Planning A Seamless Migration To AWS IoT Core From Google Cloud IoT Core

The Internet of Things (IoT) ecosystem has evolved rapidly in the past decade with a tremendous increase in the number of IoT-connected devices and data sets. This has resulted in a shift for some customers as they look to upgrade their solutions to meet their business requirements better or transition away from less reliable or scalable platforms.

Over the years, Amazon Web Services (AWS) has helped customers like Belkin, LG, BISSELL, and Traeger Grills quickly migrate from their third-party IoT platforms to AWS IoT to enjoy improved services, better technical support, cost efficiencies, and more.

Pick an IoT-based product and you will find that it can monitor multiple devices, perform hot and cold path analytics, send or receive telemetry data, store or display the data using insights, and send event-based notifications when a particular event occurs.

An IoT device comprises the following features:

• Data storage, processing, and analysis
• Network connectivity
• IoT Sensors

With AWS, one can engineer IoT-based solutions and provide functionalities such as scalability, device maintenance, device monitoring from a single place, and so on. Besides, Amazon can create, manage, and perform several operations on the IoT devices on the cloud.

AWS is Amazon’s cloud computing platform that offers a mix of packaged Software as a Service (SaaS), Infrastructure as a Service (IaaS), and Platform as a Service (PaaS).

It was launched in 2006 to handle online retail operations and has since moved on to high-grade technology, such as the Internet of Things (IoT). Let us take a look at AWS IoT and IoT Core and what it takes to migrate from the latter to the former:

Overview of AWS IoT Core

A managed cloud platform, Amazon IoT Core enables connected devices to effortlessly and securely communicate amongst themselves and with cloud applications. With the ability to accommodate trillions of messages and billions of devices, Amazon IoT Core can reliably process and route messages to other devices and endpoints of Amazon Web Services. 

Your apps can monitor and communicate with all of your devices using Amazon IoT. AWS IoT Core is undoubtedly the best among today's cloud integration technologies. AWS, which currently holds a 37% value share in the software market, was recognized as the Best Consumer IoT Solution in 2020 for its effectiveness and dependability.

The Amazon Web Services IoT platform combines more than 200 full-featured services to support projects of any complexity and scale. It is excellent at coordinating networks, connecting billions of devices to the cloud, and securing data.

Owing to its excellent services, the platform is utilized globally by industry giants including Volkswagen, Honda, Siemens, Phillips, LG, and Carrier. It is a favorite among forward-thinking startups and government organizations.

Google's announcement to discontinue IoT Core services in 2023

Competitors to Google Cloud, including Microsoft and Amazon Web Services, provide comparable IoT services. Customers have time till August 2023 to select a new IoT provider as Google Cloud has stated it will discontinue its IoT services.

According to an update from the Google Cloud IoT Core product team, the service would end on August 16, 2023; meaning access to the IoT Core Device Manager APIs would also be discontinued.

The company has requested customers to switch from IoT Core to another service. In its note, to customers, the company says "We recommend that you take action early to migrate from IoT Core to an alternative service. As an initial step, connect with your Google Cloud account manager if you have questions about your migration plans.”

How does Amazon IoT Core work

Many internet-connected objects like sensors, embedded systems, and software use AWS Cloud to connect and interact. IoT applications gather data, process it, and transmit JSON-format messages on MQTT topics.

When a device is upgraded, every MQTT may track it. When a message is sent over an MQTT topic, it is forwarded to the MQTT message broker, who then distributes it to users who have subscribed to that subject.

Through X.509 certificates, the communication between AWS IoT and internet-connected devices is protected. To communicate with an AWS IoT device, you must first copy the AWS IoT certificate onto your device where it will serve as a credential.

The register must contain information on every device linked by AWS IoT. The registry typically contains all the information about the certificates needed to work effectively with AWS IoT, such as calling a Lambda function or editing, updating, or deleting a DynamoDB table.

Rules can be created to filter messages and carry out the desired action. The rules engine initiates the action based on the attributes when a specific rule matches the message. Additionally, it has an IAM role that gives AWS IoT access to the resources needed to do the required activity.

Devices can connect to the AWS cloud with the help of AWS IoT. The communication channels that IoT supports are:

• MQTT stands for MQ Telemetry Transport, a simple and lightweight protocol for low-bandwidth devices with unreliable networks. It is made to use less network consumption and fewer resources, which ensures stability and effective message delivery. This supposition benefits machine-to-machine (M2M) and mobile applications where there is high-quality bandwidth.
• The TLS protocol provides a channel for client-server applications to communicate over a network designed to prevent problems like tampering. However, because protocols can function without a TSL, the client must inform the server to establish a TLS connection.

Two approaches are possible for securing a TLS connection. One method is to use a unique port number. The second approach involves using a protocol feature that enables the client to request that the server converts to a TLS connection.
