What are zones strengths compared to other server virtualization solutions?
• Cost: zones are a feature of the operating system. There is no extra charge for using them. • Integration: Zones are integrated into the operating system, providing seamless functionality and a smooth upgrade path. • Portability: Zones are not tied to any one hardware platform. As a device-independent feature set of OpenSolaris, their functionality is exactly the same on all hardware to which OpenSolaris has been ported. • Observability: The Global Zone has visibility into all activity in all zones, including viewing process and network activity, system-wide accounting and auditing, etc. This makes it possible to find performance problems and resolve inter-zone conflicts, both of which are extremely difficult problems on most other SV solutions. It is even possible to re-host applications typically found on different systems (e.g. web server and app server) on different zones in the same system, and then use DTrace to analyze their interactions. • Manageability: You can manage all of
