NoSQL and Clouds – Introducing OGM by Hardy Ferentschik
Clouds are an interesting deployment platform, but managing state in dynamically scalable environments is not an easy task. There exist a whole range of different NoSQL solutions with strong differences in performance, capabilities, reliability, isolation and ease of use. In this talk we discuss briefly the different NoSQL solutions and show where Hibernate OGM fits into the picture. Hibernate OGM (Object Grid Mapper) is built on the robust and proven Hibernate core engine and helps you to port existing JPA (Hibernate) applications to alternative storage engines decoupling application code from a specific NoSQL solution. The project is relatively new and not all JPA features are supported; also only one storage engine is supported at the moment: Infinispan. Hardy will explain how OGM is designed, what to expect next and how to plug in your own storage engine. All this is accompanied with a demo showing how easy it is to get started.
