Building a Grails Application

Inside Staged Applications

• Stager packages applications into executable droplets– provides a runtime container– can rewrite configuration files– can add libraries

14

Inside Staged Applications (continued)

• For Spring/Grails applications– provides a servlet container– deploys the app into the container– configures the container to listen on the correct port– adds auto-reconfiguration lib to the class path– rewrites web.xml

• registers auto-reconfiguration BeanFactoryPostProcessor• registers CloudApplicationContextInitializer

– adds JDBC drivers to class path• MySQL or PostgreSQL depending on bound services

Inspecting a staged application

“Hey you! Leave my app alone!”

• No Problem• Plain Java framework

– bare minimum staging– no manipulation of configuration files– no additions to the class path– just your application

Growing with Demand

• Scale up in seconds– vmc instances myapp +2

• Scale down in seconds– vmc instances myapp -2

• Monitor your application instances– per instance: memory, CPU, disk, uptime– vmc stats myapp

Surviving Disaster

• Applications crash– impossible to avoid– it will happen, sooner or later

• Optimize for mean time to recovery– mean time between failures is not as important
