A hypervisor is a software that makes virtualization happen because of which is sometimes referred to as the Virtual Machine Monitor. This divides the resources of the host system and allocates them to each guest environment installed.
This means that multiple OS can be installed on a single host system. Hypervisors are of 2 types:
1. Native Hypervisor: This type is also called a Bare-metal Hypervisor and runs directly on the underlying host system which also ensures direct access to the host hardware which is why it does not require base OS.
2. Hosted Hypervisor: This type makes use of the underlying host operating system which has the existing OS installed.
5. What can you tell about Docker Compose?
It is a YAML file consisting of all the details regarding various services, networks, and volumes that are needed for setting up the Docker-based application. So, docker-compose is used for creating multiple containers, host them and establish communication between them. For the purpose of communication amongst the containers, ports are exposed by each and every container.
