A recent announcement that NZ is about to become the land of the long white local cloud is interesting; the NZ government obviously sees a need to know where its data is, and furthermore that it is within the borders that it controls.
We are seeing recognition that just flinging your data out there somewhere and trusting that its security is intact is inappropriate in many circumstances. Babcock, in his book "Management Strategies For The Cloud Revolution" (McGraw Hill, 2011), points out that the Cloud Security Alliance "urges in unvarnished terms that users should not assume that cloud computing operates with all the layers of protection that a business normally enjoys”
Rigorous contracts can mitigate many concerns. However we see here another approach, where cloud computing is being refined into variants on the theme, in much the same way that networks themselves have become defined as intranet / extranet / internet, depending upon their level of openness / security.
