SAT Overview

    SAT Tech

    To devise a scalable and secure data lake solution for your IoT devices using AWS, the architecture will need to support ingestion, enrichment, normalisation, and curation of data, as well as facilitate advanced analytics and model integration for behavioural insights. Additionally, the system must handle privacy requirements by anonymising data for external use by third parties.

    High-Level Architecture Overview

    The platform will consist of the following core components:

    1. Data Ingestion Layer: This layer handles ingestion of raw data from multiple IoT devices.
    2. Data Enrichment & Normalisation Layer: Here, the raw data is processed, enriched, and normalised to ensure it follows a unified schema.
    3. Data Lake Storage: A highly scalable data repository that stores the processed data in raw, enriched, and curated forms.
    4. Data Processing Layer: Responsible for running models and performing data transformations such as behavioural analysis.
    5. Anonymisation & Governance Layer: Ensures that data privacy standards are enforced, especially before external data sharing.
    6. Data Consumption Layer: Offers access to curated and anonymised data, which can be leased to third parties through API endpoints or data exchanges.
    7. Security, Compliance, and Monitoring: Safeguards and monitors the data and its access across the platform.

    Detailed Design

    1. Data Ingestion Layer

    AWS Services: IoT Core, Kinesis Data Streams, Lambda

    • AWS IoT Core: This service will connect your IoT devices to AWS. The IoT Core will handle incoming data streams from different devices and vendors.
    • AWS Kinesis Data Streams: This service will allow for the real-time ingestion of high-throughput data from the IoT Core. Since IoT devices generate continuous motion data, Kinesis is ideal for processing and buffering the data before it moves to storage.
    • AWS Lambda: A serverless service that will process incoming data, perform pre-processing (e.g., adding metadata such as timestamps), and route it to different services for further processing.

    2. Data Enrichment & Normalisation Layer

    AWS Services: Lambda, Glue, DynamoDB, Step Functions

    • AWS Lambda: Will trigger transformation and enrichment workflows as soon as new data is ingested. This could involve adding contextual metadata (e.g., location, device ID) or calculating initial statistics.
    • AWS Glue: Glue is an ETL (Extract, Transform, Load) service that will help with data normalisation. It can convert the data into a consistent format and schema, making it easier to analyse across different vendors’ devices.
    • DynamoDB (Optional): For fast lookups and managing metadata such as device configurations or user-specific information.
    • AWS Step Functions: This will orchestrate the enrichment and normalisation workflows, ensuring that data flows smoothly through the various processing stages.

    3. Data Lake Storage

    AWS Services: S3, Lake Formation

    • Amazon S3: Your data lake will be primarily built on Amazon S3. Data from IoT devices will be stored in raw format and organised into a bucket structure. After enrichment, data will be stored in a processed data bucket.
    • AWS Lake Formation: This service helps with the secure management of data lakes. It will enforce access controls on the data in S3 and enable collaboration across different teams and external companies.
    • Data Organisation: S3 Buckets will be organised in different layers:
      • Raw Data: Data as it is ingested.
      • Enriched Data: Data that has gone through enrichment and normalisation.
      • Curated Data: Data that is prepared for analysis or external consumption.

    4. Data Processing Layer

    AWS Services: SageMaker, Glue, EMR, Lambda, Redshift Spectrum

    • Amazon SageMaker: Will be used to train and deploy machine learning models that perform behavioural analysis. These models could trend and analyse data based on a subject’s age, medical condition, prognosis, etc.
    • AWS Glue/EMR: For running large-scale distributed processing and performing additional data transformations, Glue or EMR (Elastic MapReduce) could be employed. You can use Spark or Hadoop-based frameworks for parallel data processing.
    • AWS Lambda: For lightweight transformations or triggering additional downstream processes.
    • Redshift Spectrum: Allows you to run SQL queries on data stored in S3 without needing to load it into Redshift, offering near-real-time analytics on curated data.

    5. Anonymisation & Governance Layer

    AWS Services: Macie, IAM, Glue DataBrew

    • AWS Macie: This service will automatically detect and protect sensitive data, ensuring that any data that leaves the platform is anonymised. Macie can help enforce compliance with privacy regulations like GDPR.
    • Glue DataBrew: This service could be used to clean and prepare data before anonymisation. You can also automate the removal of personally identifiable information (PII) and mask sensitive information in data streams.
    • IAM Policies: Identity and Access Management policies will ensure that only authorised internal and external users have access to certain data. Strict policies will govern the use of data at all stages of the pipeline.

    6. Data Consumption Layer

    AWS Services: API Gateway, Athena, S3, Data Exchange

    • Amazon S3: Curated data can be stored in S3 buckets and made available to third parties. You can provide structured access to these datasets using pre-signed URLs or by enabling specific IAM permissions for partners.
    • API Gateway: External partners can access data through RESTful APIs, with access managed by API Gateway. API Gateway integrates well with Lambda, ensuring that requests can trigger the latest datasets.
    • AWS Data Exchange: AWS Data Exchange enables you to package, distribute, and monetise your data. Partners can subscribe to datasets directly, and you can control how often data is updated and distributed.

