In order to run applications on a Cloud, one needs a flexible middleware that eases the development and the deployment process. Middleware Approach to Deploy Application on Cloud GridGain provides a middleware that aims to develop and run applications on both public and private Clouds without any changes in the application code.  It is also possible to write dedicated applications based on the map/reduce programming model. Although GridGain provides a mechanism to seamlessly deploy applications on a grid or a Cloud, it does not support the deployment of the infrastructure itself. It does, however, provide protocols to discover running GridGain nodes and organize them into topologies (Local Grid, Global Grid, etc.) to run applications on only a subset of all nodes. Elastic Grid infrastructure provides dynamic allocation, deployment, and management of Java applications through the Cloud.  It also offers a Cloud virtualization layer that abstracts specific Cloud computin...
