Building a scalable and secure IoT solution can be challenging, particularly when it comes to managing large volumes of data, ensuring device security and maintaining reliable connectivity. Amazon Web Series (AWS), a Cloud computing platform, looks to address all of these challenges.
AWS offers a range of Cloud services designed to enable enterprises, developers and individuals to build, deploy and manage applications and services without the need for physical hardware. Examples of how the AWS is deployed can be seen in a collaboration between BICS and AWS earlier this year, when BICS announced it was working with the platform to launch a new, Cloud-based roaming service to provide more reliable Internet access for mobile roaming.
“Low latency combined with truly global and interactive communications has the power to unlock massive potential for connected cars, drones, AR headsets, and many more next-generation use cases, and BICS is delighted to be at the core of driving this forward with AWS,” said Jorn Vercamert, Vice President Customer Solutions and Products at BICS at the time of announcement.
Understanding AWS IoT Core
AWS offers a range of services designed to support IoT deployments from device management to data analytics and Edge computing. The key services include AWS IoT Core, AWS Greengrass and AWS Lambda.
AWS IoT Core is a managed Cloud service that allows connected devices to interact securely with Cloud applications and other devices. It acts as the central hub for IoT communications, enabling the user to connect many devices and process trillions of messages.
Key features of AWS IoT Core include device connectivity, as it supports MQTT, WebSockets, and HTTP protocols, allowing it to provide flexibility in how devices connect to the Cloud; guarantees secure communication between devices and the Cloud using authentication and encryption; a scalable message broker to ensure organised communication across the IoT network; and a rules engine to process and route messages to AWS services like Lambda, S3 and DynamoDB.
AWS Greengrass: Bringing AWS to the Edge
AWS Greengrass extends Cloud capabilities to Edge devices, which means they can act locally on the data they generate while still using the Cloud for management, analytics and storage purposes.
Edge computing capability is especially important for IoT applications that require low latency, real-time processing and operating in environments that may not necessarily have continual connectivity.
Key features of AWS Greengrass include local processing, allowing devices to run AWS Lambda functions locally without an active Internet connection; secure communication using encrypted data channels; device shadows which can synchronise the state of devices with the Cloud; and over-the-air (OTA) updates.
Best practices for integrating AWS with IoT devices
Integrating AWS with IoT devices requires considering a number of factors such as security, scalability and efficient data processing.
- Prioritise security from the start: AWS IoT Core provides security features but steps like implementing mutual authentication by ensuring all devices use mutual Transport Layer Security (TLS) and encrypting data at rest and in transit
- Design for scalability: As the IoT network grows, scalability is a critical factor. Using AWS IoT Core’s scaling features help with automatically scaling to handle the number of connected devices and the volume of messages.
- Monitor performance: Continuous monitoring and optimisation are a staple of any efficient IoT solution, using AWS IoT analytics to analyse data and gain insights into device performance and usage patterns achieves this.
Conclusion
AWS offers a scalable platform for building IoT solutions to meet the varying demands of modern industries. Taking advantage of services such as AWS IoT Core and Greengrass, enterprises can build secure and efficient IoT networks. Keeping to best practices around security, scalability and performance monitoring will allow these enterprises to fully capitalise on the benefits.
