① Select the type of elastic cloud server in the "Specifications" section. In this example, a universal computing type is chosen, which provides balanced computing, memory, and network resources and is suitable for most usage scenarios. Multiple specifications can be selected to avoid the risk of specified specifications being sold out during scaling activities.
② Select the appropriate image in the Image section. In this example, private images are chosen to facilitate users in creating images of existing elastic cloud servers that handle business. When scaling activities, private images are used to create elastic cloud servers, which can directly undertake business.
③ You can choose to encrypt the disk to enhance its data security. But if the image is not encrypted, the system disk is also not encrypted. ④ The login method can be either password or key pairing. In this example, the login method of username and password is selected.
