IBM is introducing a range of service which provide remote access to server computing resources and prices are based on use.
Virtual Server Services lets companies buy server computing power from IBM, and they then pay for what they use in the way utilities such as water and electricity are billed.
The servers in question are owned and managed by IBM and kept at the supplier's data centres. Computing power is delivered remotely to clients. After charging customers a one-time set up fee, IBM bills them according to use every month.
Customers can buy computing capacity on IBM's eServer xSeries machines based on Windows operating systems; eServer iSeries running OS/400; and eServer pSeries AIX-based Unix servers.
In July 2002 IBM had already introduced a similar service for IBM zSeries mainframes running Linux.
IBM also makes available on a similar on-demand basis network capacity and complementary managed server services, such as Internet connectivity, storage, backup and firewall.
