Data serves as a vital catalyst for digital transformation and the advancement of Industry 4.0. Manufacturers can leverage data to achieve a comprehensive view of their operations, extracting actionable insights that can enhance production quality, facilitate real-time predictions, and drive cost efficiencies. Advanced Big Data analytics techniques enable capabilities in performance measurement, maintenance, and process optimization.
Manufacturers typically gather data from numerous disconnected sources, each residing in its own database, often referred to as “silos.” Accessing this data typically involves ad-hoc reporting or analytics systems, leading to increased isolation and support challenges over time. While traditional data warehouses efficiently handle structured data queries, they often fall short for unstructured or semi-structured data and may struggle to scale according to the demands of Industry 4.0.
To extract operational insights from manufacturing data, businesses are adopting an Industrial Data Platform. This blog will address the challenges associated with existing solutions and outline a resilient architecture on AWS.
Challenges with the Industrial Data Platform
Several challenges arise when collecting and analyzing industrial data:
- Data Integration: Linking data from various sources can be difficult and often requires significant enrichment and cataloging to gain meaningful insights.
- Infrequent Data Collection: Sensors may generate data regularly, but the use of ad-hoc aggregation tools may only occur sporadically, hindering real-time analysis and the application of AI/ML techniques.
- Data Accessibility Issues: Applications may exist on different networks or utilize various database engines, necessitating diverse transformation tools to prepare the data for analysis.
- Scalability and Flexibility: As more data is generated or new sources are added, operational overhead and costs can significantly increase.
Common Solutions
Data Silos
Data silos are dedicated databases, such as those for PLC data or ERP systems. As organizations evolve, they tend to create new silos, each requiring unique management and security protocols, ultimately raising operational costs and risks. There is often no comprehensive catalog to locate or access the desired data, leading to inefficiencies in analytics workloads.
Data Warehouse
An Enterprise Data Warehouse (EDW) acts as a centralized repository for structured data, receiving data from various transactional systems and databases. While it aims to address the fragmentation of data silos by consolidating data in one location, it requires careful schema management, which can become cumbersome as data needs evolve. Moreover, scaling the platform often demands adding compute, storage, and licensing, which can lead to downtime.
Functional Gaps
The existing solutions exhibit several functional gaps:
- Lack of Centralized Access: Data silos decentralize information, complicating the search, access, and analysis processes. EDWs are not optimally equipped to handle unstructured or semi-structured data, necessitating a unified platform for insights.
- Inflexibility in Data Ingestion: Comprehensive data analysis requires the integration of diverse data types, and the inability to scale appropriately can hinder this process.
- Limited Analytical Capabilities: Many silos and warehouses primarily support SQL queries, lacking the advanced analytics and machine learning functionalities needed for predictive insights.
- Disconnected Analytics: Without a central platform, analytics produced in silos may not be shared, limiting the overall value of insights.
Architectural Approach
To bridge the functional gaps in current solutions, organizations often invest time and resources in scaling existing data silos or EDWs, which can be challenging and inflexible. A shift toward an Industrial Data Platform is essential for companies transitioning to Industry 4.0, requiring accessible data from a single source, with clear cataloging to facilitate data discovery. The platform must also be adaptable to accommodate various data formats—structured, unstructured, or semi-structured.
Industrial Data Platform Overview
The diagram below represents a conceptual Industrial Data Platform on AWS.
At a high level, data is ingested from multiple sources—shop floor applications, production processes, MES systems, and enterprise applications—through various connectors, edge applications, or IT/OT blueprints tailored to specific use cases. Once the data is collected, it is centralized and processed within a unified data backbone, enabling transformation, modeling, and contextualization for downstream consumption. This layer facilitates flexible access to business insights through operational dashboards, third-party applications, and advanced analytics services. Security and automation are paramount in maintaining a robust infrastructure.
