I think increased concerns about data security in the cloud was probably the most important development. Sure, there were always concerns, but there were a lot of high profile (and expensive) data breaches in 2014. Ultimately this will probably be a good thing. As there are more and more high value assets in the cloud (IP, customer data, financial information, medical info, etc.) the will be an increased interest by sophisticated and motivated criminals. Companies need to recognize this, fix their shoddy security practices, and improve data security in the cloud.
