Instrumenting the Virtualised Datacentre … for Performance SLA’s - On the path to a single view of infrastructure performance across the enterprise

This document is addressed to Infrastructure Managers (looking after mission-critical applications) responsible for monitoring SLAs (Service Level Agreements) for virtualised infrastructure; their staff; and (probably executive summary only) associated business managers.
The business issue we spotlight in this document is that performance affects infrastructure risk just as much as availability, but vendors of virtualised infrastructure platforms and services are loath to provide effective performance SLAs. In fact, even if they do provide performance information, can it be relied on to be unbiased? In the increasingly virtualised world, in order to deliver services reliably, companies need seamless access to performance metrics across their entire infrastructure, whether on-premises or in private/ hybrid/public cloud.
