Containerization serves in the form of a lightweight
option to machine virtualization which involves summarizing an application in
any container with its very own operating surroundings. The procedure offers
the advantages of loading a particular application on a machine since the
application can easily be run on any specific machine without any kind of
worries regarding dependencies. Recently, containerization has gained huge
popularity.
Brief
Explanation of the Term
Containerization or container-based virtualization
is also called application containerization. It is basically an OS-level
virtualization procedure for using and operating distributed applications
without the launch of virtual machines for different applications. Perhaps, a
number of isolated systems known as containers are used on single control hosts
accessing single kernels. Since different containers share similar OS kernels
as host, containers can serve to be more efficient in comparison to virtual
machines that need separate OS instances.
Different containers used in this procedure hold all the necessary
components required for running a desired software like environment variables,
libraries and files. Host OS constrains the access of the container to certain
physical resources like memory and Central Processing Unit. This way a single
container is not able to consume all the physical resources of the host.
The Benefits of
Containerization
Containerization gained huge popularity with Docker-
an open source that developed the procedure of giving containers improved
portability. This allowed the containers to move about in almost any system
that deals in sharing host OS type without the need of code changes.
Containerization helps in the gain of efficiency for storage, memory and CPU in
comparison to traditional virtualization. Containers do not require overheads
as needed by virtual machines and therefore it is always possible to support
more containers using similar infrastructure. This way containerization helps
in improving performance since there is one single OS that takes care of the
hardware calls.
