CMS on AWS is more than just a provisioning tool; it's a comprehensive platform that registers vehicles as AWS IoT Core 'things', helping you securely monitor their status, certificates, and associated policies. It streamlines the critical process of onboarding vehicles into your digital ecosystem, ensuring they are ready to send and receive data securely and efficiently. By leveraging the power and scalability of Amazon Web Services, this solution provides an unparalleled foundation for your automotive cloud strategy.

Key Features of CMS on AWS

The CMS on AWS solution is engineered with a suite of features that address the multifaceted requirements of connected vehicle management. Each component is designed to enhance efficiency, security, and scalability.

Modular Design for Flexibility

One of the cornerstone benefits of CMS on AWS is its modular design. This architectural choice significantly simplifies the maintenance and implementation of the solution. By separating concerns and defining clear boundaries between functional sets, it allows the system to flexibly adapt to the dynamic demands of connected vehicle systems. Furthermore, this modularity empowers users to interchange CMS on AWS modules with bespoke implementations that adhere to defined standards, or even integrate additional custom modules. These custom additions can then be deployed seamlessly from the same central portal, ensuring a unified management experience.

Automotive Cloud Developer Portal (ACDP)

Deploying a complex, modular system requires a highly defined and streamlined method for selecting, configuring, and deploying each module. The Automotive Cloud Developer Portal, powered by Backstage, AWS CodeBuild, and AWS CloudFormation, serves this exact purpose. It provides a centralised hub for managing all CMS on AWS modules. Utilising well-defined templates, the ACDP also facilitates the integration and deployment of custom modules, ensuring a consistent and efficient deployment workflow across your entire connected vehicle landscape.

Multi-Account Multi-Region Deployments

For global automotive operations, the ability to deploy across multiple AWS accounts and regions is paramount. The ACDP offers an optional feature that enables users to deploy modules through Backstage into various AWS accounts and regions. This means you can select target accounts and regions at the point of deployment, ensuring your infrastructure is geographically distributed for resilience and latency optimisation. This feature is seamlessly supported by AWS Control Tower, demanding a sophisticated deployment structure to manage cross-account authorisation securely.

Centralised Configuration Management

CMS on AWS includes a robust mechanism to associate deployments of its modules with a unique ID. Modules sharing the same unique ID also share underlying infrastructure components, such as Virtual Private Clouds (VPCs) and Identity Providers (IdPs). This shared configuration simplifies management and ensures consistency. Additionally, a dedicated configuration module handles anonymised metrics collection, reporting usage based on Amazon Simple Storage Service (Amazon S3) and Amazon Timestream, providing valuable insights into system performance and resource consumption.

OAuth 2.0 Authentication

Security is paramount in connected vehicle ecosystems. CMS on AWS provides a default deployment of authentication infrastructure, typically leveraging Amazon Cognito, or offers the flexibility to integrate with a customer's existing IdP services. The chosen IdP is used for both CMS on AWS users and services to authenticate, retrieving access tokens and JSON Web Tokens (JWTs). The solution then provides the necessary mechanisms to validate the integrity of these access tokens with the chosen IdP, ensuring secure access to resources. This IdP is also utilised to authenticate users signing into the Backstage portal.

Role-Based Access Control (RBAC) Authorisation

Alongside strong authentication, CMS on AWS incorporates robust authorisation through its ACDP / Backstage deployment. This includes default protection for all parts of the Backstage system, even for authenticated users. Permissions, defined by Backstage and plugin creators, can be granted to users to access specific parts of the frontend and backend APIs. These permissions are logically grouped into roles, which can then be assigned to individual users and groups via a user-friendly interface. While advanced user and group creation management is continually evolving, any authenticated user successfully signing into the Backstage portal will have a user profile created, ready for authorisation permissions.

Comprehensive Network Security

CMS on AWS ensures a highly available and secure cloud network by providing either a default VPC or the option to integrate your own existing VPC. The default VPC is meticulously designed with public, private, and isolated subnets distributed across two Availability Zones (AZs). This multi-AZ architecture enhances resilience and ensures continuous operation. Modules within the solution then intelligently utilise these subnets to manage their security requirements, isolating critical components and traffic as needed.

Advanced Vehicle Provisioning

At the heart of the solution lies its advanced fleet provisioning capabilities. Vehicle provisioning begins with registering a claim certificate, automatically generated during deployment. This claim certificate incorporates a provisioning template that orchestrates the creation of AWS IoT Core things, certificates, and policies. Once the claim certificate is registered, the solution provisions each vehicle with a unique individual certificate and a public/private key pair. This allows for secure and repeated connections in the future, establishing a trusted identity for every vehicle in your fleet.

