Creating a Quickly-Provisioned BMS

Scenarios

When you create a common BMS (that is, a BMS booted from a local disk), its OS needs to be downloaded from the cloud and it also takes some time to install the OS. When you create a BMS that uses an EVS as its system disk, the OS has been installed on the disk and does not need to be downloaded or installed. In this way, the BMS can be provisioned within a short time when you apply for it.

A quickly-provisioned BMS has the following advantages:

• It is booted from an EVS disk and can be provisioned within about 5 minutes.
• CSBS backups ensure its data security.
• If it should ever crash, a BMS can be rebuilt to recover services quickly.
• Its image can be exported to apply its configurations to other BMSs, eliminating the need to repeatedly configure BMSs.

On the page for creating a BMS, select a flavor that supports quick BMS provisioning, set the system disk type and capacity, and configure other required parameters.

Procedure

You can create a BMS supporting quick provisioning by following the instructions in Creating a Custom BMS.

When creating the BMS, pay attention to the following:

• Flavor: Select physical.s4.medium, physical.s4.large, physical.s4.xlarge, physical.s4.2xlarge, or physical.s4.3xlarge. For more information about flavors, see Instance Family.
• Image: Not all public images can be used to create BMSs supporting quick provisioning.
• Disk: Set the system disk type and size.
• Auto Backup: You are advised to select Enable auto backup and set Backup Policy to ensure data security.
