In computing, Hazelcast® is an open source in-memory data grid based on Java. It is also the name of the company developing the product. The Hazelcast company is funded by venture capital. In a Hazelcast grid, data is evenly distributed among the nodes of a computer cluster, allowing for horizontal scaling both in terms of available storage space and processing power. Backups are also distributed in a similar fashion to other nodes, based on configuration, thereby protecting against single node failure. ==Usage== Typical use-cases for Hazelcast include: * Distributed cache, often in front of a database * storage for temporal data, like web sessions * in-memory data processing and analytics * memcached alternative with a protocol compatible interface〔(【引用サイトリンク】title=Memcache Client )〕 * Cross-JVM communication and shared storage Hazelcast is often used as an underlying library or system onto which other higher level features are built, with examples including: * Vert.x utilizes it for shared storage * Underlying MapReduce framework/executor 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hazelcast」の詳細全文を読む スポンサード リンク
