Migrating the SimTech workflow management system to a cloud infrastructure

Abstract

The SimTech Simulation Workflow Management System has been developed to allow scientist to easily create, manage, and execute simulation workflows. It is currently executed on local computers or in traditional data centers, but it could benefit from the scalability and utility computing model that cloud computing offers. This thesis investigates the feasibility of migrating the SimTech Simulation Workflow Management System to the cloud. Cloud service models and service providers are inspected and a prototypical migration into Amazon's cloud environment is realized. The result is that all but two component can be migrated into the cloud with no or very small changes necessary. Of these components, all but two are also widely offered as PaaS solutions. In conclusion, a significant part of the system could be migrated to a cloud infrastructure right now, but some work is necessary to utilize the full potential of the cloud. For a full migration, one component has to be heavily modified or redeveloped.
