This could be when a developer pushes code from the dev environment to a test environment, and then further on. For example: A developer wrote the application code in Windows, but the upper environment s test, stage, or prod are Linux-based. In such a case, there is the chance that some functionality will stop working when the OS changes.
So, basically, when the supporting software environment is not identical, then the chances of intermittent failure are higher. Or you'll rely on the behavior of a certain version of an SSL library and another one will be installed. You'll run your tests on Debian and production is on RedHat and all sorts of weird things happen. The change may not be just of the computing environment, but can also be of the network.
Hykes also added that "the network topology might be different, or the security policies and storage might be different, but the software has to run on it. Agile environment : The biggest advantage in favor of container technologies is that they can be created much faster than VM instances.
Their lightweight footprint enables less overhead in terms of performance and size. Enhanced productivity : Containers increase developer productivity by removing cross-service dependencies and conflicts. Each container can be seen as a different microservice and thus can be independently upgraded without any concerns regarding their sync.
Version control : Each image of a container can be version controlled, thus enabling tracking of different versions of the container, watch out for differences between versions, etc. Computing environment portability : Containers encapsulate all the relevant details like application dependencies and operating systems, which are essential to run the application.
This helps ease the portability of the container image from one environment to another. Standardization : Most containers are based on open standards and can run on all major Linux distributions, Microsoft, etc. Featured reads.

Another implementation, called simply 'LXC', is not compatible with libvirt, but is more flexible with more userspace tools.
It is possible to switch between the two, though there are peculiarities which can cause confusion. Docker can offer the following capabilities: Portable deployment across machines: you can use Docker to create a single object containing all your bundled applications. This object can then be transferred and quickly installed onto any other Docker-enabled Linux host. Versioning: Docker includes git-like capabilities for tracking successive versions of a container, inspecting the diff between versions, committing new versions, rolling back etc.
Component reuse: Docker allows building or stacking of already created packages. Again, think of the AWS common pool of different configs and distros — this is very similar. Tooling and CLI LXC tooling sticks close to what system administrators running bare metal servers are used to, with direct SSH access allowing the use of automation scripts your team might have used on bare metal or VMs running on VirtualBox and other virtualized production environments.
Docker Machine - A tool for creating Docker-enabled virtual machines. Ease Of Use Docker and LXC both provide ample documentation, with helpful guides for creating and deploying containers. Related Container Technology As alluded to above, the world of containers is particularly dynamic, and involves a lot of innovation both around LXC, Docker, as well as alternative containerization technologies. Apache Mesos - An open source kernel for distributed systems, Apache Mesos can run different kinds of distributed jobs, including containers.
Conclusion LXC offers the advantages of a VE on Linux, mainly the ability to isolate your own private workloads from one another. Containers on the other hand are not real things. Linux namespaces and cgroups ARE first class objects. NOT containers. I am trying to make this distinction very clear to make a point. The designs are different. Since containers are made with specific building blocks of namespaces this allows for doing some super neat things like sharing namespaces.
This specific example can be seen in a demo by Arnaud Porterie from our talk at Dockercon EU in You can have your application running in one container, then in a different container sharing a net namespace you can run wireshark and inspect the packets from the first container.
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. I hope this helps. Find all posts by DukeNuke2. This might be useful Below is pdf from Sun on how to set up zones and with containers.
