We all know that Server and Storage virtualisation reduces the datacentre footprint, reduces capex expenditure and IT operational costs but it has evolved over the years and now also improves business continuity, resilience, can assist in disaster recovery preparations and improves automation.
Desktop virtualisation is on route to mainstream adoption, it can help manage your user device evolvement more efficiently, effectively and securely. Network virtualisation can consolidate multiple physical networks into a single virtual network and a single physical network into multiple logical networks, as a result, companies can improve network efficiency, enhance agility, reduce capex and operation costs and simplify manageability, security, scalability and availability.
Virtualisation is not all about cost reduction, by digitising, you can also provide much greater capability for the provision of IT services, especially in the context of high availability and business continuity.
- Device Consolidation
- Rapid Deployment
- Reduce infrastructure
- Business Continuity
- Reduced Operating Costs
- Increase flexibility
- Automated Disaster Recovery
- Easy Management
Types of virtualisation
Desktop Virtualization - Deploying desktops as a managed service enables IT organizations to respond faster to changing workplace needs and emerging opportunities.
Application Virtualization - Allows users to access and use an application from a separate computer than the one on which the application is installed. Using application virtualization software, IT admins can set up remote applications on a server then deliver the apps to an end user’s computer.
Server Virtualization - It starts with a physical server host where multiple server operating systems can be run as guests. This is a software architecture focused on delivering more efficiency where IT resources are concerned. It removes the potential for any data center to harbour inefficiencies, such as under (or over) utilized hardware). One physical server can balance load between different virtual machines and run a whole range of operating systems and configurations with efficiency as the goal.
Network Virtualization - allows network functions, hardware resources, and software resources to be delivered independent of hardware—as a virtual network. It can be used to consolidate many physical networks, subdivide one such network, or connect virtual machines (VMs) together.
Storage Virtualization - It provides the opportunity to pool devices from a range of vendors and networks, ensuring that they appear like one storage pool. The virtualization engine functions to combine the storage capacity from multiple arrays and storage media so that it can be effectively managed and presented to applications.
How virtualisation works
Virtualisation software simulates hardware functionality and creates multiple virtual computer systems. This enables organisations to use multiple applications and operating systems on a single server.
Virtualisation is used to efficiently manage and allocate resources to virtual machines. If a virtual machine were to crash, it would have no effect on the server, physical hardware or other virtual machines.
Virtualisation vs Containers
Both containers and virtual machines (VMs) are software technologies that create self-contained virtual packages. Beyond that commonality, they differ in their operations, characteristics and use cases.
You only need one machine or server. Thanks to virtualization you can run a range of operating systems via that server’s hardware and use containerization to deploy many different applications via the same operating system on that one server or machine.
