ScaleOut Software announces a preview of its forthcoming cloud service for streaming analytics using the real-time digital twin model. It’s called the ScaleOut Digital Twin Streaming Service™, and it’s now available for a limited number of users to explore and provide feedback. Sign up to use the service here.
A major challenge for stream-processing applications that track numerous data sources in real time is to analyze telemetry relevant to each specific data source and combine this with dynamic, contextual information about the data source to enable immediate action when necessary. For example, heart-rate telemetry from a smart watch cannot be effectively evaluated in isolation. Instead, it needs to be combined with knowledge of person’s age, health, medications, and activity to determine when an alert should be generated.
A second and equally daunting challenge for live systems is to maintain real-time situational awareness about the state of all data sources so that strategic responses can be implemented, especially when a rapid sequence of events is unfolding. Whether it’s a rental car fleet with 100K vehicles on the road or a power grid with 40K nodes subject to outages, system managers need to quickly identify the scope of emerging problems and rapidly focus resources where most needed.
Traditional platforms for streaming analytics attempt to look at the entire telemetry pipeline using techniques such as SQL query to uncover and act on patterns of interest. But this approach is complex and leads to superficial analysis in real time, forcing telemetry to be logged into a data lake for later analysis using Spark or other tools. How do you trigger an alert to the wearer of a smart watch at the exact moment that the combination of telemetry fluctuations and knowledge about the individual’s health indicate that an alert is needed?
In addition, because real-time digital twins maintain and dynamically update key information about each data source, aggregate analytics — essentially, continuous queries — can continuously look for patterns in this curated data instead of in just the raw telemetry. This enables immediate, focused insights that enhance situational awareness.
The ScaleOut Digital Twin Streaming Service plugs into popular event hubs, such as Azure IoT Hub, AWS IoT Core, and Kafka, to extract event messages and forward them to real-time digital twin instances, one for each data source. It then triggers application code to process the messages and gives it immediate access to memory-based contextual information for the data source. Application code can generate alerts, command devices, update the contextual information, and read or update databases as needed. This code can be thought of as similar to a serverless function with the major distinction that it is automatically supplied contextual information and does not have to maintain it in an external data store.
This highly scalable cloud service is designed to simultaneously and cost-effectively track telemetry from millions of data sources and provide real-time feedback in milliseconds while simultaneously performing continuous, aggregate analytics every few seconds. A powerful UI enables fast deployment of real-time digital twin models created using the ScaleOut Digital Twin Builder™ software toolkit. The UI lets users build graphical widgets which create and chart aggregate statistics. Under the floor, a powerful in-memory data grid with an integrated compute engine transparently ensures fast, predictable performance.
Here’s an illustration of the streaming service analyzing telemetry from a large, geographically dispersed network of controllers within a power grid, with a separate real-time digital twin instance tracking each node in the grid. The streaming service simultaneously analyzes dynamic, contextual data maintained by the population of digital twin instances to immediately spot patterns of interest and maximize situational awareness:
The real-time digital twin approach creates a breakthrough for application developers that both simplifies application development and enhances introspection. Ideal for a wide range of applications, including real-time intelligent monitoring (the example above), Industrial Internet of Things (IIoT), logistics, e-commerce recommendations, financial services, and much more, the ScaleOut Digital Twin Streaming Service is currently available for preview.
