AWS has vastly enhanced its IoT suite of services, ever since its first inception towards the end of 2015. Here is a brief explanation of what it offers:

• AWS IoT Core: The AWS IoT Core is a managed service that allows you to securely connect and interact with billions of IoT devices, without having to bother about setting up or managing any underlying infrastructure. You can use the IoT Core service to build IoT applications, using a combination of various AWS services as well, such as AWS Lambda, Amazon Elasticsearch, Amazon machine learning, and so on.
• AWS IoT Device Management: The AWS IoT Device Management service allows you to register, organize, and manage a large number of IoT devices, easily. You can use this service to on-board devices in bulk and then manage them all, using a single pane of glass view.
• AWS Greengrass: AWS Greengrass is a software service designed to execute Lambda functions locally, on your IoT devices. In addition to this, you can also use Greengrass to sync data between the device and the IoT Core, using data caching along with other functionalities, such as ML inference, messaging, and so on.
• AWS IoT Analytics: Connecting and managing billions of IoT devices is one task, and querying the large IoT data set is quite another. AWS IoT Analytics is a completely managed service that allows you to run analytics on extremely large volumes of IoT data, without having to configure or manage an underlying analytics platform. Using this service, you obtain better insights on your devices, as well as build resilient IoT applications.
• AWS IoT Button: The AWS IoT Button is a Wi-Fi enabled, programmable button which enables you to write and integrate an IoT application, without having to know about any device-specific code.
• AWS IoT Device Defender: With so many devices to manage and maintain, it is equally important to safeguard the devices against malicious attacks. AWS IoT Device Defender is a managed service that allows you to secure, manage, and audit remote devices against a set of security rules and policies. If any deviations are found, IoT Device Defender triggers appropriate notifications for them.
• Amazon FreeRTOS: Amazon FreeRTOS is a custom operating system built specifically for small, low-powered edge devices or microcontrollers. The operating system is based on the FreeRTOS kernel and helps to easily connect and manage devices with the AWS IoT service.

With this, we come to the end of this section. In the next section, we will learn a bit about the AWS IoT Core service in detail, along with a simple and easy-to-follow getting started guide.
