Hi man I'm a Solaris Admin so this is my experience.
In Solaris Zones and Containers are almost the same thing. In Solaris 8 and 9 Zones where called containers. In Solaris 10 and later the term zone was used instead. Zones are a form of visualization & isolation. Best practice is to set up a Host called a Global Zone. The global zone then hosts one or more "Full Root", "Sparse Root" or "Branded" zones.
-Full root is a full Solaris install without any shared files.
-A sparse zone has 4 directory's that it shares with the global zone.
-Banded zones are zone that may not share anything with the global. A branded zone might be a Solaris 9 hosted on Solaris 10, or it can also be a Linux distro hosted on the global zone.
I hope this helps

NAME
zcons - Zone console device driver
DESCRIPTION
The zcons character driver exports the console for system zones. The driver is comprised of two "sides:" a master side with which applica-
tions in the global zone communicate, and a slave side, which receives I/O from the master side. The slave side is available in the global
zones.
Applications must not depend on the location of /dev or /devices entries exported by zcons. Inside a zone, the zcons slave side is fronted
by /dev/console and other console-related symbolic links, which are used by applications that expect to write to the system console.
The zcons driver is Sun Private, and may change in future releases.
FILES
/dev/zcons/<zonename>/masterconsole
Global zone master side console for zone <zonename>.
/dev/zcons/<zonename>/slaveconsole
Global zone slave side console for zone <zonename>.
/dev/zconsole
Non-global zone console (slave side).
