  • Scaffolding & templating: bootstrapping a Spring MVC app by hand can be painful. You will need directory of JAR files, bunch of bean definition files, a set of web.xml customizations, annotated POJOs, a few hibernate config files, Java Integration: Integration is seamless, web form processing classes maybe in Groovy and high performance payroll calculations in Java.Incredible wetware: Grails ecosystem is fantastic with helpful user community. Groovyblogs.org, grails.org, third party plugins. Ajax widgets, reporting, instant messaging, integration with Twitter etc.,Productivity Ethos: grails isn’t just about building web apps, but its all about executing your vision quickly. Work in two weeks can now be done in one week.

  • Development Strategies
    Spend time implementing features not configuration
    Establish developer productivity
    Support powerful practical tools
    Support Agile development
    Simpler database integration
    Strong Framework foundation

  • Choices Options Decisions
    • Architecture options
    • Web based 3 tiered
    • Technology choices
    • Open Source or NOT
    • Making the choice and living with it!
    • Cost
    • Skill Set
    • Value ( short & long term )

  • Enter Grails

  • Grails: Convention Over Configuration
    Very few config files in Grails
    Grails make most of its decisions based on sensible defaults drawn from source code.
    Add a controller called shop and action called order, Grails will expose it as a URL
    Place your view files in a directory called /views/shop/order grails will look after linking everything. Not even a single line of configuration
    Create a Domain class called Customer, Grails will automatically create a customer table in your database
    Add some fields to your Customer object, Grails will automatically create the necessary fields in your Cutsomer table on the fly with all the constraints. NO SQL required.
    The defaults are always there for you to tweak if you still like to do that.

  • Grails: Agile Philosophy
    Makes use of Dynamic language “Groovy”
    Enables easy iterations
    You can add controllers, views etc., when the app is running- without restarting it.
    The Framework makes operations easier and more maintainable at the same time.
    Code & test ( Unit, Integration tests can be run right away )

  • Grails: Rock Solid foundations
    Core is built on proven technologies
    Spring
    Hibernate
    Scheduling plugin is built on Quartz
    Search plugin is built on Lucene
    Layout engine is built on SiteMesh
    Great Support system from Vmware.

  • Grails: Scaffolding & Templating
    Building Grails app is easy as 1,2,3
    Create-app
    Run-app
    Template driven approach
    Create-controller mycontroller
    Same for views, services, domain classes etc.,
    Bootstraps for better productivity
    No Boiler plate code.
    Scaffolding
    Set of Views and controllers on the fly for Domain classes, for basic CRUD( Create Read Update Delete)

  • Grails: Java integration
    Web form processing can be in Groovy
    The performance intensive code can be in Java
    All Java libraries are available for use in Grails
    Incredible wetware

  • Enter AWS
    Why AWS
    Scalable
    Reliable & Redundant
    Secure
    Cost Effective ( Pay as you go)
    Flexible ( Any application, any platform, any language)
    Developer friendly
    Incredible array of tools to go Live!

  • AWS: EC2
    A web service that provides resizable compute capacity in the cloud.
    You get to decide the EC2 environment
    OS
    Database
    Services
    Application platform stack
    You get a Management Console and API to monitor/manage compute resources

  • AWS: S3
    Simple Web service that is used to store and retrieve large amounts of data.
    Data from anywhere, anytime, large amounts
    Inexpensive
    Amazon runs on S3

  • AWS: RDS
    Web service that provides access to MySQL/ Oracle databases on the cloud.
    Manages backup, scaling, updates etc.,
    Provides all database capabilities.

  • Demo:
    Domain Driven design
    Use tests ( Unit & integration )
    Demonstration of a simple grail app
    Deployment to AWS

  • Summary
    Web Applications today are complex and need Rapid responses from Engineering teams
    Define strategies and match them to Requirements
    We looked at some of the tools and services that match these demanding requirement
    Grails, Groovy and AWS.
    How this becomes a potent combination.
    Eliminates unnecessary config time and complexity.
