The LDoms (Logical Domains) are virtualization and partitioning technology that allows administrators to allocate various resources in the system such as memory, CPUs, and devices into logical groups. With this group, it then creates multiple, discrete systems, with each having their own operating system resources that are identified within a single computer system.

This technology is used by many enterprises to host multiple instances of Solaris or Linux Virtual Machines on a Sun Server. A Solaris LDoms server has different guest domains and a single control domain for monitoring and reconfiguration of guest domains. Applications are hosted in the guest domains which can be independently powered on or off without affecting other domains. This virtualization technology provides significant cost savings but it also makes the monitoring and management process much challenging.
