Moving to a virtualized architecture will have the greatest impact on vendor management, as it will require the enterprise to select, contract, and monitor the performance of the cloud or virtualization service providers. Vendor management is essential for ensuring that the virtualized architecture meets the enterprise’s requirements, standards, and expectations, as well as for managing the risks, costs, and benefits of the virtualization strategy. Vendor management also involves negotiating and enforcing service level agreements (SLAs), ensuring compliance with regulations and policies, and resolving any issues or disputes that may arise with the vendors.
System life cycle management, asset classification, and vulnerability management are also important aspects of IT governance, but they are not as significantly affected by moving to a virtualized architecture as vendor management. System life cycle management is the process of planning, developing, testing, deploying, maintaining, and retiring IT systems. Asset classification is the process of identifying, categorizing, and labeling IT assets based on their value, sensitivity, and criticality. Vulnerability management is the process of identifying, assessing, prioritizing, and mitigating IT vulnerabilities that may pose a threat to the enterprise’s security or operations. These processes may need to be adapted or updated to accommodate the virtualized architecture, but they are not fundamentally changed by it.
