ScaleOut StreamServer®

ScaleOut StreamServer®

Perform Stateful Stream Processing for Deep Introspection

ScaleOut StreamServer® combines a scalable, stream-processing compute engine with an integrated, in-memory data grid into a powerful, unified software platform for stateful stream-processing. Now you can perform lightning-fast event analysis using sophisticated in-memory state tracking with “digital twin” models to provide deep introspection and precise real-time feedback.

The ScaleOut Digital Twin Builder™ software toolkit dramatically simplifies the development of Java and C#-based digital twin models and their deployment on ScaleOut StreamServer. Digital twin models enable stream-processing applications to track dynamic state information for each data source and analyze its incoming events with a richer context than previously possible. This leads to deeper real-time introspection and better feedback and alerting.

ScaleOut StreamServer incorporates all of the features of ScaleOut ComputeServer, enabling applications to perform data-parallel analyses on live, fast-changing data. This gives applications the ability to immediately detect aggregate trends and generate feedback or alerts. Combined with digital twin models, data-parallel analytics performed in real time offer new insights on the dynamic behavior of data sources that previously were only available with offline, batch processing.

ScaleOut StreamServer®

Wide Range of Applications

Stateful stream-processing with digital twins offers deeper introspection than previously possible across a wide range of applications, including financial services, e-commerce, Internet of Things (IoT), medical systems, manufacturing, logistics, and much more.

Here’s just one example: A medical monitoring system can use a dynamic, digital twin model of a patient combined with machine-learning techniques to take into account a patient’s detailed history, medications, and current status when evaluating incoming device telemetry. This allows the system to generate more intelligent and timely alerts to medical professionals.

Breakthrough Architecture

Unlike mainstream platforms such as Apache Flink, Spark, and Storm, ScaleOut StreamServer automatically dispatches incoming streaming events to in-memory, object-oriented, digital twin models of data sources for analysis. Other platforms need to pull state information from remote data stores, such as database servers and distributed caches; this creates delays and network bottlenecks. ScaleOut StreamServer processes incoming data streams within digital twins stored in an in-memory data grid — where the data lives — ensuring minimum access latency and peak stream-processing throughput.

ScaleOut ComputeServer®

ScaleOut ComputeServer®

Analyze Your Live Data for Operational Intelligence

ScaleOut ComputeServer combines distributed, in-memory storage with a scalable compute engine to enable blazingly fast, data-parallel computation on live, fast-changing data. This gives you “operational intelligence” – the ability to analyze data in real time and provide immediate insights and feedback within live, operational systems. Now you can capture perishable business opportunities in your live data as they happen.

Fast Results for Live Data, Scalable Performance, Intuitive APIs

ScaleOut ComputeServer®

In-Memory, Data-Parallel Computing

ScaleOut ComputeServer brings the power of data-parallel computing to distributed, in-memory data. Its compute engine minimizes data motion and delivers blazingly fast execution times. ComputeServer uses techniques from parallel supercomputing, such as multicast and global combining, to deliver results as fast as possible. These capabilities are integrated into an intuitive, easy to use SDK with automatic code shipping that makes application development in Java, C#, and C/C++ simple and straightforward.

Unique Capabilities for Operational Intelligence

Unlike in-memory computing platforms that focus on analyzing streams of data, ScaleOut ComputeServer was specifically designed for operational intelligence within live systems. Its object-oriented, in-memory data storage lets you create a scalable, highly available model of real-world entities (such as portfolios, e-commerce shoppers, or the Internet of Things) which easily can be updated as changes occur. Data-parallel computing enables fast analysis to detect emerging patterns and generate immediate feedback. You have a mission-critical system, and now you have the operational intelligence you need for peak performance.

ScaleOut StateServer®

Integrated Scalability and High Availability

Scalability is in our DNA. Every aspect of our in-memory data grid’s architecture is designed to deliver linearly scalable performance with integrated high availability. This means that you can add servers to meet the demands of your business and always expect fast response times in accessing your data. If and when server failures occur, our patented technology ensures that your data will be there and your data grid will recover fast and reliably.

Ease of Use to Keep Your TCO Low

Whether it’s deploying and managing a ScaleOut cluster or developing a new application, we make ease of use a top priority for our products. Our goal is to take care of the grid’s inner workings and keep the APIs as simple as possible so that you can focus on your application’s structure and performance. ScaleOut StateServer automates cluster membership, data partitioning, and load-balancing, and it self-heals with automatic rebalancing after a server failure.
