# Subscription
Users who have used cloud servers are very aware of the relationship between Image and Server:
- Image is a necessary component of cloud server, and it is the startup template of cloud server
- You must choose a Image when purchasing a cloud server
- To delete the A Image, you must install the B Image to replace it
Therefore, the purchase (subscription) of the image is equal to the process of deploying the image to the cloud server.
