The alternative that is offered by default when Workload Planning returns that an existing cluster does not have the capacity to accommodate the selected virtual machines is cost comparisons for running in hybrid/private/public cloud. Workload Planning is a feature ofvRealize Operations that allows the administrator to plan and optimize the workload placement and capacity of the vSphere resources in the environment1. Workload Planning can be performed using two scenarios: Workload Optimization and What-If Analysis. Workload Optimization is a scenario that automatically balances the workload across the clusters and datastores based on the business and operational intents, such as performance, consolidation, or compliance2. What-If Analysis is a scenario that simulates the impact of adding or removing workloads, hosts, or datastores, or changing the demand or configuration of the existing workloads3. When Workload Planning is performed using the What-If Analysis scenario, and it returns that an existing cluster does not have the capacity to accommodate the selected virtual machines, the alternative that is offered by default is cost comparisons for running in hybrid/private/public cloud. This alternative allows the administrator to compare the estimated costs of running the selected virtual machines in different cloud platforms, such as VMware Cloud on AWS, Microsoft Azure, or Amazon Web Services, and to choose the best option for the business needs and budget4. Cost options for increasing cluster capacity with additional hosts (option B) is not the alternative that is offered by default, but it is another option that can be selected by the administrator. This option allows the administrator to estimate the costs of adding new hosts to the existing cluster, and to choose the best host model and quantity for the capacity and performance requirements5. Modifications to virtual machine configuration (option C) and modifications to host configurations (option D) are not alternatives that are offered by Workload Planning, as they are not related to the workload placement and capacity planning. These modifications can be performed using other features of vRealize Operations, such as Reclaimable Waste, Oversized Virtual Machines, or Configuration and Compliance. References:

vRealize Operations provides the following three key benefits within an environment:

• Capacity optimization: vRealize Operations helps you optimize the capacity of your infrastructure and applications by providing visibility, analysis, planning, and automation. You can monitor and forecast the demand, supply, and utilization of resources, identify and reclaim unused or overprovisioned resources, balance the workload across clusters and datastores, and plan for future growth or consolidation scenarios. You can also automate the capacity optimization actions based on policies and alerts.
• Performance optimization: vRealize Operations helps you optimize the performance of your infrastructure and applications by providing real-time and historical metrics, alerts, dashboards, and reports. You can monitor and troubleshoot the health, risk, and efficiency of your environment, identify and resolve performance issues, analyze the root cause and impact of problems, and optimize the configuration and placement of your workloads. You can also automate the performance optimization actions based on policies and alerts.
• Monitoring and troubleshooting: vRealize Operations helps you monitor and troubleshoot your environment by providing comprehensive and integrated visibility across physical, virtual, and cloud infrastructures. You can collect and analyze data from various sources, such as vSphere, NSX, vSAN, Kubernetes, AWS, Azure, etc., and correlate them to provide a unified view of your environment. You can also leverage artificial intelligence and machine learning to detect anomalies, generate smart alerts, and provide recommendations. You can also use various tools, such as dashboards, heat maps, topology maps, logs, etc., to drill down into the details and resolve issues faster.

To enable east/west firewall in VMware Cloud Director Tenant Portal, you need to perform the following steps:

• Login to Customer Organization and go to Networking Section of Tenant Portal. This is where you can access the networking capabilities provided by NSX Data Center for vSphere in your VMware Cloud Director organization virtual data center.
• Go to Edge Gateways and enable firewall on one of the Edge Gateways. This will allow you to configure the edge gateway firewall rules for north/south traffic enforcement and perimeter security functionality. You can also enable other services such as NAT, VPN, load balancing, etc. on the edge gateway.
• Go to Networking and enable Distributed Firewall for one of the Network inside the Network section. This will allow you to configure the distributed firewall rules for east/west traffic isolation and access control. You can also apply security policies and groups to the network and the virtual machines within it.
