Dig deeper into Grails architecture anddiscover how this application framework works its magic. Written by a coredeveloper on the Grails team, this practical guide takes you behind the curtainto reveal the inner workings of its 2.0 feature set. You’ll learn bestpractices for building and deploying Grails applications, includingperformance, security, scaling, tuning, debugging, and monitoring.


Understand how Grails integrates with Groovy, Spring, Hibernate, and other JVMtechnologies, and learn how to create and use plugins to augment yourapplication’s functionality. Once you know how Grails adds behavior byconvention, you can solve problems more easily and develop applications moreintuitively.
