Conclusion: With the maturing of Server Virtualisation on industry standard (X86) and RISC/Unix servers, all IT organisations should evaluate its role in optimising IT infrastructure. See IBRS research note “Infrastructure Consolidation: Avoiding the vendor squeeze” October-05).
The recommend strategy is to start by using server virtualisation to enable the consolidation of non-production systems (i.e. dev/test/QA), progressing to consolidating smaller non-mission critical production applications and finally creating a virtual server infrastructure that simplifies and enables load-balancing, high-availability and disaster recovery. A well executed server virtualisation strategy will reduce complexity and increase agility, leading to better alignment of IT infrastructure with the applications requirements and business strategy.
