One European financial institution, planning a new virtualization programme this year as they look to shed costs, have been spinning wheels on getting a capacity management process implemented. If compared to others trodden the same path, this lack of up-front diligence will cost them time, handling rollbacks due to failing performance, and money as they overprovision excess capacity. Another similar institution reported 20% of all their virtualization program was subject to rollback, due to performance issues in production.
As performance issues begin to bite, panic mode sets in and organisations are forced into hasty remedial action, often requiring advanced monitoring and diagnostics in these complex environments. I was contacted recently by a tools provider targeting this market space - panic mode is very advantageous for them!
Sizing and capacity planning in any virtualization initiative is key to assuring success. Looking ahead and avoiding performance issues before they become reality is key to efficient IT operations. Aligning technology considerations and IT spend with business requirements is key to safeguarding efficiency, effective asset use and CIOs' jobs. Or, as they said in old English times before IT existed: "a stich in time, saves nine"
