Over time, the number of legacy applications developed to support an enterprise’s operations grows significantly. Many of these applications are silo applications that recognize inputs from and deliver outputs to hard-coded interfaces only. Disconnected applications are unacceptable in today's 24×7 always-online environments. Applications that were never intended to work with each other now must cooperate closely in real-time.
Application capacity defines how many users an IT application service can support in a given response time. Another critical factor is the application’s ability to scale, which is dependent upon the application’s architecture.
The two most important scaling factors for an application are increasing the number of users that can be processed:
Scaling up usually consists of replacing existing hardware with more powerful versions, whereas scaling out usually consists of adding more processing power by spreading the load across multiple environments. Scaling up is often limited by the maximum capacity that a single monolithic environment can achieve.Learn More About Application Capacity Expansion
Shadowbase software performs whatever data transformation is required to format the database changes as read from the transaction log into usable events for the target application. Fields must be remapped from a source schema to a target schema, and can be eliminated, combined, or aggregated, while data values can be reformatted. Related data can be added from a local database. In short, any enrichment of the data required by the target application can be performed by Shadowbase technology, enabling maximum flexibility for source and target feeds.
HPE Shadowbase Streams is a heterogeneous facility that integrates critical data generated by one application and distributes it to to be acted upon immediately by other applications. Legacy applications that were never intended nor designed to work together can now interoperate with the enterprise using HPE Shadowbase software as the data distribution fabric. This powerful, efficient, and flexible architecture enables a real-time enterprise (RTE) to rapidly deliver information where and when it is needed in the format needed without customer application modification, ensuring organizational responsiveness. The application’s workload is optimized to make functional use of the delivered data.Learn More About HPE Shadowbase Streams
Today’s enterprise business insight environments require real-time change data capture updates from legacy systems integrated with online data warehouse systems. (An online data warehouse has updates streaming into it from HPE Shadowbase software to keep the warehouse’s data current.) Shadowbase real-time integration software solutions can load the business insight environment without impacting the operational systems that provide the data.Learn More About RTBI
