Virtualisation is a technology that allows a single physical server to "host" multiple "guest" operating systems on a single piece of hardware in completely isolated containers.
Installing traditional physical servers would typically require a separate physical server for each server role. Utilising virtual server technology (such as VMware ESX or Microsoft Hyper V) the number of physical servers can be greatly reduced as server roles are consolidated down onto fewer physical servers. Virtualisation will result in improved resource utilisation and lower capital expenses due to more efficient uses of hardware resources.


Advantages of virtualisation

High Availibility

High Availability



As all of the business workloads are "virtual servers" that operate on top of physical host server systems, these "guests" can be moved between hosts. This migration can be done online - allowing the production workloads to be migrated between physical hosts with zero downtime. This portability brings benefits in allowing maintenance to be performed on the physical host serves with zero impact to business operations.   A virtualised platform is highly scalable, meaning that a client can start small and expand as required by adding additional physical servers. As less physical hardware is required over time as your business grows and expands, you can save significantly on server procurement and management costs

Disaster Recovery & Fault Tolerance

  Reduced Expences

Reduced Capital Expenditure

Due to the portable nature of guest Virtual Machines, they are easily able to survive host server failures with very minimal downtime. In a properly deployed environment, the virtual workloads of a host server that fails can be automatically restarted on any remaining host servers in the event of a host failure. This feature is completely automated, with the management server closely monitoring a heartbeat of the host servers to quickly identify any issues and restart affected virtual machines as quickly as possible to ensure minimal downtime.            By consolidating many physical server workloads into virtual machine guests running on a fewer physical host servers, We Manage to deliver the benefits of reduced capital expenditure in the short term by dramatically reducing the number of physical servers required. Furthermore, organisations that deploy virtualised environments also reduce their energy consumption leading to a reduced carbon footprint and improve the effectiveness of their disaster recovery plan.
