Apply the enterprise tagging strategy for asset management, cost tracking, and chargeback/showback using Azure Cost Management and Advisor. Monitor environments with Azure Monitor and enterprise tools such as Datadog, Splunk, and Dynatrace; integrate events, incidents, and changes with ServiceNow. Perform patching (Azure Update Manager), routine maintenance, capacity planning, and rightsizing; troubleshoot and resolve incidents as part of 24/7 operations support.
