  Workflow is a common term used to describe a systematic breakdown of tasks
that need to be performed to solve a problem. This concept has found best use
in scientific and business applications for streamlining and improving the
performance of the underlying processes targeted towards achieving an outcome.
The growing complexity of big data analytical problems has invited the use of
scientific workflows for performing complex tasks for specific domain
applications. This research investigates the efficacy of workflow-based big
data analytics in the cloud environment, giving insights on the research
already performed in the area and possible future research directions in the
field.