    7. Security, Compliance, and Monitoring

    AWS Services: CloudTrail, CloudWatch, KMS, Shield

    • AWS KMS (Key Management Service): All sensitive data will be encrypted both in transit and at rest using KMS. Encryption policies will be strictly enforced across all storage and database services.
    • AWS CloudTrail and CloudWatch: These services will provide full auditing and monitoring capabilities. All interactions with the data will be logged and monitored for compliance purposes.
    • AWS Shield: Provides DDoS protection and security monitoring for APIs and data endpoints.

    Data Flow & User Journey

    1. Ingestion: IoT devices stream raw motion data to AWS IoT Core, where it is ingested into Kinesis Streams.
    2. Processing & Enrichment: Kinesis triggers a Lambda function that enriches the data by adding metadata and ensures that it follows a unified schema. This data is then passed to Glue for further normalisation.
    3. Storage: Enriched data is stored in the Data Lake on S3. Data is separated into raw, enriched, and curated buckets for future analysis and access.
    4. Behavioural Modelling: SageMaker trains and deploys behavioural models to analyse trends in the data based on factors such as age, medical condition, and prognosis.
    5. Anonymisation: Before any external parties can access the data, Macie and DataBrew ensure that all personally identifiable information (PII) is anonymised.
    6. Monetisation & Access: External companies can lease anonymised data via AWS Data Exchange or APIs exposed through API Gateway. Access is governed by strict IAM and security policies.

    Charging Strategies and Potential Customers

    With the anonymised data now available for leasing, you can develop flexible and profitable charging strategies that appeal to a range of potential customers across various industries.

    Building a Charging Model

    When developing a charging model for the platform, consider the following key factors:

    Data & API

    Given the large volumes of data you may be handling in the integration of your predictive analytics platform with H&HI’s software, an API with high scalability and support for efficient data transfer is critical. Here’s a suggestion based on typical high-performance API considerations for large-scale data:

    1. RESTful API with Pagination and Filtering

    REST APIs are highly flexible and scalable, commonly used for integrating analytics platforms. If Honor’s platform expects to request data or analytics results in smaller chunks, you can design your API to paginate and filter results, allowing them to request only the data they need, minimizing the load.

    • Pros: Easy to implement, widely supported, lightweight.
    • Cons: Inefficiency with very large datasets due to statelessness.
    • Optimization: Use GZIP compression and pagination to reduce data transfer load. Ensure the API can handle JSON or Protobuf for serialization, both of which are compact and efficient formats.

    2. GraphQL for Dynamic Queries

    GraphQL could offer a more flexible way to query predictive analytics data, allowing Honor’s software to retrieve only the specific data fields they need at any time. This reduces data over-fetching and can improve the efficiency of large data transfers.

    • Pros: Efficient querying, flexibility, reduces network bandwidth.
    • Cons: Can be complex to implement and manage, especially with deeply nested structures or highly relational data.
    • Optimization: Implement query depth and complexity limits to avoid performance bottlenecks during large data transfers.

    3. gRPC for High-Performance Streaming

    Given the potential for large volumes of data, gRPC (Google Remote Procedure Call) might be the best solution if you’re dealing with very high-frequency, large datasets. gRPC uses HTTP/2 for transport, enabling bi-directional streaming and improved efficiency for real-time data transfers, and supports binary serialization via Protocol Buffers, which is faster and more compact than JSON or XML.

    • Pros: Highly efficient, supports streaming, better suited for large datasets, bi-directional communication.
    • Cons: More complex to set up, requires support for Protocol Buffers.
    • Optimization: Use streaming for continuous large datasets rather than multiple individual requests. This allows Honor to consume the data as it arrives, ensuring low-latency transfers.

    4. WebSockets for Real-Time Data Feeds

    If the predictive analytics data needs to be sent to Honor’s platform in real time, WebSockets could be appropriate. This will maintain an open connection for pushing updates as they are processed, rather than pulling batches of data.

    • Pros: Real-time communication, full-duplex communication.
    • Cons: Not ideal for batch data or extremely large datasets compared to gRPC or REST.

    5. Bulk Data Transfer (S3, Azure Blob Integration)

    If large batches of historical data need to be transferred at once (as opposed to streaming), consider integrating with cloud storage APIs such as AWS S3 or Azure Blob Storage. Your platform can generate predictive analytics data in bulk and upload it to cloud storage for retrieval by Honor’s platform via presigned URLs or triggers.

    • Pros: Ideal for very large datasets, cost-effective, highly scalable.
    • Cons: Requires additional infrastructure to manage and transfer files.

    Recommendation:

    For ongoing, large-scale data integration where real-time analytics and efficiency are critical, gRPC would be ideal due to its performance and streaming capabilities. For flexibility in querying, consider GraphQL alongside gRPC. For bulk transfers, supplement with cloud storage integration to handle periodic large datasets.

