What is Server Virtualization? A Complete A-Z Guide for Beginners

Server virtualization has become a crucial technology in managing IT infrastructure. By allowing multiple operating systems to run on the same hardware, virtualization enhances performance, saves costs, and improves flexibility. In this article, we will provide detailed insights into the concept of server virtualization, including its prominent benefits, popular software, and guidelines to help you implement this technology.

What is Virtualization?

Virtualization is a technology that allows you to run multiple computers or different operating systems on a single piece of hardware. For example, you can have both Linux and Windows running on the same computer, or even two different versions of Windows, like Windows 95 and Windows XP, on one machine.

In simple terms, virtualization separates the software and applications you use from the specific hardware they run on. This makes it easier to upgrade systems, as you can transfer the entire state of a virtual machine (VM) from an old computer to a new one without much hassle.

Virtualization also leads to more energy-efficient computing by allowing resources like processors, memory, and storage to be allocated more flexibly and precisely, rather than being tied to fixed hardware setups. This technology is driving new innovations in both hardware and software, making computing more powerful and efficient.

Understanding Virtualization: A Deep Dive into Information & Production Systems

Information Systems

In information systems, by abstracting system resources, it is possible to absorb differences in OS and hardware so that the same program can be run even on different OS and hardware. This is called ensuring portability. Also, when running multiple programs at the same time, try to run the programs without being aware of each other’s programs. Such techniques are very important for multitasking operating systems and servers that run multiple pieces of software on a single piece of hardware.

Especially in servers, system resources such as memory occupancy and CPU occupancy are often surplus, so it is conceivable to install multiple server software on one hardware to make effective use of resources. However, depending on the server software, the operating environment, users, and required security level may differ, and it may not be possible to operate on one piece of hardware at the same time. Therefore, there are many cases where virtualization software is installed on the server. By introducing virtualization software, different software can operate independently at the same time without being aware of each other’s operating conditions.

Benefits of Virtualization in Information Systems

The advantage of virtualization is, after all, the freedom of the system. For example, portability allows existing software to run on different operating systems and new hardware. It is also possible to run multiple programs at the same time without being aware of the behavior of each other’s programs. This can reduce the total cost of the system, which is often especially useful for servers.

On the other hand, the disadvantage is that the virtualization mechanism becomes complicated and slows down. Therefore, when building a system with virtualization in mind, sufficient hardware capacity is required. Next, let’s look at a concrete example of virtualization technology. 

MVS
MVS (Multiple Virtual Storage) is an OS for mainframes developed by IBM, but it is known as the fastest and most practical operating system in the world. Virtual memory is a technology that can be called “memory space virtualization,” and is an indispensable technology for multitasking OSs. For example, suppose multiple programs are running at the same time when virtual memory is not supported. In this environment, suppose program A writes data X to a memory space. Then what happens if program B writes data Y to the same memory space? After that, even if program A tries to read the data, it will read the data Y, and the data will not be consistent, so program A will not work properly.

Therefore, before program B writes data Y by MVS, data X is saved in an external storage device. It then returns the data X to memory before program A reads it. The principle of virtual memory is to perform this operation so that programs A and B are not aware of it. This allows the program to run independently, regardless of the behavior of other programs.

Java VM
Java is a programming language, but at the same time it has the aspect of a “virtual machine”. As a general rule, the Java compiler does not output native code (code that can be directly executed by the CPU), but outputs intermediate code. This intermediate code is a form of code that can be executed by the Java VM (Java Virtual Machine). Intermediate code is slower to execute than native code, but even if the OS and hardware configuration are different, if you prepare a Java VM for that OS and hardware, you can execute common intermediate code.

There are various types of OSs for embedded systems for different purposes, and it is often easier to develop a Java VM than to prepare a compiler for all OSs. JavaVM has the advantage of absorbing differences in OS and hardware and executing common intermediate code. For this reason, Java is often used in embedded systems.

WINE

“WINE” is software that runs Windows applications on Linux. It’s a type of emulator that goes between Linux and Windows applications and acts as a bridge between APIs (application programming interfaces). From the perspective of absorbing OS differences, this type of emulator can be said to be one of virtualization.

Production Systems

Virtualization, on the other hand, in production systems is a relatively new concept that has recently come into use. Basically, it is “hiding and abstracting the technical details of the system”, but it is a feature that these abstractions are performed by IT technology.

Specifically, it is to reproduce the production line of the factory on a computer and simulate the movement, yield, layout, etc. of the worker before actually constructing the production line. It also includes using IT equipment to control production lines and control production. So to speak, it can be said to “virtualize” the production line via IT equipment.

Benefits of Virtualization in Production System 

On the other hand, what are the benefits of virtualizing production systems?

By reproducing the production line of the factory on a computer and simulating the production line, it is possible to examine and improve various problems before actually starting production. It is also possible to improve production efficiency and save labor by managing production using IT equipment.

When virtualizing production systems, especially monitoring and production control using IT equipment, the problem is that the control protocols and data formats of manufacturing equipment are different. Manufacturing equipment manufacturers often employ optimal control protocols and data formats to maximize the performance of their manufacturing equipment. There is a movement to create these unified standards, but the current situation is that they have not been realized yet.

Therefore, it is conceivable to introduce an edge server between the control system of the manufacturing equipment and the cloud server and perform operations on the edge server to absorb these differences. That way, from the perspective of the cloud server, the data formats and control protocols all look the same. Therefore, such a system may also be called “virtualization” in the sense that it absorbs the differences between manufacturing equipment. Introducing edge computing for this purpose has the advantage of achieving both monitoring and speed of manufacturing equipment.

In addition, if the edge server itself is virtualized, multiple manufacturing devices can be monitored independently with a single piece of hardware for the edge server, and software can be added later. This will also reduce running costs.

Future trends in virtualization technology

Automation of the Workplace: Many industries are replacing manual processes with automated systems to boost efficiency. For instance, logistics management and building automation now use technology to handle tasks more smoothly. As more businesses adopt automation, keeping servers up and running becomes crucial.

Self-Service Applications: Consumers are increasingly used to managing their own shopping experiences online. In 2012, U.S. e-commerce sales were $289 billion, and by 2016, they were projected to reach $361.9 billion. Businesses rely on servers to handle many customers simultaneously. If these servers fail, businesses lose sales and customer satisfaction drops.

Mobile Device Connectivity: Employees and consumers need access to data and services from their mobile devices, whether they are working remotely or on the go.

What is Server Virtualization?

Server virtualization is a technology that allows multiple operating systems to run simultaneously on a single physical server. This is achieved by creating virtual instances of servers, called virtual machines (VMs), on the physical hardware. Each VM has its own dedicated resources, such as CPU, memory, and storage, making it appear as a separate physical server to the applications running on it.   

Types of Server Virtualization

There are three main types of server virtualization: operating system virtualization; hardware emulation; and paravirtualization, a relatively new concept designed to deliver a lighter weight (in terms of application size), higher performance approach to virtualization.

Operating system virtualization

 

Operating system (OS) virtualization (sometimes called containers) runs on top of an existing host operating system and provides a set of libraries that applications interact with, giving an application the illusion that it is (or they are, if there are multiple applications) running on a machine dedicated to its use. The key thing to understand is that, from the application’s execution perspective, it sees and interacts only with those applications running within its virtual OS, and interacts with its virtual OS as though it has sole control of the resources of the virtual OS. Crucially, it can’t see the applications or the OS resources located in another virtual OS.

Advantages

This approach to virtualization is extremely useful if you want to offer a similar set of operating system functionalities to a number of different user populations while using only a single machine. This is an ideal approach for Web hosting companies: They use container virtualization to allow a hosted Web site to “believe” it has complete control of a machine, while in fact each hosted Web site shares the machine with many other Web sites, each of which is provided its own container. Operating system virtualization imposes little overhead for the virtualization capability, thereby ensuring most of the machine’s resources are available to the applications running in the containers.

Disadvantages

There are some limitations to operating system virtualization, though. First and foremost, this approach typically limits operating system choice. Containerization usually means that the containers offer the same operating system as the host OS and even be consistent in terms of version number and patch level. As you can imagine, this can cause problems if you want to run different applications in the containers, since applications are often certified for only a certain OS version and patch level. Consequently, operating system virtualization is best suited for homogenous configurations — for those arrangements operating system virtualization is an excellent choice.

Hardware emulation

Virtual Machine Monitor 

In hardware emulation, the virtualization software (usually referred to as a hypervisor) presents an emulated hardware environment that guest operating systems operate upon. This emulated hardware environment is typically referred to as a virtual machine monitor or VMM.

