Towards the typing of resource deployment

Abstract

In cloud computing, resources as files, databases, applications, and virtual machines may either scale or move from one machine to another in response to load increases and decreases (resource deployment). We study a type-based technique for analysing the deployments of resources in cloud computing. In particular, we design a type system for a concurrent object-oriented language with dynamic resource creations and movements. The type of a program is behavioural, namely it expresses the resource deployments over periods of (logical) time. Our technique admits the inference of types and may underlie the optimisation of the costs and consumption of resources.
