Virtual machines are an abstraction of the hardware layer. Whereas in Virtualization, hypervisors provide an entire virtual machine to the guest(including Kernal). Each container is a different application. Containers are an abstraction of the application layer. Any changes made inside the container is never reflected on the host or even other containers running on the same host. The entire user space is explicitly dedicated to the application. Difference between virtualization and containerizationĬontainers provide an isolated environment for running the application. Most famous containerization environments are Docker and Kubernetes. Now when you wish to run the application on another system, the container is deployed which will give a bug-free environment as all the dependencies and libraries are wrapped together. So basically, an application that is being developed and deployed is bundled and wrapped together with all its configuration files and dependencies. This problem was solved by the containerization concept.
DOCKER AND KUBERNETES INTERVIEW QUESTIONS AND ANSWERS SOFTWARE
Usually, in the software development process, code developed on one machine might not work perfectly fine on any other machine because of the dependencies. The virtual environment created by the hypervisor is called Virtual Machine. A software called Hypervisor makes this kind of splitting possible. Virtualization lets you split one system into many different sections which act like separate, distinct individual systems.
These virtual versions or environments are created from a single physical hardware system. Virtualization is the process of creating a software-based, virtual version of something(compute storage, servers, application, etc.). Type 2: This kind of hypervisor makes use of the underlying host operating system.It has direct access to your host’s system hardware and hence does not require a base server operating system. It runs directly on the underlying host system. Type 1: It’s also called Native Hypervisor or Bare metal Hypervisor.You can basically have multiple OS on a single host system. It divides the host system and allocates the resources to each divided virtual environment. It is also called Virtual Machine Monitor.
A hypervisor is a software that makes virtualization possible.
