Before using Cloud Shell, be aware of the following limitations.
Item | Description |
Number of VMs | Only one virtual machine (VM) can be created at a time regardless of the number of Cloud Shell sessions that are opened. All opened Cloud Shell sessions are automatically connected to the VM. |
Number of session windows | A maximum of five sessions can be opened at a time. |
VM destruction on no interaction | If no interactive operation is performed for 30 minutes or all sessions are closed, the VM is destroyed in 15 minutes. When you restart Cloud Shell, a new VM is created. |
VM destruction on expiration | A VM created by Cloud Shell is valid for only 1 hour. After the VM expires, Cloud Shell immediately destroys the VM. When you restart Cloud Shell, a new VM is created. |
File storage | Cloud Shell provides 10 GB of temporary storage. You can store your files in the /home/shell directory. However, the directory is reset when the VM is destroyed. You can choose to mount storage space for storage, which is automatically loaded each time Cloud Shell starts. |
Prohibition | Long-term use or computing and network-intensive malicious processes are not supported. In these cases, a session may be terminated or even prohibited without warning. |
