| <h2>About the Project</h2> |
| <p>Apache Geode is a data management platform that provides real-time, consistent access to data-intensive applications throughout widely distributed cloud architectures.</p> |
| |
| <p>Geode pools memory, CPU, network resources, and optionally local disk across multiple processes |
| to manage application objects and behavior. It uses dynamic replication and data partitioning |
| techniques to implement high availability, improved performance, scalability, and fault |
| tolerance. In addition to being a distributed data container, Apache Geode is an in-memory data |
| management system that provides reliable asynchronous event notifications and guaranteed message |
| delivery.</p> |
| |
| <p>Apache Geode is a mature, robust technology originally developed by GemStone Systems. |
| Commercially available as GemFireâ„¢, it was first deployed in the financial sector as the transactional, low-latency data engine used |
| in Wall Street trading platforms. |
| Today Apache Geode technology is used by hundreds of enterprise customers for high-scale business applications that must meet low latency and 24x7 availability requirements.</p> |
