Key Goals:

1. Transaction-centric programming paradigm

Defining a friendly programming model for large scale distributed applications that integrates the familiar notion of atomic transaction as a first-class programming language construct. This would spare programmers from the burden of implementing low level, error-prone mechanisms (e.g. distribution, persistence and fault-tolerance) attaining major reductions of the development process cost

2. Minimizing Costs

Minimizing the monitoring and administration costs by automating the provisioning of resources from the cloud based on user specified target criteria in terms of both Quality of Service and budget

3. Maximizing Scalability

Maximizing the scalability and efficiency (i.e. the costs/benefits ratio in the Cloud Computing usage-based pricing model) of the user-level services by self-tuning the middleware's internal mechanisms to ensure optimal performance in face of fluctuations of the number of allocated resources and of the workload characteristic
