Two common types of virtualization technology are hypervisor-based virtualization and container-based virtualization. Hypervisor-based virtualization, also known as virtual machine (VM) virtualization, uses a hypervisor to create and manage virtual machines. Each VM runs its own operating system, which can be different from the host OS. The pros of this approach include strong isolation between VMs, which enhances security and stability. It also allows for running multiple different operating systems on the same hardware. However, the cons include higher resource overhead since each VM requires its own OS and associated resources, leading to potentially reduced performance and increased complexity in management.

Container-based virtualization, on the other hand, uses containers to virtualize at the OS level. Containers share the host OS kernel but run isolated user spaces. The pros of this approach include lower overhead because containers are lightweight and share the host OS, leading to better performance and efficient resource utilization. Containers also offer faster startup times compared to VMs. However, the cons include less isolation compared to VMs, which can pose security risks if a container is compromised. Both technologies have their unique advantages and trade-offs, and the choice between them depends on the specific needs and constraints of the deployment environment.
