Much has been written about the built-in virtualization capabilities of Oracle Solaris Zones, which allow users to isolate software applications and services using flexible, software-defined boundaries in Solaris. Unlike hypervisor-based virtualization, Oracle Solaris Zones technology provides a very low-overhead, low-latency environment, which gives the appearance of multiple OS instances rather than multiple physical machines. This makes it possible to create hundreds (or even thousands) of zones on a single system, without the performance penalty which is inherent in hypervisor-based virtualization technologies.
As these Solaris Zones proliferate, it often can be necessary to restrict and monitor resource utilization of the virtual machines. A NEW white paper has now been published (Virtualization Monitoring in Solaris Zones) doing exactly that!
This technical white paper describes the opportunities for restricting resource usage of Oracle Solaris Zones, and for monitoring the different zone types from within the global zone.
The technical content of this white paper is divided into 5 separate Solaris zones environments:
1) Resource Controlling of Oracle Solaris Zones
2) Monitoring Default Zones in Oracle Solaris 11
3) Monitoring Oracle Solaris 10 Zones
4) Monitoring Oracle Solaris Kernel Zones (technical article)
5) Using OpenStack for Monitoring Oracle Solaris Zones
