About Crowd Data Center

Crowd Data Center is a cluster of Crowd nodes designed to provide:

  • High availability and failover – If one cluster node goes down, then the remaining cluster nodes can continue servicing requests so that users have uninterrupted access to Crowd, and other systems connected to it.
  • Instant scalability – You can rapidly provision extra capacity with no downtime.


Crowd Data Center consists of a cluster of dedicated machines, connected like this:


ロード バランサは、クラスタ ノードに対するユーザーからのリクエストを分散します。あるクラスタ ノードがダウンした場合、ロード バランサはすぐに故障を検出し、数秒以内に他のノードにリクエストを自動的に振り向けます。セッション アフィニティをサポートする任意のロード バランサを使用できます。

アプリケーション ノード

Data Center ノードのクラスタは、着信するリクエストの負荷を共有します。1 つのクラスタノードで障害が起きても、リクエストはすぐに他のノードに振り向けられるため、ユーザーが可用性を失うことは事実上ありません。


Data Center supports the same databases that are supported for Crowd Server. It also supports any shared file system, which stores: import/export files, plugins, shared caches, and any data directory which includes attachments, avatars and icons.
