Dig deeper into Grails architecture and discover how this application framework works its magic. Written by a core developer on the Grails team, this practical guide takes you behind the curtain to reveal the inner workings of its 2.0 feature set. You'll learn best practices for building and deploying Grails applications, including performance, security, scaling, tuning, debugging, and monitoring.

Understand how Grails integrates with Groovy, Spring, Hibernate, and other JVM technologies, and learn how to create and use plugins to augment your application's functionality. Once you know how Grails adds behavior by convention, you can solve problems more easily and develop applications more intuitively.Write simpler, more powerful code with the Groovy languageManage persistence in Grails, using Hibernate or a NoSQL datastoreLearn how Grails uses Spring's functionality and optional modulesDiscover how Hibernate handles details for storing and retrieving dataIntegrate technologies for messaging, mail, creating web services, and other JEE technologiesBypass convention and configure Grails manuallyLearn a general approach to upgrading applications and pluginsUse Grails to develop and deploy IaaS and PaaS applications
