You just deployed your highly-modularized Spring web application to your “Cloud in a Box” made up of multiple bare-metal or virtualized nodes. You front-end your web app with a HTTP load-balancer to spread out the requests. But wait a second, the view layer is just a proxy to the service layer which forms the meat of your application. So does adding a HTTP load-balancer suffice? Grid computing software could help here to scale out the service layer but it's not without limitations.
In this session, we will look at these limitations and explore how some freely downloadable PaaS cloud tools such as Appistry CloudIQ Community Edition, makes scaling out the service components easy. We will walk through a demo of deploying a Spring web application to our enterprise “Cloud in a Box”, load test it and watch it scale.