    REST is well-suited for delivering bulk data at scheduled intervals, assuming you’re not dealing with extreme real-time demands or massive continuous streams. Here are a few considerations to make it work efficiently:

    Key Factors for Using RESTful API:

    1. Batching Data: Since you’re exporting data twice per day, each batch can be handled by a RESTful API, especially if the data can be paginated or segmented into manageable chunks. This prevents timeouts and allows for more efficient processing of large data exports.
    2. Compression: REST APIs can benefit from compression (e.g., GZIP), significantly reducing the payload size during each transfer. This is crucial when working with large datasets from a data lake.
    3. Asynchronous Processing: If the data extraction or transformation takes time, you could set up an asynchronous REST API where Honor’s platform can make a request, get a job ID, and then poll the API periodically for the status of the export or download the file once it’s ready.
    4. Rate Limiting: Ensure that your API can handle large payloads without hitting rate limits or resource constraints. It’s best to configure rate limiting on both sides (client and server) to avoid bottlenecks.
    5. Data Format: Use an efficient data serialization format like JSON, or Protobuf if both sides can handle it. JSON is common for RESTful APIs but could introduce overhead with large datasets, so consider Protobuf for more compact data representation, reducing bandwidth usage.
    6. Security: Given that this data is sensitive and likely subject to compliance requirements, ensure you implement robust authentication, authorization (using OAuth or API keys), and encryption (TLS/HTTPS).

    Example Workflow:

    • Twice per day, your data lake processes a data export request, and the results are made available as a paginated REST API.
    • Honor’s system queries your API endpoint, fetching the new dataset.
    • If the dataset is large, the API returns partial responses (with pagination) until the full dataset is retrieved.
    • If necessary, the export process can provide status updates for long-running jobs via asynchronous calls.

    Advantages:

    • Flexibility: REST APIs are widely supported, making integration easier.
    • Efficiency: With compression, pagination, and appropriate batching, you can move large amounts of data efficiently.
    • Scalability: REST APIs can scale with the appropriate infrastructure, allowing for future growth in data volume.

    In summary, if the data exports occur in defined intervals (e.g., twice per day), a well-architected REST API with support for compression, pagination, and asynchronous job handling should be sufficient.

    Data Transfer

    When considering whether to initiate the data transfer to Honor or have them request it, both approaches have advantages depending on the technical and operational context of the integration.

    Option 1: Honor Requests the Data (Pull Model)

    In this model, Honor’s system would initiate the request to pull data from your RESTful API at scheduled times (e.g., twice a day). This approach is often more flexible, allowing Honor to control the timing and frequency of data requests.

    Advantages:

    • Control: Honor can control when they need the data and can scale their requests according to their system’s capacity.
    • Error handling: If there’s a failure during data transfer, Honor’s system can re-attempt the request.

    Implementation:

    • You would expose an API endpoint, and Honor’s system would request data at predefined intervals.
    • Data could be paginated or provided in chunks, depending on the size.

    Best Practices:

    • Implement authentication (OAuth2, API keys) to ensure only authorized parties can request the data.
    • Use rate limiting to prevent overloading your system with requests if Honor’s system retries too frequently.

    Option 2: Your System Initiates the Transfer (Push Model)

    In the push model, your system would initiate the transfer of data to Honor’s system at the predefined intervals. You would send the data directly to an API endpoint provided by Honor.

    Advantages:

    • Control: You maintain control over when data is sent and ensure that it happens at the exact times you prefer.
    • Error Handling: You can build internal retries and failure-handling mechanisms within your system if the data transfer fails.

    Implementation:

    • You would set up a job that processes and pushes data to Honor’s API endpoint at scheduled times.
    • You might need to handle API responses from Honor, ensuring successful delivery and handling failures gracefully.

    Best Practices:

    • Ensure that H&HI’s system is available and can handle incoming data. This can be done through handshake mechanisms or by checking the status of their system before initiating the transfer.
    • Set up monitoring and alerts to track the success of each data push and to automatically retry in case of failures.

    Choosing the Right Approach:

    1. Pull Model (H&HI Requests Data): This is often preferred when the receiving system needs flexibility in managing when and how they ingest data. If their system is built to periodically request updates from various sources, this may be the more seamless approach.
    2. Push Model (You Send Data to H&HI): If you want to control the data flow more tightly or if their system isn’t set up to handle requests on a scheduled basis, pushing the data may be better. It also ensures that the data transfer occurs at precise intervals, and you have full control over retries and error handling.

    Recommendation:

    You may want to discuss this with H&HI’s technical team to see which model aligns better with their current architecture. If their system is designed to query external APIs at regular intervals, the pull model would work well. If they prefer receiving data at scheduled intervals without needing to manage those requests, then the push model would be more suitable.

    In either case, ensure that robust mechanisms for error handling, retries, and monitoring are in place to handle potential issues with large data transfers.
