Conclusion: A recent survey by Ideas International showed that 2/3rds of IT organisations use virtual servers, at least occasionally in their data centres, with 1/3rd using them at least frequently. While server virtualisation is commonly associated with server consolidation, and as a method of lowering hardware costs; early adaptors are using virtual servers to create an agile, utility-like infrastructure that is better aligned to the business’s needs.
Leading IT organisations use virtualised infrastructure, based on virtual x86 servers (generally VMware) and networked storage, to decouple workloads and data from the underlying hardware. This enables new infrastructure capabilities that better support the business’s availability and capacity requirements. Unlike the earlier, over-hyped promises of utility infrastructure, infrastructure virtualisation is a simple, practical technique that is delivering measurable business and IT benefits now.
