Coursera have interesting specializations especially in data science. A list of some useful options that are regularly offered and are quite thorough in their coverage is included below. One interesting aspect of the specializations is that they can further be included as credit options towards a degree. For example, data mining and cloud computing specializations cover the MOOC aspect of the Online MCS-DataScience degree course at UIUC. It appears that it will essentially become the trend as more degrees are offered online for working professionals.
