The solaris10 brand allows you to run Solaris 10 software on OpenSolaris.
The lx brand allows you to run some Linux software on a Solaris 10 system.
The flexible and dynamic resource controls can automatically adapt to the
changing needs of one or more workloads.
A configurable security boundary provides the ability to relax or strengthen
the privileges of each Container individually.
Containers are a tightly integrated feature of Oracle Solaris, and can benefit
from innovations in Solaris such as ZFS and DTrace.
6.6 Summary
Containers are a very popular and feature-rich form of system virtualization that
are used in production environments in data centers all over the world. In prac-
tice, the more common uses of Containers include the following situations:
Consolidating applications from multiple servers to fewer servers, especially
as a no-cost virtual server.
Hardening an OS environment with read-only mounts and minimal privi-
leges, especially for Internet-facing environments.
Migrating and consolidating workloads from earlier versions of Solaris to
Oracle Solaris 10, using Solaris 8 Containers and Solaris 9 Containers.
Hosting environments such as cloud computing, ISPs, and web hosting,
where a homogeneous environment is preferred by the hosting organization,
and where quick provisioning is important. Each customer can be configured
on multiple systems, ready to boot on the most lightly loaded system.
Software development environments, which also benefit from rapid provision-
ing and homogeneity, giving each developer full privileges in that Container.
Rapid provisioning for short-lived environments—for example, functionality
testing. A cloned Container provides a well-defined starting point.
High-scale virtualization, in which dozens or hundreds of VEs reside in one
computer, because of the superior efficiency of Containers.
Released as a feature set of Solaris 10 in early 2005, Containers have achieved
broad support from independent software vendors (ISVs). Network virtualization
adds a new dimension to their usefulness for OpenSolaris and the future.
