System provisioning, resource allocation, and system configuration decisions for work flow I/O-intensive applications are complex even for expert users. One factor making the problem space more complex is that users face decisions at multiple levels: allocating resources to individual sub-systems (e.g., the application layer, the storage layer) and configuring each of these optimally (e.g., replication level, chunk size, caching policies in case of storage) which have a large impact on overall application performance. This paper presents their progress on addressing the problem of supporting these provisioning, allocation and configuration decisions for work-flow applications.
