What is virtualization?
Imagine you have a powerful computer, but you want to run multiple different operating systems or applications on it without having to buy several physical machines. Virtualization lets you create virtual versions of computers, servers, storage devices, and even networks. These virtual versions, called Virtual Machines (VMs), act like real hardware but are actually just software running on your physical computer.
With virtualization, you can run multiple operating systems (like Windows, Linux, or macOS) simultaneously on the same physical machine. Each operating system runs in its own isolated virtual machine, so they don’t interfere with each other. This ability to divide a single physical resource into multiple, separate virtual entities is what makes virtualization so powerful and transformative.
It’s important to note that virtualization differs significantly from cloud computing. While both concepts revolve around optimizing the use of computing resources, cloud computing is a broader methodology that encompasses the delivery of hosted services over the internet.
The benefits of virtualization
The adoption of virtualization technology can bring a multitude of benefits for businesses, each contributing to a more efficient, secure, and cost-effective IT infrastructure:
- Cost savings: By reducing the need for physical hardware, businesses can significantly cut down on capital expenditures. It leads to lower energy consumption as fewer physical machines are running, which translates to reduced operating costs.
- Operational efficiency and flexibility: Virtualization enhances operational efficiency by allowing IT teams to deploy, manage, and scale resources with unprecedented speed and flexibility. This agility is crucial in today’s fast-paced business environment, where the ability to adapt and respond to changing needs is a competitive advantage.
- Improved security: With virtualization, each virtual machine is isolated from the others, providing an additional layer of security. This isolation helps in containing security breaches to a single virtual machine, rather than affecting the entire physical server.
- Better resource allocation: Virtualization enables more efficient allocation of resources. It allows for the dynamic distribution of computing resources based on demand, ensuring that each application or service has access to the resources it needs when it needs them.
- Streamlined IT management: Managing a virtualized environment can be significantly simpler and more efficient than managing a traditional physical setup. Virtualization platforms often come with tools that automate many routine tasks, reducing the workload on IT staff and minimizing the risk of human error.
- Environmental benefits: A virtualized IT infrastructure is inherently more environmentally friendly. With fewer physical servers required, there’s a smaller physical footprint, which means less energy consumption and less waste.
While the benefits are compelling, it’s important to acknowledge that virtualization can introduce increased complexity in managing virtual environments and may require specific technical expertise. However, with strategic planning and professional implementation, these potential drawbacks can be effectively mitigated.
How does virtualization work?
Hypervisors
At the heart of virtualization is a specialized software known as a hypervisor. This software creates a layer of abstraction between physical and virtual components, allowing for the deployment of multiple cloud instances or VMs on a single physical component.
The hypervisor manages the relationship between virtual machines or cloud instances and the underlying hardware. It is tasked with the crucial role of coordinating the sharing of physical resources among multiple software machines, ensuring an efficient and dynamic distribution.
There are two main categories of hypervisors:
- Type 1 hypervisors, also known as bare-metal hypervisors, run directly on the physical hardware. They are renowned for their efficiency as they interact directly with physical resources.
- Type 2 hypervisors, in contrast, operate as applications within an existing operating system. This setup is ideal for running multiple operating systems on the same machine but is less efficient than Type 1 due to the additional layer of the host OS.
Virtual machines
Virtual machines can emulate anything from a server to a network or a storage device. Each VM typically includes configuration files, virtual storage, and a snapshot feature, allowing the VM’s state to be preserved at any given moment. Most importantly, VMs run their own operating systems, which may or may not be the same as the host’s OS.
The different facets of virtualization
Virtualization is not a monolith; it targets various physical hardware components, each with its own set of benefits and use cases:
- Server virtualization: This type allows multiple independent virtual servers to operate on a single physical server. It addresses the inefficiency of underutilized servers by partitioning a physical server into several virtual ones, optimizing resource use, and reducing hardware costs.
- Storage virtualization: By creating a unified storage network, storage virtualization facilitates the assignment of storage space between VMs as needed. This approach simplifies resource management, enhances capacity utilization, and streamlines data migration processes.
- Network virtualization: This abstracts the hardware elements of a network into a single software space. It simplifies network management, boosts security, and accelerates setup times, as modifications can be made within the software without altering the physical hardware.
- Data virtualization: Given the daily accumulation of vast data amounts in various formats, data virtualization provides a flexible and real-time integration solution. It allows applications to access data from any storage device, regardless of the format, enhancing efficiency in data management.
- Application virtualization: This technology enables applications designed for different operating systems to run in a virtualized environment on a device or server. Whether through local application virtualization, application streaming, or server-based application virtualization, this approach improves compatibility and eases application management.
- Desktop virtualization: Facilitating the operation of multiple desktop operating systems on a single computer, desktop virtualization enhances flexibility and access. Users can access their desktop environments remotely, from any location, through virtual desktop infrastructure or local desktop virtualization.
There are other forms, such as CPU or GPU virtualization. Additionally, cloud computing, which heavily relies on virtualization technology, offers various deployment models that further expand the scope of virtualization’s application. Liquid Web’s guide on cloud computing architecture provides a deeper dive into cloud computing and its types.
The difference between server virtualization and containerization
While server virtualization and containerization share similarities in enhancing efficiency and flexibility, it’s necessary to understand their distinct purposes and applications.
| Server virtualization | Containerization |
| Involves replicating a physical server into a VM, each running its own operating system. | Encapsulates an application and its dependencies into a single package or container. |
| Aims to maximize hardware utilization by allowing multiple VMs to operate on a single physical server. | This container can run across any physical or virtual environment without requiring changes, ensuring consistency regardless of the underlying infrastructure. |
| Provides an infrastructure-wide solution, making it possible to optimize resources and reduce hardware requirements across the entire data center. | Celebrated for its speed and efficiency, particularly in deploying and scaling applications. |
| Can be complex and may take longer to deploy compared to containerization. | Focuses specifically on the application layer, making it an excellent choice for microservices architectures and DevOps practices. |
| Better suited for scenarios requiring comprehensive infrastructure optimization and resource consolidation. It provides a more generalized solution that can lead to significant cost savings and efficiency improvements over time. | Ideal for rapid development and deployment cycles, especially when working with multiple microservices that need to operate independently. |
