Tech Article: Securing a Cloud-Based Data Center
When you build a private cloud, you need to protect sensitive data not only while it's in storage, but also during transmission between servers and clients, and when it's being used by an application. When a project is completed, the cloud must securely delete sensitive data and make sure the original data is kept secure. These are just some of the many security precautions a sysadmin needs to take to secure data in a cloud infrastructure. Orgad, Ron, and Richard and explain the rest and show you how to employ the security features in Oracle Solaris 11 to protect your cloud infrastructure. Part 2 of a three-part article on cloud deployments that use the Oracle Solaris Remote Lab as a case study.

Tech Article: Delegating a ZFS Dataset to a Non-Global Zone
Adding a dataset to a non-global zone does not give the non-global zone's administrator control over the dataset's properties. They are retained by the global zone's administrator. Delegating a dataset, however, does give the non-global zone's administrator control over the dataset's properties. Alexandre explains how.
