Solaris Zones
Due Credit:
So as a system what more will I speak about than my funny old operating system? So let me give you some insight into what the great Solaris is all about. Here I have added some useful
information about Solaris zones, one of the most attractive features of Solaris.
A Solaris zone provides a virtual operating system environment within a single physical instance.
Applications can run in an isolated and secure environment.
Isolation prevents an application running in one zone from monitoring or affecting an application running in a different zone.
If any application fails means that wonÂt affect the other application.
Example:
Suppose the email server and web server applications need to run in isolated environments that make it appear as if they are running on physically separate machine, then you can have separate zones.
2 Types of zones
1.Global zone
2.Non - global zone
Global zone:
Global zone as the server itself.
Where you can login as root and have full control of the entire system.
It has access to the physical hardware and can control all process.
It has the authority to create and control new zones.
It can look inside the non global zone to see how they are configured, monitor, and control them.
Non-global zone:
A non global zone is created from the global zone and also managed by it.
You can have up to 8192 non global zones.
Applications that run in a non global zone are isolated from applications running in a separate non global zone.
Create the zone on the resource pool
Creating a zone requires the following steps:
Configuration - defines zone properties, such as required file system and network interfaces.
Installation - create the zone on the system.
Virtual platform management - use zone tools to boot, halt, or reboot the zone.
Zone login - move in and out of the zone to perform administrative tasks.
