Conclusion: Infrastructure Consolidation has been a hot topic since the IT downturn in 2001/2. Unfortunately, this topic has been hijacked by IT vendors and used as justification for purchasing their latest high-end technology. To date most consolidation efforts have been technology projects with poorly defined goals that rarely go beyond implementing a specific technology. As a result most consolidation projects fail to deliver lasting benefits.
To ensure long term benefits, IT organisations (ITOs) must view infrastructure as an asset to be optimised for an appropriate mix of Total Cost of Ownership (TCO), agility and robustness as required by the business. The critical success factor is the recognition that complexity is the key driver of these characteristics and that a planning process (not technology) is necessary to reduce and control complexity.
