Billing

• To use CodeArts Deploy, subscribe to CodeArts first. CodeArts Deploy cannot be purchased separately.
• CodeArts Deploy is available for free.
• However, the resources (such as ECSs, EIPs, and traffic) used by the deployed applications and the services on which the applications depend are charged by the corresponding services.
• If your account is in arrears, you can still use CodeArts Deploy for free. However, if the resources (such as ECSs, EIPs, and traffic) in CodeArts Deploy are unavailable when the account is in arrears, the corresponding application deployment may fail.
