With the rate of cloud spending predicted to outpace overall IT spending six to one over the next few years, organizations are rightly concerned about ensuring that applications in the cloud enjoy the same level of security as apps deployed in data centers. Using the public cloud does alter your attack surface area-and leveraging multiple public and private clouds (aka multi-cloud) does so even more. Some threats get bigger, some get smaller. Some even go away, or at least drift out of your control, while new threats should move front and center in your security thinking.
