First International Workshop on
Workflow Models, Systems, Services and Applications in the Cloud (CloudFlow) 2012

To be held in conjunction with the
26th IEEE International Parallel & Distributed Processing Symposium (IPDPS) 2012
Shanghai, China
May 21-25, 2012.

Overview
Cloud computing is gaining tremendous momentum in both academia and industry,
more and more people are migrating their data and applications into the Cloud.
We have observed wide adoption of the MapReduce computing model and the open
source Hadoop system for large scale distributed data processing, and a
variety of ad hoc mashup techniques that weave together Web applications.
However, these are just first steps towards managing complex task and data
dependencies in the Cloud, as there are more challenging issues such as large
parameter space exploration, data partitioning and distribution, scheduling
and optimization, smart reruns, and provenance tracking associated with
workflow execution.

Cloud needs structured and mature workflow technologies to handle such issues,
and vice versa, as Cloud offers unprecedented scalability to workflow systems,
and could potentially change the way we perceive and conduct research and
experiments. The scale and complexity of the science and data analytics
problems that can be handled can be greatly increased on the Cloud, and the
on-demand nature of resource allocation on the Cloud will also help improve
resource utilization and user experience.

As Cloud computing provides a paradigm-shifting utility-oriented computing
model in terms of the unprecedented size of datacenter-level resource pool
and the on-demand resource provisioning mechanism, there are lots of
challenges in bringing Cloud and workflows together. We need high level
languages and computing models for large scale workflow specification; we need
to adapt existing workflow architectures into the Cloud, and integrate
workflow systems with Cloud infrastructure and resources; we also need to
leverage Cloud data storage technologies to efficiently distribute data over
a large number of nodes and explore data locality during computation etc. We
organize the CloudFlow workshop as a venue for the workflow and Cloud
communities to define models and paradigms, present their state-of-the-art
work, share their thoughts and experiences, and explore new directions in
realizing workflows in the Cloud.
