Types of Server Virtualization

When it comes to server virtualization, there are three main types that businesses can choose from: full virtualization, para-virtualization, and OS-level virtualization. Each type offers unique capabilities and benefits, catering to different needs and requirements.

Full Virtualization

Full virtualization utilizes a hypervisor, a software layer that emulates a complete physical computer. This allows multiple operating systems to run on a single physical server without any modification. The hypervisor allocates and manages resources, creating virtual machines (VMs) that function independently from each other and the host system. Full virtualization offers high flexibility and isolation, making it suitable for a wide range of workloads and operating systems.

Para-virtualization, on the other hand, requires a modified guest operating system (OS) that interacts with the hypervisor directly. By eliminating the need for complete hardware emulation, para-virtualization offers improved performance compared to full virtualization. It allows the guest OS to communicate directly with the hypervisor and enables faster I/O operations and lower virtualization overhead. However, para-virtualization requires the use of specific guest OS versions that have been modified to support this virtualization technique.

OS-level Virtualization

OS-level virtualization, also known as containerization, operates at the operating system level rather than virtualizing the whole hardware. It shares the host operating system among multiple containers, each running its own isolated applications. Containers provide lightweight virtualization, enabling faster startup times, efficient resource utilization, and improved scalability. This type of virtualization is particularly suitable for deploying and managing microservices and cloud-native applications.

Let’s compare these types of server virtualization in a table:
