Question 1

What is Server Virtualization Software?

Accepted Answer

Server virtualization products, commonly referred to as hypervisors, are used by organizations to partition dedicated servers into scalable virtual instances called virtual private servers (VPS). Virtual private servers created with server virtualization technology can each host a unique operating system and be managed independently through an integrated hosting control panel. Organizations use server virtualization products to allocate server resources among virtual machines for workload optimization. Virtual machines created with virtualization platforms are often more flexible and reliable to manage than unpartitioned servers. Organizations that house and manage servers internally implement server virtualization solutions to reduce resource strains. Additionally, virtualization technology is commonly used by hosting service providers to offer VPS hosting services to their customers. 
 What Types of Server Virtualization Software Exist? 
 All virtualization technologies will serve the purpose of dividing a server into unique, virtual servers. Still, there are general differences depending on the virtualized server the user intends to implement.  
 Full virtualization 
 Full virtualization typically requires a hypervisor that communicates with, monitors, and relays resources between applications and the physical server. This type of virtualization can limit performance since both the physical server and the hypervisor require processing power to operate. These virtualization platforms typically utilize a single operating system. For example, a Linux hypervisor would create a virtual Linux server to run applications. 
 Para-virtualization 
 Para-virtualization operates similarly to full virtualization, but it integrates the entire network and any other para-virtualized servers. This interoperability reduces the processing needs. 
 OS-level virtualization 
 OS-level virtualization is another type of server virtualization that preprograms an operating system, allowing different applications running different operating systems to utilize the same physical resources simultaneously. This adds additional flexibility and portability when developing in the cloud or migrating legacy systems.

Question 2

What are the Common Features of Server Virtualization Software?

Accepted Answer

The following are some core features within server virtualization that can help users deploy, manage, and optimize virtualization server software: 
 Scaling: Scaling features help companies ramp up usage as growth occurs. This is done by allocating host resources to create additional instances quickly without requiring additional physical infrastructure. 
 Portability: Portability features provide an efficient server and storage migration functionality. This allows users to move applications from one server to another without having to reconfigure the entire server or application 
 Data recovery: Backup and recovery features provide backup functionality to store and protect redundant data sets and protect and restore a database. Recovery features will help revert systems in the case information is deleted or destroyed. 
 OS integration: Operating systems may determine how flexible or how portable a server is. Proper host integration will ensure an application runs smoothly with a variety of operating systems such as Windows, Linux, etc. 
 Resource management: Resource management features help people optimize physical and virtual resources across complex computing environments to ensure efficiency and availability at all times.  
 Performance management: Performance management features monitor virtual environments and physical hardware performance. Typically this is presented through a single-pane-of-glass dashboard. 
 Multi-server management: Multi-server management features allow users to manage, monitor, and configure resources across numerous virtualized servers. This can allow users to track and control resource spend and loads across entire networks. 
 Hosting: Hosting services of VPS allow customers to host an account on virtualized servers. The overall server resources are shared across all accounts, while some portions of those resources are reserved for each account. 
 Control panel: In a VPS, a control panel integrates hosting plans with either open-source or proprietary web hosting control panels. This helps to provide customers with a graphical user interface (GUI) that facilitates access to additional web hosting management features. 
 Supported operating systems: Various operating systems have their strengths and weaknesses concerning performance, security, and integration. Some VPS offerings allow customers to choose from multiple supported operating systems while others only support one.

Question 3

What are the Benefits of Server Virtualization Software?

Accepted Answer

Cost savings: Physical servers are costly and present an expensive barrier to entry for some companies. Smaller businesses may not have the staff to manage on-premises servers at all times. Server virtualization technologies help to expand the functionality of servers without requiring more infrastructure. This saves money in a similar way to any “as a service” offering. Server virtualization can expand the reach and functionality of a single server to achieve numerous business goals.  
 Free time: Physical servers require substantial time and effort not only to implement but also to maintain throughout their usage lifecycle. These servers must remain secure at all times, monitored for anomalous activities, and optimized for peak performance. Without the need to manage numerous servers on premises, IT staff can be more focused on expanding functionality, ensuring availability, and everything else they do to keep the modern world connected. 
 Flexibility and portability: Server virtualization platforms make it easier for companies to change the way they utilize servers without inhibiting availability or increased costs. Most of the flexibility comes from the consolidation of servers onto a single server, as well as the ability to add additional virtual servers
