Internet of things (IoT) is, perhaps, one of the fastest growing modern technologies today. It is proving to be a revolutionary technology, opening a new world of innovation and possibilities that were unimaginable a generation ago.
The rapid development of IoT has connected almost everything to the internet. Today, the devices, appliances, and infrastructure can be controlled from anywhere by just using electronic devices.
What is Internet of Things (IoT)?
Simply put, IoT is the technology that connects ‘things’ to the ‘internet’. These things or devices can be anything from smartphones, washing machines, lamps, refrigerators, headphones, air conditioners, and almost everything that you can think of. IoT services can also be applied to machines, like jet engines in airplanes.
Analyst firm Gartner predicts that there will be more than $20 billion connected devices all over the world by 2020. This shows a very high growth in the number of IoT devices in the coming years, which will impact the way humans live and the way they work.
With a rise in the number of connected devices and their applications, the demand for IoT developers is increasing. The devices and infrastructure powered by IoT help in reducing the costs and enable new business models.
The most exciting IoT projects that are currently in high demand include smart homes, smart buildings, smart infrastructure, smart retail, self-driving vehicles, etc.
To develop an IoT project, the developers need to use IoT SDKs or IoT software development kits. These SDKs enable them to write a program for connected devices and add the required features to them.
Since there are several IoT cloud platforms out there, the developers sometimes find it difficult to choose the best IoT platform for the specific task in hand. To help you find the best IoT services’ provider in the market, we have compared the top IoT services, which will narrow your search.
Comparison of top IoT platforms
1. Amazon Web Services (AWS)
Amazon Web Services (AWS), the public cloud leader, has been putting a lot of efforts into cloud computing, artificial intelligence (AI), and IoT for a long time now. It provides IoT services through its AWS IoT platform, which comes with a broad set of tools.
AWS IoT offers a comprehensive set of IoT solutions that span edge to the cloud, allowing developers to build IoT applications for most of the use cases across a broad range of devices. These solutions can include local data collection and analysis, devices, and cloud services to store and analyze device data.
AWS IoT solutions are targeted for both – edge software and cloud services. Edge software allows developers to connect devices, collect data, and make intelligent decisions even when there is no internet connection. Whereas, the cloud services enable them to securely connect a group of devices, maintain their health, keep them secure, and detect, and respond to actions across IoT apps and sensors.
The public cloud giant has built its IoT platform on AWS cloud which is used across 190 countries. For smoother and faster development of IoT applications, the platform allows developers to connect devices and web services using a simple drag-and-drop interface.
To build smarter and intelligent IoT applications, the AWS IoT brings together AI and IoT. It helps in analyzing data and develop classy machine learning models.
On the security front, AWS IoT comes with preventative security mechanisms like device identity and authentication, encryption, and access control to device data.
Additionally, it provides a service that allows rapid monitoring and auditing of security configurations. It helps in complying the IoT apps with security best practices.

Google is among the top IoT platform providers around the world, making it easier for developers to build connected devices. The search engine giant provides Cloud IoT Core as its flagship IoT solution for creating secure and innovative solutions.
Cloud IoT Core
Google’s Cloud IoT Core is a managed solution to connect, manage, and consume data from numerous connected devices. It offers a complete solution to developers, allowing them to collect, process, analyze, and visualize IoT data in real time for supporting better operational efficiency.
Cloud IoT Core comes integrated with Google Cloud data analytics services. It enables the use of IoT data stream for advanced analytics, visualizations, machine learning, etc. As a result, it becomes easier to anticipate problems, improve efficiency, and develop rich models that can optimize business processes.
Further, this service supports standard protocols like MQTT (Message Queuing Telemetry Transport) and HTTP (Hypertext Transfer Protocol). This allows developers to use their existing devices with minimal firmware changes.
Since Cloud IoT Core runs on the serverless infrastructure of Google, it scales automatically in real time when any changes are made.
Additionally, Cloud IoT Core comes with Cloud IoT provisioning service to simplify the provisioning of devices and onboarding experience for customers and OEMs. For provisioning, it leverages tamper-resistant hardware-based security so that millions of devices can be provisioned without human intervention.
Features of Cloud IoT Core
There are two main features of Cloud IoT Core: a device manager and a protocol bridge.
It allows configuration and management of individual connected devices in a secure and coarse-grained manner. The device manager identifies the device and offers a mechanism to authenticate it during connectivity. Users can use the device manager to remotely control the device from the cloud.
The role of the protocol bridge is to provide connection endpoints for protocols and automate load balancing for all the connections. With native support for MQTT and HTTP, it publishes the telemetry of the device to Cloud Pub/Sub.
Pricing (Cloud IoT Core):
|Tier||Price||Data Volume (Per month)|
|$0.0045 per MB||250MB to 250GB|
|Standard||$0.0020 per MB||250GB to 5TB|
|$0.00045 per MB||5TB and above|

Azure IoT Edge
Azure IoT Edge is a fully managed service that deploys and runs artificial intelligence, Azure services, and custom logic right on edge devices.
IoT Edge is targeted for edge computing, as the data from edge devices need to be computed locally at the device itself, or it will become useless. This service provides the lowest latency possible between the data and the decision.
It also allows containerization of Azure Cognitive Services, Machine Learning, Stream Analytics, and Functions, and then run them locally on devices from a Raspberry Pi. The management of edge devices and applications can be done using Azure IoT Hub.
Pricing (Azure IoT Edge):
Azure IoT Edge is a free service, but to securely manage connected devices, it requires Azure IoT Hub.
