IEEE Transactions on Cloud Computing (http://ieeexplore.ieee.org/xpl/aboutJournal.jsp?punumber=6245519) is tough but great venue to publish your research. Generally the review time is short and you get very detailed comments from the reviewers that help you to improve the paper in future.

Does JoCCASA has any good indexing?
