One of the key breakthrough technologies in Solaris 10, Solaris Container has the ability to promote server consolidation, as well as improve application availability and manageability. In this interview, Inner Circle plays 20-plus questions with Sun virtualization experts Joost Pronk van Hoogeveen, Jeff Victor, and Chien-Hua Yen to more fully understand the potential, capabilities, and limitations of Solaris Containers and Solaris Zones.
IC: What are the differences among Logical Domains, Solaris Zones, and Solaris Containers?
Joost Pronk van Hoogeveen: Domains are a type of hardware partitioning, so the partitioning is done at the hardware level. Solaris Zones are part of Solaris Containers technology. As such, Zones manage the namespace isolation (separate IP addresses and users, for example) for Containers. Containers and Zones are a type of operating system virtualization, where the partitioning is not done at the hardware level, but rather within the operating system itself.
IC: Are Zones and Containers the same thing?
