Apache Jackrabbit Oak - Scale your content repository to the cloud
9 likes7,972 views
The document discusses Apache Jackrabbit Oak, an open source content repository that can scale to the cloud. It provides an overview of content, repositories, scaling techniques using different storage backends like TarMK and MongoMK, and how Oak can be deployed in the cloud using technologies like S3 and MongoDB. The presentation covers key JCR concepts and shows how Oak can be used for applications like content management, digital asset management, and invoice management.
