Virtualisation has become an increasingly popular trend in data centre management. It allows for the efficient use of resources by creating virtual versions of physical computing components, such as servers, storage, and networks. This has enabled data centres to run multiple applications and services on the same hardware, resulting in greater efficiency and cost savings.
The major virtualisation technologies in data centres can be divided into two categories: server virtualisation and desktop virtualisation. This article will give an overview of the major virtualisation technologies in data centres, including a brief introduction to each brand, their history, ownership and a link to the corporate website, as well as any data from recognised sources giving pros and cons, market share etc.
1. VMware: VMware is the world leader in server virtualisation technology, with a market share of over 65%. It was founded in 1998 and is now owned by Dell Technologies. VMware provides a comprehensive portfolio of products to help organisations build, run and manage their digital infrastructure in a cost-effective and efficient manner. It offers a range of solutions for virtualised environments, including vSphere, vSAN, and NSX. Pros of VMware include its intuitive user interface, scalability, and robust security features. Cons include its high cost and the complexity of its solutions.
2. Microsoft Hyper-V: Microsoft Hyper-V is a virtualisation solution from Microsoft, which provides virtualisation infrastructure for Windows-based environments. It provides virtual machines, networking, storage, and clustering solutions for organisations. Hyper-V also offers an intuitive user interface, scalability, and a range of security features. Pros of Hyper-V include its cost-effectiveness and integration with other Microsoft products. Cons include its lack of support for Linux and other non-Microsoft operating systems.
3. Citrix XenServer: Citrix XenServer is a virtualisation solution from Citrix Systems. It provides a comprehensive suite of solutions for virtualised environments, including virtual machines, storage, networking, and security features. Pros of XenServer include its scalability, robust security features, and cost-effectiveness. Cons include its lack of support for Windows and its complexity.
Desktop virtualisation is a technology that allows organisations to create, manage and distribute virtual desktops, applications, and services. It enables organisations to deliver a secure, centrally managed computing environment to their users, enabling them to access all of their applications and data from any device, anywhere. Desktop virtualisation offers numerous benefits to businesses, including improved security, increased scalability, reduced IT costs, and improved user experience. It also enables organisations to manage their desktop environments more effectively, improving overall productivity.
1. Citrix XenDesktop: Citrix XenDesktop is a desktop virtualisation solution from Citrix Systems. It enables organisations to deliver virtualised desktops and apps to users on any device, with a range of features such as high-definition graphics, secure access, and seamless user experience. XenDesktop is a popular solution for organisations that need to run applications on multiple devices, such as in the office and at home. Pros of XenDesktop include its scalability and security features. Cons include its complexity and lack of support for Linux.
2. VMware Fusion: VMware Fusion is a desktop virtualisation solution from VMware. It enables organisations to deliver a consistent desktop experience to users on different devices, including PCs, Macs, tablets and phones. Fusion also supports multiscreen deployments, providing a single desktop experience across multiple screens. Pros of VMware Fusion include its ease of use and support for a wide range of devices. Cons include its low scalability and lack of security features.
3. Apple Mac OS X: Apple Mac OS X provides users with a desktop experience similar to what they would find on Windows or Linux systems, but without the cost or complexity associated with those platforms. Mac OS X can be used as the foundation for a Desktop Virtualization solution by running virtual machines on top of it. Pros of running virtual machines on top of Mac OS X include its ease of use and compatibility with other systems. Cons include its limited scalability and lack of support for different devices.
Network virtualisation is a technology that enables organisations to create multiple virtual networks within a single physical network. This technology offers a range of benefits to data centres, such as improved scalability and resource utilisation, increased flexibility and cost savings. Network virtualisation technology also provides enhanced security and better performance, as well as improved reliability and availability. By virtualising the network, organisations can create multiple logical networks within a single physical network, allowing for increased efficiency and better utilisation of resources. In addition, network virtualisation can be used to create virtualised networks that are isolated from each other, allowing for better security and improved performance. Network virtualisation technology also allows for easier management of the network, as organisations can create and manage one network instead of managing multiple physical networks. Overall, network virtualisation technologies provide numerous benefits to the data centre, making it an attractive option for organisations looking to improve their network infrastructure.
