The computing resource level architecture allows end-users to directly control its underlying computer resources, such as VM (virtual machine) operations, scaling, networking, etc. However, setting up and maintaining a working environment is complex and time consuming for end-users and resource management is also a heavy-weight task for the providers. In contrast, the application resource level architecture automatically controls its underlying computer resources so that end-users can concentrate on their core business. In this paper, we propose a new architecture called Elastic Application Container (EAC) that enables the end-users to efficiently develop and deliver light-weight, elastic, multi-tenant, and portable applications. The EAC is an abstract representation which hides all its abstractions of the underlying VMs. We believe that our EAC architecture has the potential to become the foundation of future application resource level model in this research area.
