Virtualisation – a broad concept, it includes solutions such as:
- programmable virtual devices,
- virtual machines operating on virtualisation servers of other producers,
The virtualisation of IT infrastructure is now one of the key trends in the sector. The availability of diverse forms of virtualisation is a factor enforcing innovation in digital data protection, yet it may trigger the outset of the traditional hardware solutions.
A rich choice of virtualisation methods enables applying this technology in both small business, using SaaS solutions and corporations, for which the advantages of virtualisation reflect in their balance sheets. When calculating the return on investment in virtualisation, the following factors are considered:
- lower energy cost (and related advantages of reduction in greenhouse gases emission),
- lower capital expenditure due to more economic use of hardware
- making their useful life longer
- Virtualisation and consolidation offer some non-monetary advantages as well:
- high availability and fast access to calculating power or capacity if needed,
- lower administrative expenditure
- more efficient data recovery after a failure thanks to the virtualisation management tools.
Virtual solutions ensure advantages typical for devices, such as higher efficiency and increased security, due to an optimized and strengthened operating system and at the same time they ensure flexibility of implementation depending on the Client’s preferences. The flexibility is achieved thanks to ensuring two implementation options:
- program device , often referred to as ‘hardware installation’
- virtual device virtual device, operating in the environment of the virtual machine
- The possibility of selecting a technology offers a few important economic advantages and ensures the maximum use of the existing investment in servers, which in the current economic climate will be more and more important.
Device virtualisation contributes to an increased use of the existing servers, because it supports consolidation and standardisation of the data processing centre. It also enables:
- eliminating of not standard mono-function equipment
- avoiding complicated management of the stack of the operating system and applications, which is typical for software-based solutions
- decreasing capital investment
- making the IT infrastructure more environmentally friendly
- decreasing the cost of ongoing maintenance and implementation.
