Re: Zones and Containers


Short anwser - zones is the technology for making a virtual OS 
environment.  Containers is the marketing term when you combine zones 
with resource controls.

For all intents and purposes the same thing.

Re: Zones and Containers

Greg,

Adrian is correct to better sum up comparison to VMWare.

VMware uses hosts OS which is the same thing as Zone or Global Zones in 
Solaris
VMware uses guess OS which  is the same thing as Containers or 
NON-Global Zones.

So the Gobal Zones will control the containers just as Hosts OS controls 
the guess OS.

This should clarify the answer further.

I think you are confusing Logical Domains (LDOMS) with containers.
LDOMs have a separate kernel for each OS instance, zones/containers do
not, sparse or global.  VMWare has a kernel for each OS instance.

There is no real guest OS with containers or zones, rather there is a
virtualised OS environment which simulates a real OS.  Each VMWare
guest is a real OS, consuming kernel memory and cpu overhead.

Tony,

Your confused. LDOM uses what is known as hypervisor type technology. 
Global Zones
doesn't use that.

Tony,

First off off in reference to Global Zones - You have 2 root's you can 
implement.
They are:

Phillip, I think the confusion comes for the terminology (like most 
arguments, the cause is the lack of a common metaphor!)

A  Solaris installation has one zone, the Global Zone.  These is only 
one Global Zone.

Whole Root and Sparse Root are the two types of user created Non-global zone.