The VMM provides a standardized hardware environment that the guest OS resides on and interacts with. Because the guest OS and the VMM form a consistent package, that package can be migrated from one machine to another, even though the physical machines the packages run upon may differ. The hypervisor, which resides between the VMM and the physical hardware, translates the calls from the VMM to the specific resources of the physical machine.

This approach to virtualization means that applications run in a truly isolated guest OS, with one or more guest OSs running, one per VMM. The VMMs all reside on the virtualization hypervisor. Not only does this approach support multiple OSs, it can support dissimilar OSs, differing in minor ways (for example, version and patch level) or in major ways (for example, completely different OSs like Windows and Linux can be run simultaneously in hardware emulation virtualization software).

Advantages

Common applications for hardware emulation are software development and quality assurance, because it allows a number of different OSs to be run simultaneously, thereby facilitating parallel development or testing of software in a number of different operating system environments. Hardware emulation is also used in server consolidation, where a number of operating system/application environments are moved from separate physical servers to a single physical server running virtualization software.

Disadvantages

There are a couple of drawbacks to hardware emulation, however. One is that the virtualization software hurts performance, which is to say that applications often run somewhat slower on virtualized systems than if they were run on unvirtualized systems.

Another drawback to hardware emulation is that the virtualization software presents a standardized hardware interface (the VMM) to the guest operating system. The hypervisor provides an interface to the VMM and then translates that into calls to the actual physical resources on the machine. This means that the hypervisor must contain the interfaces to the resources of the machine; these resources are referred to as device drivers. If you’ve ever installed new hardware in a PC, you know that you often have to install a device driver into the operating system so that the new hardware and the operating system can communicate. 

The device driver issue for hardware emulation is that the hypervisor contains the device drivers and there is no way for new device drivers to be installed by users (unlike on your typical PC). Consequently, if a machine has hardware resources the hypervisor has no driver for, the virtualization software can’t be run on that machine. This can cause problems, especially for organizations that want to take advantage of new hardware developments.

 Paravirtualization

Paravirtualization is the name for another approach to server virtualization. In this approach, rather than emulate a complete hardware environment, the virtualization software is a thin layer that multiplexes access by guest operating systems to the underlying physical machine resources.

Advantages

There are two advantages to this approach. First, it imposes less performance overhead because it is a very small amount of code. Hardware emulation, you’ll recall, inserts an entire hardware emulation layer between the guest operating system and the physical hardware. By contrast, paravirtualization’s thin software layer acts more like a traffic cop, allowing one guest OS access to the physical resources of the hardware while stopping all other guest OSs from accessing the same resources at the same time.

The second advantage of the paravirtualization approach compared to hardware emulation is that paravirtualization does not limit you to the device drivers contained in the virtualization software; in fact, paravirtualization does not include any device drivers at all. Instead, it uses the device drivers contained in one of the guest operating systems, referred to as the privileged guest. Without going into too much detail about this architecture here, suffice it to say that this is a benefit, since it enables organizations to take advantage of all the capabilities of the hardware in the server, rather than being limited to hardware for which drivers are available in the virtualization software as in hardware emulation virtualization.

Disadvantages

It might seem that paravirtualization would be the way to go. However, there has been one significant drawback to this approach to virtualization: Because it is lightweight and multiplexes access to the underlying hardware, paravirtualization requires that the guest operating systems be modified in order to interact with the paravirtualization interfaces. This can only be accomplished by having access to the source code of the guest operating system. This access is possible for open source operating systems like Solaris and Linux, and is only possible for Microsoft operating systems with Microsoft source code access.  

How does Server Virtualization work

Server virtualization works by creating multiple virtual servers, or virtual machines (VMs), on a single physical server. This is achieved through the use of virtualization software, also known as a hypervisor. Here’s a breakdown of how server virtualization works:

• Hypervisor: The hypervisor is a software layer that sits between the physical server hardware and the virtual machines. It manages the allocation of resources like CPU, memory, storage, and network among the virtual machines.   
• Virtual Machines: Each virtual machine is a self-contained environment that can run its own operating system and applications. It appears to the guest operating system as a physical server with its own dedicated resources.   
• Resource Allocation: The hypervisor allocates resources to the virtual machines based on their needs and priorities. It can dynamically adjust resource allocation to ensure optimal performance and utilization.   
• Isolation: Each virtual machine is isolated from the others, preventing interference and ensuring security. This allows organizations to run multiple workloads on a single physical server without compromising their integrity.   
• Management: The hypervisor provides tools for managing the virtual machines, including creating, modifying, and deleting them. It also allows for monitoring resource usage and performance.

