Join Date: Feb Join Date: Jul Solaris Zones , you have a single copy of the OS that is shared between the various instances. You can have some isolation on patches, with "full zone" deployments. But in the end all the zones share the same copy of the kernel. If you have a hardware issue, you would have to take outage on all zones.
So in summary zones are software isolation, they look isolated because the OS provides that view. Containers are the opposite, they can be compared in some respects to vmware. They have a control domain and run off the hypervisor. You can failover containers from one to another, online failover..
They are better suited to production kind environment. They are getting better and better, because oracle now wants a share of the virtualization pie and wants to compete with Vmware and Microsoft. Join Date: Jun These 2 Users Gave Thanks to h foorsa.
Join Date: Mar 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. Best practice is to set up a Host called a Global Zone. 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. Our Team. Full-Stack JS Certificate. RisingStack in the JS Community.

The need for containers Hypervisor based virtualization technologies have existed for a long time now. What are containers? Type of containers that can be installed on the host should work with the kernel of the host. Hence, you cannot install a Windows container on a Linux host or vice-versa. Isolation and security — the isolation between the host and the container is not as strong as hypervisor-based virtualization since all containers share the same kernel of the host and there have been cases in the past where a process in the container has managed to escape into the kernel space of the host.
Common cases where containers can be used As of now, I have noticed that containers are being used for two major uses — as a usual operating system or as an application packaging mechanism. OS containers OS containers are virtual environments that share the kernel of the host operating system but provide user space isolation. Application containers While OS containers are designed to run multiple processes and services, application containers are designed to package and run a single service.
So even though they share the same kernel of the host there are subtle differences make them different, which I would like to talk about using the example of a Docker container: Run a single service as a container When a Docker container is launched, it runs a single process. Layers of containers Any RUN commands you specify in the Dockerfile creates a new layer for the container. Directories in Global Zone can be mounted to a Zone's dedicated directory. You can also choose the access mode to the mounted directories, enabling either read-only or read-write.
Each Zone has a virtual network interface for communication with other systems on the network. Zones in the same server can also communicate through the network.
Global Zones and Zones have their own specific host names and IP addresses. What is the difference between detached and disassociate state of plexes? What is the boot process of VxVM?
