Although the rewards of implementing a virtual network are widely understood, potential pitfalls lie in wait for the unwary.
Virtual environments have unique challenges and requirements that are not present in traditional physical environments, and trying to manage a virtual environment like a physical one creates problems. When a server becomes a virtual machine (VM), it shouldn’t be managed like a physical server since the guest operating system on a physical server has direct and exclusive access to the physical server hardware. In virtualisation, a VM has virtual hardware that is emulated by a hypervisor that controls access to the underlying physical hardware.
Virtualisation is a layer inserted in between the hardware and the guest operating system. This is all transparent to the guest operating system, which is unaware that it does not have exclusive access to the hardware.
There are five key areas that a specialist virtualisation management solution should cover to ensure the effective management of a virtual environment. Addressing these will eliminate any potential threats that may disrupt or impact the proper operation of VMs. These key areas are:
