A JEE application is easier to write even with complex requirements since the business logic is organized in reusable components and the server provides the underlying services — in the form of a container — for each component type. We thought it would be a novel idea to add even more power to the concept of container services in JEE by adding support for some of the powerful ideas of cloud computing — namely parallelism, elasticity, multi-tenancy, and security. This article describes the strategies and patterns to extend JEE containers and applications with cloud computing characteristics. It includes: An outline of each cloud characteristic we integrated. A layout of the existing characteristics of JEE applications. A description of our approach to extend the JEE container to the cloud. A design strategy for this type of migration, one that includes the concepts of parallelism, synchronization, storage, elasticity, multi-tenancy, and security. Cloud characteristics Figure 1 explains what cloud is and the different cloud deployment models. Figu
