How do Solaris Containers compare to the virtual machine approach advocated by VMware?
Jeff Victor: Containers provide multiple isolated workload environments with strict security and resource management features. Because there is only one operating system image, the Solaris Containers method is very efficient and reduces management chores. VMware provides the ability to simultaneously host multiple operating system images, as well as the ability to choose different operating system types (Linux, Solaris, and Windows). However, as with all virtual machines, there is a performance penalty with VMware. Also, with VMware and other virtual machine technologies each operating system image must be managed separately.