Benefits of Server Virtualization

Server virtualization offers numerous advantages for businesses and organizations, addressing both financial and technical concerns.

Space Efficiency Through Consolidation: Traditionally, servers were dedicated to single applications, which could lead to underutilization of resources. Server virtualization allows multiple virtual environments to run on a single physical server. This consolidation significantly reduces the physical space required, particularly beneficial for organizations with extensive server farms.

Enhanced Redundancy: Server virtualization enables redundancy without the need for extra physical hardware. By running the same application on multiple virtual servers, companies can ensure continuity if a server fails. Instead of duplicating hardware, redundant virtual servers are typically spread across different physical machines, reducing the risk of simultaneous failure.

Isolated Testing Environments: Virtual servers provide isolated environments for developers to test new applications or operating systems. Rather than investing in additional physical machines, administrators can set up virtual servers on existing hardware, allowing safe experimentation without impacting other systems.

Extending Legacy Systems: As server hardware becomes outdated, transitioning to new systems can be challenging. Virtualization allows for the creation of virtual versions of legacy hardware on modern servers, enabling legacy applications to run seamlessly. This approach facilitates a gradual transition to newer processes while maintaining functionality.

Server Migration: Migration is an emerging trend in server virtualization, referring to the movement of a server environment from one location to another. Advanced hardware and software now allow virtual servers to migrate between physical machines with different processors, provided they are from the same manufacturer. This capability enhances flexibility and resource optimization across a network.

The Risks of Virtualization and How to Mitigate

Virtualization, while offering numerous benefits, also introduces new risks that organizations must carefully consider. Explore some of the key risks associated with virtualization and provide strategies to mitigate them.

The Risks of Virtualization

• Single Point of Failure: A hypervisor failure can lead to the collapse of all virtual machines running on it, resulting in significant downtime and data loss.
• Performance Degradation: Overloading a physical server with too many virtual machines can cause performance bottlenecks and impact application responsiveness.
• Security Vulnerabilities: Virtualization environments can introduce new security risks, such as hypervisor attacks and escape vulnerabilities.
• Complexity and Management Challenges: Managing a complex virtualization environment can be time-consuming and error-prone.
• Data Migration and Compatibility Issues: Migrating virtual machines between different virtualization platforms or hardware can be challenging and may require compatibility testing.

How to Mitigate Risks of Virtualization  

• Redundancy and High Availability: Implement redundant hypervisors, storage systems, and network components to minimize downtime in case of failures. Consider using high availability clustering technologies to automatically fail over virtual machines to redundant hosts.
• Performance Monitoring and Optimization: Continuously monitor the performance of virtual machines and physical servers to identify and address potential bottlenecks. Optimize resource allocation and consider using tools for automated performance management.
• Robust Security Measures: Implement strong security practices, including regular patching, access controls, and intrusion detection systems, to protect virtualization environments from attacks.
• Effective Management Tools: Use virtualization management software to automate tasks, simplify administration, and improve visibility into the environment.
• Disaster Recovery Planning: Develop a comprehensive disaster recovery plan to ensure that you can recover virtual machines and data in case of a major outage.
• Vendor Selection and Support: Choose a reputable virtualization vendor with a strong track record and reliable support services.

Best practices for server virtualization

Discover how to benefit from server virtualization while avoiding mistakes that could affect  availability and performance of mission-critical manufacturing IT applications

Know your application

Begin by characterizing your software application and its workload correctly. Which resources does your application consume? How much? When? How much headroom do you need for peak times and temporary surges in demand? In the event of performance degradation, the application could become unavailable and provide poor response time to users or processes.Also conduct an appropriate risk assessment. Even if you’re starting with noncritical applications, the server on which you’re consolidating them often becomes essential when it drives numerous applications. In addition, not every application is a good candidate for virtualization. Typical examples are I/O-heavy applications and performance-sensitive environments that aren’t charac-terized easily.

Understand trade-offs

Because virtual servers are easy to set up and don’t require the same management approval as hardware purchases, trade press articles report that some companies are experi-encing “virtual server sprawl.”

Expect some performance penalty too; how much depends on your application and the virtualization technology you use. What’s more, maximizing application availability and performance on a virtual machine requires considerable skill. 

