VMware vs VirtualBox: Picking the Right Hypervisor for Virtualisation

In today’s fast-paced world, where technology is evolving at an unprecedented rate, virtualization has emerged as a game-changing concept in software development and IT infrastructure. It has revolutionized how we deploy, manage, and utilize computing resources, making it an indispensable tool in the modern digital landscape. Virtualization has become the norm for software and operating system testing.

In this blog post, we’ll embark on an exploration & detailed comparison of the two most popular hypervisors, VMware vs VirtualBox (Oracle), to understand their strengths, differences, and how they contribute to virtualization Technology.

With the enterprise-grade capabilities of VMware & simplicity and the cost-effectiveness of VirtualBox, the two dominate the world of virtualization. Both platforms are reliable but possess some distinct differences which make the comparison interesting.

 Do you know that around 80 per cent of the X86 server workloads are virtualized and the average server can run 16 simultaneous VMs.

Demystifying Virtualisation for Beginners

A technical definition of virtualization would be to create a virtual (not actual or physical) instance of something. Imagine a single physical computer acting as a host, capable of running multiple operating systems and applications concurrently. These individual instances, called virtual machines (VMs), function as isolated entities, unaware of the presence of others.

Virtualization allows for the allocation of hardware resources, such as CPU, memory, and storage, to each VM, creating a virtualized environment that operates independently of the underlying physical infrastructure. This enables organizations and developers to maximize their hardware utilization, enhance security and isolation, and streamline software development, testing, and deployment processes.

Virtual Machines (VMs)

A virtual machine (VM) is a software emulation of a physical computer system, allowing multiple operating systems to run simultaneously on a single physical machine. Each VM operates independently, with its own virtualized hardware resources, including CPU, memory, storage, and network interfaces. It provides an isolated environment that mimics the behavior of a dedicated physical machine, enabling users to install and run applications as if they were on separate physical computers.

VMs bring a range of benefits to software development and IT infrastructure. They enhance hardware utilization by consolidating multiple VMs onto a single physical host, reducing costs and energy consumption.

VMs also provide portability, as they can be easily migrated between different hosts or deployed in cloud environments. Additionally, VMs offer enhanced security by isolating applications and operating systems, preventing potential conflicts, and mitigating the impact of malware or system failures.

Hypervisors

At the core of virtualization technology lies the hypervisor, also known as a virtual machine monitor (VMM). A hypervisor is responsible for creating and managing virtual machines, serving as an intermediary between the physical hardware and the virtualized operating systems.

There are two primary types of hypervisors:

Type 1 Hypervisors (Bare-Metal Hypervisors):

Type 1 hypervisors are installed directly on the physical hardware, eliminating the need for an underlying operating system. They have direct control over the hardware resources and provide high performance and scalability. Examples of Type 1 hypervisors include VMware ESXi, Microsoft Hyper-V, and Citrix XenServer.

Type 2 Hypervisors (Hosted Hypervisors)

Type 2 hypervisors are installed on top of a host operating system. They rely on the host OS to manage hardware resources and provide services to the virtual machines. Type 2 hypervisors are typically easier to install and use, making them suitable for personal or development environments. VirtualBox and VMware Workstation are examples of Type 2 hypervisors.

Understanding How Virtualization Works

Virtualization works by abstracting physical resources and creating virtualized counterparts that can be used by multiple virtual machines. The process can be summarized in the following steps:

  1. Hypervisor Installation: The hypervisor is installed on physical hardware or on top of a host operating system, depending on the type of hypervisor used.
  2. Creation of Virtual Machines: The hypervisor creates and manages virtual machines, allocating virtualized hardware resources to each VM, including CPU, memory, storage, and network interfaces.
  3. Resource Allocation: The hypervisor distributes the available physical resources among the virtual machines based on their configured settings and requirements.
  4. Isolation and Encapsulation: Each virtual machine operates independently, encapsulating the entire operating system and applications within its own isolated environment. This isolation ensures that changes or issues within one VM do not affect the others.
  5. Virtual Machine Operations: Users can power on, shut down, pause, resume, and migrate virtual machines as needed. The hypervisor manages these operations, ensuring the seamless execution of VMs across the physical infrastructure.
  6. Hardware Emulation: The hypervisor emulates the virtual hardware for each virtual machine, translating the instructions from the VM to the underlying physical hardware.

By leveraging virtualization, organizations, and developers can optimize resource utilization, improve flexibility, enhance security, and streamline IT operations.