Efficient Storage and Data Management

The solution provides a straightforward yet powerful storage mechanism for both simulated and provisioned vehicle data, primarily utilising Amazon S3. It ingests data from pre-defined Message Queuing Telemetry Transport (MQTT) topics and stores it in both JSON and Parquet data formats, optimising for analytical workloads. This storage is seamlessly integrated with an alerts mechanism powered by Amazon Simple Notification Service (Amazon SNS), ensuring timely notifications based on data events.

Powerful API for Data Access

CMS on AWS offers a robust API, built on AWS AppSync GraphQL, which enables querying of vehicle data stored within the solution. This API allows for seamless integration with other CMS modules or customer-built applications. It intelligently builds and runs Amazon Athena queries, providing near real-time data directly from the CMS on AWS data lake (an Amazon S3 bucket). This provides developers and data scientists with immediate access to critical vehicle telemetry and status information.

Customisable Alerting System

Beyond data storage and access, CMS on AWS provides flexible alerting capabilities. Users can configure customisable subscriptions through AWS AppSync GraphQL API operations and Amazon SNS. These alerts can be triggered by events from other CMS on AWS modules and delivered to the user via configurable notification settings, ensuring that critical events, such as system anomalies or maintenance requirements, are promptly communicated.

Electric Vehicle Battery Health Monitoring

Recognising the growing importance of electric vehicles, CMS on AWS includes dedicated functionality for monitoring EV battery health. It provides the ability to visualise Electric Vehicle (EV) battery telemetry data and configure alerts based on predefined data thresholds. This is achieved through an integration with Amazon Managed Grafana, providing intuitive dashboards. EV battery telemetry data is efficiently obtained by running Amazon Athena queries through the CMS API module, ensuring accurate and up-to-date insights.

Vehicle Telemetry Simulation

For both developers and customers, having a reliable method for generating simulated vehicle telemetry data is crucial for testing and development. CMS on AWS offers a robust simulation capability, allowing the generation of data for up to 10 vehicles concurrently. Users can configure parameters such as data generation interval, amount, and duration, and even define a customisable schema for the generated payload. This feature accelerates development cycles and allows for comprehensive testing of the solution in various scenarios.

Integrated Metric and Cost Monitoring

To ensure operational transparency and cost efficiency, the solution includes a Service Catalog AppRegistry resource. This registers the solution’s CloudFormation template and its underlying resources as an application in both Service Catalog AppRegistry and Application Manager. This integration enables users to view the solution in 'myApplications' – an extension of the AWS Management Console home. From here, you can centrally manage the solution’s resources, perform application searches, generate reports, and execute management actions. Crucially, you can view metrics such as the overall deployment cost and set up additional monitoring with services like AWS Cost Explorer, Amazon CloudWatch, and AWS Security Hub.

Advanced Predictive Maintenance

CMS on AWS offers a sophisticated MLOps (Machine Learning Operations) infrastructure for predictive maintenance. This capability allows for the training, retraining, evaluation, and deployment of ML models specifically for fault prediction use cases. Users can run both real-time and batch inference on deployed ML models to identify potential issues before they escalate. Furthermore, CMS on AWS provides a generative artificial intelligence (AI) agent that can answer natural language queries regarding the fleet, leveraging textual data stored in an S3 bucket and querying the backend for real-time vehicle maintenance status.

Intuitive Fleet Management UI

To provide an accessible and comprehensive overview, CMS on AWS includes a user interface that facilitates the management of vehicles and fleets within AWS IoT FleetWise. This UI offers the capability to build and insert custom widgets, allowing for real-time monitoring of your fleet and individual vehicles via captured telemetry data. This visual interface enhances operational awareness and decision-making.

How AWS IoT Core Facilitates Vehicle Control and Data Management

The capabilities of CMS on AWS are deeply intertwined with the broader AWS Connected Vehicle Reference Architecture, particularly leveraging AWS IoT Core as its foundational communication and management layer. Understanding how AWS IoT Core interacts with vehicles provides deeper insight into the robustness of the CMS solution.

