What is Virtualisation?
Virtualisation technology refers to the compartmentalisation and storage of operating systems, applications, and files on one server. This allows for the creation of many virtual servers within a single device. The outcome is that one physical server may act as many separate virtual servers with control over multiple work groups or networks.
Why Virtualisation? There are two major benefits of introducing virtualisation to a data centre:
- Centralised Multi-Network Management
Manage requests for access to your data across all network devices. Benefit from centralised software designed to monitor the performance of multiple virtual servers.
- Identify and Re-Assign Unused Storage
Scale up the availability of your network servers without the need for additional physical infrastructure. Process increased demands for data without compromising performance.
Virtualisation - Origins
Virtualisation began in the 60s as a means of “time sharing”. This was the name given to a network scenario in which multiple endpoint users could request access to different sets of data stored on the same servers (or more broadly, data centres).
Technology Marches On - 80s and 90s
The benefits of uploading applications and operating systems to the same “time shared” server were initially deemed to be both financial and practical. This is because virtualisation reduces the number of physical servers required to run your company, meaning less infrastructure is required. However, the growth in information technologies led to competition within the server market that disrupted the viability of existing virtualisation software.
Successful Implementation The idea of virtualisation remained strong and in 1999 a type of ‘hypervisor’ technology was introduced that established x86 servers as the dominant means of coordinating virtual traffic. This new approach removed issues surrounding the misinterpretation of server-client commands that had previously led to server failure.
Using well known x86 server hardware, the new VMware made it possible for ‘host’ machines to partition storage into ‘guest’ storage capable of running operating systems and applications, thus creating a server within a server.
Modern Applications - Types of Virtualisation
Your business venture could benefit from virtualisation in many ways. The main applications for Virtualisation in a modern workplace include:
- Memory Virtualisation
RAM is released from performing tasks for a single network and may process requests for data sent by any client device connected to any guest network positioned within the host cluster.
- Database Virtualisation
Data may be ‘pooled’ in the database layer of your computer network (i.e. across servers), allowing permitted access to files from client devices connected to different servers.
- Network Virtualisation
Partitioned storage is set up with the intention of combining elements of other networks with the aim of creating a new and purpose designed internal network the emulates physical hardware.
