To ensure a highly available shopping cart application, three key cloud management design decisions should be made: First, create a vRealize Orchestrator workflow to remediate any CPU issues automatically to maintain optimal performance. Second, configure vRealize Operations to trigger this workflow in response to specific alerts, ensuring timely and automated handling of issues. Third, set up a vRealize Operations alert that is activated when the application's CPU usage exceeds a certain threshold, facilitating proactive management of resources. These actions combined will help maintain high availability and an optimal shopping experience.
