Announcement of Google IoT Core retirement, prompting search for alternatives like AWS IoT Core and Azure IoT Hub.


As of August 16, 2023, Google has made an official announcement that its IoT Core service, which was introduced in 2017 as an entry into the competitive market of the Internet of Things (IoT), will be retired. After about five years in operation, Google has decided to discontinue the IoT Core service, notifying its customers in August of the previous year, leaving them with the task of finding alternative solutions. A comparison of Google's IoT portfolio with that of its direct competitors, such as Microsoft Azure or Amazon Web Services (AWS), reveals that the offerings in Azure and AWS are more extensive.

Alternatives To Google IoT Core Services

Google's current IoT core services can be substituted with comparable alternatives like AWS IoT Core or Azure IoT Hub. These services not only serve as replacements for Google's existing IoT offerings but also provide more comprehensive features. Let us discuss AWS IoT core and Azure IoT Hub along with its benefits in detail.

Whether it's MQTT, HTTPS, MQTT over WSS, or LoRaWAN, AWS IoT Core provides comprehensive solutions. This flexibility ensures smooth and efficient data exchange between your devices and the cloud.

Security is paramount, and AWS IoT Core takes it seriously. The service provides mutual authentication and end-to-end encryption, safeguarding your device connections and data from potential threats or unauthorized access. Rest easy knowing that your valuable information is protected at all times.

Additionally, AWS IoT Core empowers you to make real-time decisions based on your business rules. You can effortlessly filter, transform, and act upon device data on the fly. This capability allows you to extract valuable insights and take timely actions to optimize your operations and drive business growth.

Benefits of AWS IoT Core

Serverless Management

Unlike traditional setups, AWS IoT Core eliminates the need for provisioning or managing servers. This serverless approach allows you to focus on your IoT applications and business logic without worrying about the underlying infrastructure, leading to increased agility and reduced operational overhead.


AWS is known for its ability to scale effortlessly, and the same applies to AWS IoT Core. As your IoT fleet grows, AWS IoT Core can handle the increased workload, ensuring a smooth experience for both device connectivity and data processing.

Real-time Data Processing

AWS IoT Core enables you to filter, transform, and act upon device data in real time based on your defined business rules. This capability empowers you to make timely decisions, trigger actions, and gain valuable insights from the data generated by your devices.

Robust Security Features

Security is a top priority in IoT deployments, and AWS IoT Core offers advanced security features to protect your devices and data. With mutual authentication and end-to-end encryption, you can establish secure device connections, safeguarding against unauthorized access and data breaches.

Reliability and High Availability

AWS is designed with high availability and reliability in mind. With multiple data centers and built-in redundancy, AWS IoT Core ensures that your IoT infrastructure remains accessible and operational, even in the face of failures or outages.

2. What is Azure IoT Hub?

Microsoft Azure IoT Hub is a cloud-based solution designed to connect, monitor, and manage billions of Internet of Things (IoT) assets securely and reliably. It ensures a strong communication channel for data exchange between IoT applications and devices, keeping information confidential through individual device authentication.

One notable feature is Device Update for IoT Hub, enabling over-the-air updates for IoT devices, enhancing security, and facilitating rapid responses to threats. It simplifies device provisioning, allowing the registration and management of IoT devices with ease.

Azure IoT Hub enables bidirectional communication, with device-to-cloud telemetry data, providing insights into device states, and cloud-to-device messaging, enabling reliable command delivery and tracking.

The platform integrates seamlessly with Azure Event Grid using serverless computing or on prem-compute architecture, streamlining IoT application development. Additionally, it extends capabilities to the edge through IoT Edge modules, distributing intelligence, including AI and analytics, while reducing costs and supporting offline or intermittent connectivity.

Benefits of Azure IoT Hub

Enhanced Security

Azure IoT Hub provides robust security features, including per-device authentication and individual identities for connected devices. This ensures that only authorized devices can access your IoT application and its data, reducing the risk of unauthorized access and data breaches.

Device Update Management

With Device Update for IoT Hub, you can perform over-the-air updates for your IoT devices, keeping them up-to-date and secure. This feature allows you to respond rapidly to security threats and deploy new features without the need for additional development and maintenance costs.

Scalable Provisioning

Azure IoT Hub's device provisioning service allows for zero-touch registration and provisioning of devices, making IoT deployment faster and more efficient. It supports a wide range of IoT devices compatible with IoT Hub, ensuring scalability as your IoT network grows.

Full Integration with Azure Services

Azure IoT Hub seamlessly integrates with other Azure services such as Azure Event Grid and serverless computing. This integration simplifies IoT application development and enables you to build sophisticated applications by leveraging the power of the cloud.

Cost Efficiency

By leveraging Azure's cloud-hosted solution, you can reduce the costs associated with running and maintaining IoT applications. Additionally, the ability to distribute intelligence to edge devices can help optimize costs and streamline development efforts.
