Microsoft in Jan 2010 pushed for more legislation of cloud computing. Because of the nature of the cloud, it has legal problems. Firstly, the 1986 Electronic Communications Privacy Act is woefully outdated and needs serious revisions. Also, jurisdiction of cloud correspondence is a quagmire. If someone in NJ sends an email to someone in FL, but the cloud server is in NY, who has jurisdiction? It is even more tangled if the cloud server is located internationally, since there is no standardization.
Since different nations have various concepts of privacy, companies, like the medical providers are very reluctant to go to the cloud, for fear of violating patient confidential records. Different jurisdictions in the US have different laws about sharing personal information. Shared standards would be important for this.
The Cloud Computing Act, still be drafted, could address many of these issues, at least in the United States. Getting international legislation that is standardized is another question.
It is more than obvious that updates in electronic communications laws are critical. Cloud storage is estimated to be a many billion dollar industry, lets get the laws in place to regulate this.
