If you want to purchase Elastic Compute Service (ECS) instances that have the same configurations as an existing ECS instance, including the instance type, disk settings, image, and bandwidth settings and excluding the environment settings and data, you can use the Purchase Same Specifications feature in the ECS console to go to the instance buy page and quickly create ECS instances that are identical to the existing ECS instance. Alternatively, you can modify instance parameters on the instance buy page to create ECS instances that meet your business requirements.
