Managing Hybrid IT through Cloud Service Brokerage focuses on three key points: 1) Adopting cloud and hybrid IT models requires a new IT ecosystem and operational model to address issues like multiple providers, financial transactions, access and solutions. 2) Cloud service brokerage provides IT supply chain management by complementing current infrastructure, extending capabilities, and improving control through services like performance management and security monitoring across public and private clouds. 3) Cloud service brokerage supports the entire cloud IT lifecycle from planning and design to sourcing, deployment and governance, and helps drive operational excellence through cost optimization and reduced risk.
