No.

How is customer service and technical support?

Oracle Coherence Questions

Oracle Coherence Projects By Members

What is Oracle Coherence?

Oracle Coherence is an in-memory data grid solution that enables organizations to predictably scale mission-critical applications by providing fast access to frequently used data. As data volumes and customer expectations increase, driven by the “internet of things”, social, mobile, cloud and always-connected devices, so does the need to handle more data in real-time, offload over-burdened shared data services and provide availability guarantees.

Oracle Coherence comes with a rich set of processing and event capabilities so applications can scale processing with increased data volumes. By automatically and dynamically partitioning data, Oracle Coherence ensures continuous data availability and transactional integrity, even in the event of a server or site failure.

Oracle Coherence provides organizations with a robust scale-out data abstraction layer that brokers the supply and demand of data between applications and data sources. This cost-effectively offloads shared data services such as databases, mainframes, and partner services.
