It has been built into linux in the form of lxc for over 10 years and similar operating system level virtualization has also been offered by freebsd jails.
What is container technology.
This set of extensions not only adds features to docker but also makes it possible for docker the company to add commercial support.
Container standards and industry leadership.
A lot of enterprises today have been facing challenges in running applications successfully across varied computing environments.
Containerization has taken a secure by default approach believing that security should be inherent in the platform and not a separately deployed and configured solution.
Provide easier deployment of repetitive jobs and tasks.
But container technology is not new.
Docker developed a linux container technology one that is portable flexible and easy to deploy.
Container technology has roots in partitioning and chroot process isolation developed as part of linux.
Container technology providers such as docker continue to actively address container security challenges.
Containers are being deployed to support one or more similar processes which often run in the background such as etl functions or batch jobs.
Container technology is a solution to run a software application reliably when deployed in a different environment other than the one in which it was created.
This decoupling allows container based applications to be deployed easily and consistently regardless of whether the target environment is a private data center the public cloud or even a developer s personal laptop.
The modern forms of containers are expressed in application containerization such as docker and in system containerization such as linux containers.
Container technology supports streamlined build test and deployment from the same container images.
Container technology also simply known as just a container is a method to package an application so it can be run with its dependencies isolated from other processes.
When a software application is ported from one environment to another say from staging to production there is a possibility of issues.