Modernising Vehicle Communication

AWS IoT Core and MQTT5 are central to modernising communication workflows, enabling efficient data gathering, collection, and distribution with connected vehicle workloads. In-vehicle devices, each with a unique identity (X.509 certificate), securely publish telemetry data to AWS IoT Core using the MQTT protocol, secured with mutual TLS (mTLS). To minimise in-vehicle software complexity, only essential libraries for AWS IoT Core connectivity are implemented. Features like shared subscriptions allow client workers to process data payloads from millions of vehicles by load balancing across topics, ensuring high throughput. Topic aliases further reduce payload size over cellular connections, saving power and cost. Amazon Elastic Container Service (Amazon ECS) then decodes, processes, and persists this telemetry data, offering the scalability needed to handle message peaks without bottlenecks. For remote commands, the request/response messaging pattern in AWS IoT Core tracks asynchronous client requests, allowing commands submitted via interfaces (e.g., built with AWS Amplify and Amazon API Gateway) to be persisted in Amazon DynamoDB and delivered to the device. Features like Message Expiry provide flexible control over command delivery, and Retained Messages ensure critical OEM commands are available even when a vehicle comes back online.

Data Ingestion, Processing, and Analysis

The connected vehicle, acting as an IoT device, uses its sensors to collect data. The AWS IoT FleetWise Edge Agent communicates with the vehicle’s network, decoding signals and sending data payloads through AWS IoT Core as defined by data campaigns. With AWS IoT FleetWise, organisations maintain full data ownership and control. Amazon Route 53 can be used with AWS IoT Core to choose an AWS Region based on geo-location or latency for optimal connectivity. Devices can be automatically registered upon their first connection to AWS IoT Core, with an AWS Lambda function validating the gateway and creating the IoT thing, policy, and certificate. Data collected via AWS IoT FleetWise is sent to Amazon Timestream or Amazon S3 for storage. This data fuels advanced analytics with Amazon SageMaker for improving ADAS/AV models and optimising vehicle design, and Amazon QuickSight for continuous improvement in vehicle quality, safety, and autonomy. AWS IoT Core Device Shadow makes a vehicle’s state available to applications whether the device is connected or not, providing a built-in mechanism to update the vehicle's state from the cloud. AWS IoT Device Management supports over-the-air (OTA) management through IoT jobs and fleet indexing for managing device state, connectivity, and violations.

Secure Certificate Lifecycle Management

Security in connected vehicles relies heavily on robust certificate management. CMS on AWS, leveraging AWS Private Certificate Authority (AWS Private CA), facilitates a secure operational certificate lifecycle. A subordinate CA is created in AWS Private CA and registered with AWS IoT Core. The Electronic Control Unit (ECU) generates a private key and Certificate Signing Request (CSR), authenticating to a certificate broker using an existing attestation certificate. The broker issues the operational certificate via AWS Private CA. When the ECU connects to AWS IoT Core using TLS with this certificate, AWS IoT Core validates it. An IoT rule on a reserved MQTT topic then invokes a Lambda registration function to implement custom logic, such as creating an AWS IoT Core policy specific to the ECU, performing custom authentication (e.g., OCSP checks), and changing the certificate status to active. AWS IoT Device Defender continuously monitors for audit findings like expiring or revoked certificates, sending them to AWS Security Hub. EventBridge can then initiate workflows (e.g., AWS Step Functions) to orchestrate certificate rotation, ensuring continuous security and compliance.

Robust Encryption and Security Monitoring

Encryption and monitoring are integral to vehicle security. ECUs publish telemetry using MQTT to AWS IoT Core. During the TLS handshake, AWS IoT Core validates the client certificate and authorises operations based on policies attached to the certificate and thing groups. AWS Key Management Service (AWS KMS) allows for the creation, management, and control of cryptographic keys, enabling encryption at rest for all services and optional client-side encryption for highly sensitive payload data. AWS IoT Device Defender monitors devices for abnormal behaviour, detecting anomalies like unusual rates of authorisation failures or anomalous traffic flow. Findings are sent to AWS Security Hub, which aggregates and normalises security alerts from various AWS services. EventBridge then routes these findings to remediation workflows, allowing for automated responses such as modifying IoT policies or disconnecting an ECU if suspicious activity is detected.

Building Companion Applications

AWS IoT Core also underpins the development of companion applications for vehicle control. A vehicle establishes an MQTT connection to AWS IoT Core and subscribes to control plane request topics. AWS IoT Core publishes the vehicle’s connected state to lifecycle events topics. Using AWS Amplify, a remote command can be sent by a secure WebSocket as a mutation to AWS AppSync, persisted to DynamoDB, and processed by Lambda. If the vehicle is connected, Lambda publishes the command payload to the request topic. If disconnected, Lambda can send an SMS via Amazon SNS to wake up the vehicle to receive the command. Upon command receipt, the device logic processes it and publishes the result back to a response topic, which is then processed by AWS AppSync and persisted to DynamoDB. AppSync then alerts companion applications with the updated vehicle state, providing real-time feedback to users. Static assets for companion applications can be distributed efficiently using Amazon S3 and Amazon CloudFront.
