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 - Allows more than one server operating system to run as a guest on a given physical server host. This enables more efficient use of IT resources than was previously possible; one can move workloads between virtual machines according to load. The same physical server can also run multiple server operating systems and configurations, further increasing efficiency.
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 - This runs on multiple storage devices, making them appear as if they were a single storage pool. Pooled storage devices can be from different vendors and networks. The storage virtualization engine identifies available storage capacity from multiple arrays and storage media, aggregates it, manages it and presents it 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.
Virtualisation enables you to run multiple operating systems on the hardware of a single physical server, while containerization enables you to deploy multiple applications using the same operating system on a single virtual machine or server.
