You must deploy a virtual machine scale set containing five instances as quickly as possible. Which approach should you use?

To deploy five instances quickly, a single virtual machine scale set (VMSS) is the most efficient method. The ScaleSetVM orchestration mode (also known as Uniform orchestration) is optimized for large-scale, identical instances, making it ideal for rapid deployment of many VMs from a single template. This mode ensures all instances are managed as a cohesive unit, simplifying deployment and management. Deploying five individual virtual machines and then modifying settings is significantly slower and more complex than using a VMSS. Changing Availability Zone settings or VM sizes after individual deployment adds unnecessary steps and overhead. While a VMSS with VM orchestration mode (Flexible orchestration) allows for more individual VM control, it's generally better suited for scenarios requiring diverse VM configurations or integration with existing VMs, not for the fastest deployment of identical instances.
