- You should be completely clear about what you are looking to achieve before implementing a virtualisation system as it may be a something that perhaps you don’t require. While this may sound obvious, the benefits are not always clear cut and generally, virtualisation tends to suit organisations that have more than 100 employees and more than 20 servers. The reason for this is that it might be uneconomic to set up a virtual system for a company with fewer servers.
- Virtualisation is a complex set of technology and will require a high level of service and support for it to be implemented effectively.
- Consultants will need to be used in order to carry out a migration plan.
- Unless the project is scoped out properly and by experts, it is not unheard of for companies to revert back to their previous system. This can be a costly exercise.
- It is a good idea to buy similar hardware from one manufacturer as they should all have the same specification and components.
- Training can potentially be a high overhead and should be considered when budgeting for the system.
- Virtualisation is aimed at reducing the amount of servers within an organisation. These systems will still need to be managed by an internal IT Department or by your supplier.
- Hardware investment. To gain maximum benefit from virtualisation, virtual machines should reside on computers with powerful processors. This may mean that you will need to purchase more powerful hardware which conversely will increase the required investment. The alternative is to continue using existing equipment which might not be as powerful and reduce the benefits of virtualisation.
