AWS IoT Core for the last passed lamp state.
  • If the state changes (for example, the lamp turns off), the app uses the RESTful API to request an update, and the framework synchronizes the desired state with the thing.
  • When the connected thing updates its state to the desired shape, the app is notified.