In addition, you need to understand how virtualization will affect your software license fees.

Seek enterprise-strength technology

Remember, the virtualization layer has the potential to be a single point of failure for all of the virtual machines it supports. One rule of thumb: Software reliability increases as the amount of code and its complexity decrease.

Look for virtualization software that’s small, compact and controlled — and as appliance-like in nature as pos-sible. Virtualization and availability solutions that are sim-ple to configure and maintain provide crucial advantages by reducing operating cost and by significantly reducing your exposure to downtime caused by operational errors.

Plan for business continuity

Reliable availability and performance become more important the more you depend on an IT resource, and the more that resource is integrated with other systems. To mitigate the risk of plant operations being interrupted, institute backup and disaster recovery measures for the physical servers that run your virtual machines.

Simplify with robust hardware

Virtualization subtracts physical complexity, but adds equally real complexity in a virtual dimension. Without proper planning, this can be an issue because IT skills are in short supply at the average manufacturing facility.

Clustering multiple servers is one technique for achiev-ing high availability. Implementing virtualization on a server cluster adds another layer to deploying and admin-istering a cluster, on top of the ongoing attention from IT staff that’s already necessary. 

For instance, a server must be running to migrate its workload to another member of the cluster. Therefore, when a double-bit memory fault causes a server to crash, its workload can’t be transferred, data will probably be lost and a reboot will be necessary. With clustering, you can expect to incur performance overhead in any case.

Server hardware or virtualization software vendors might claim they achieve high availability by predicting hardware faults and by enabling live migration of ap-plications to backup servers. They also might assert that applications can be quickly restarted on another server. Ask which hardware faults can be predicted enough in advance to support a live migration. What percentage of the hardware is covered? In the case of a full restart, what is the worst-case fault detection and restart time? Is the management software making fail-over decisions robust, or for that matter, running on a robust platform? 

For simplicity’s sake, consider a fault-tolerant server that automatically protects reliability and availability without requiring changes to your business-critical application. This approach uses redundant components while appearing as a single server to virtualization and application software. Ide-ally, the emphasis should be on preventing downtime and data loss instead of simply on quick recovery.

Don’t let I/O sink the ship

Incompatibilities related to I/O interfaces are a known cause of system instability and performance problems. Establish that I/O devices and drivers are compatible with the virtualization technology you plan to use. 

Be ready, willing and able to resolve incompatibilities up front if you need to use legacy or proprietary I/O cards to ac-cess specialized plant equipment networks, which is common with supervisory control and data acquisition (SCADA).

Don’t go it alone

Virtualizing in a manner that promotes the availability and performance of business-critical applications requires con-siderable expertise. This goal isn’t realistic without a knowl-edgeable staff or a trusted professional services provider.

Key Cost Considerations for Server Virtualization

When considering virtualization software, cost is a significant factor to weigh. While virtualization can offer numerous benefits, it’s important to understand the potential expenses involved. Here are some key cost considerations:

Direct Costs

• Hardware: While virtualization can often reduce the need for additional physical servers, you may still require more powerful hardware to handle the increased workload. Factors to consider include processor cores, RAM, and storage capacity.
• Software: Virtualization software, such as VMware vSphere, Hyper-V, or Stratus zero-touch computing, typically comes with licensing costs. These costs can vary depending on the number of virtual machines (VMs) you plan to run and the features required.
• Storage: Virtualized environments often rely on shared storage solutions, like SANs or NASs. These can be expensive, especially for large-scale deployments.

Indirect Costs

• Maintenance: Managing a virtualized environment requires specialized skills and tools. You may need to invest in additional staff or training to ensure optimal performance and security.
• Energy Consumption: While virtualization can improve resource utilization, it’s important to consider the energy consumption of the physical servers and storage systems. Efficient hardware and virtualization software can help mitigate these costs.
• Downtime: Virtualization can help reduce downtime, but unexpected failures or configuration errors can still occur. Implementing robust backup and disaster recovery strategies is crucial to minimize the impact of such events.

Factors to Consider

• Return on Investment (ROI): Calculate the potential savings from reduced hardware costs, improved resource utilization, and increased flexibility.
• Scalability: Assess how well the virtualization solution can accommodate future growth and changes in workload.
• Disaster Recovery: Consider the impact of virtualization on disaster recovery planning and costs.
• Security: Implement robust security measures to protect the virtualized environment from threats.
