Note: To make the placement group effective you need to add more than one instance. You can add additional instances to this placement group later but its recommended by AWS to launch all the instance at once to avoid any capacity issue in the future. You can customize the instance’s configuration but in this demo, we are focusing on placing instances using the placement group. Hence we are skipping additional instance configurations.

Step 8: Review the instance configuration and click ‘Launch’

Step 9: Select Key Pair and click ‘Launch Instances’
