| Product Type |
Click Dedicated Cluster.
Note
- When you create an instance on one host that uses a local SSD or on multiple hosts
of which each uses a local SSD, you are not charged for the instance. This is because
the price of the host or the hosts includes the price of the instance.
- When you create an instance on one host that uses an enhanced SSD (ESSD) or on multiple
hosts of which each uses an ESSD, you must pay for the storage space allocated to
the instance. This is because you must pay only for compute resources when you purchase
the host that uses an ESSD or the hosts of which each uses an ESSD. A storage plan
supports the subscription billing method. You can use a storage plan to offset the
storage costs of pay-as-you-go instances deployed in the region where the storage
plan is purchased. We recommend that you use a storage plan to reduce your storage
costs.
|
| Region |
The region where you want to deploy the host or hosts. By default, the region that
you selected in Step 2 is used.
|
| Zone |
The zone where you want to deploy the host or hosts. We recommend that you create
hosts in different zones to improve availability.
|
| Database Engine |
The database engine that you want to select for the host or hosts. Click MySQL.
|
| Dedicated Cluster |
The dedicated cluster in which you want to create the host or hosts.
Note
- If no dedicated clusters that run the specified database engine are available in the
specified region,Dedicated Cluster Created by Default is selected by default. In this case, the system creates a dedicated cluster for
the host or hosts that you want to create.
|
| VPC |
The virtual private cloud (VPC) where the dedicated cluster is deployed.
Note
- If a manually created dedicated cluster is selected, the system selects the VPC where
the dedicated cluster is created.
- If Create a new exclusive cluster by default is selected, the following rules apply:
- If one or more VPCs exist in the specified region, you can select one of the VPCs.
- You can also select Create a proprietary network by default. This way, the system creates a VPC for the dedicated cluster.
|
| vSwitch |
The vSwitch to which the host is connected or the hosts are connected.
Note
- If a vSwitch created in the specified zone already exists in the specified VPC, the
system selects the vSwitch.
- If no vSwitch created in the specified zone exists in the specified VPC, you can log
on to the VPC console and create a vSwitch in the specified zone. The vSwitch must be located in the specified
VPC.
- If you select the dedicated cluster and VPC that are created by the system, the system
creates a vSwitch.
|
| Authorization |
If this is the first time that you create an ApsaraDB MyBase host, click Authorize Now. On the Cloud Resource Access Authorization page, click Confirm Authorization Policy in the lower-left corner of the page to grant permissions on security groups.
Notice After you grant permissions, the AliyunRDSDedicatedHostGroupRole role is displayed on the Roles page in the RAM console. If you want to use ApsaraDB MyBase dedicated clusters, retain this role. If this
role is deleted, you must grant the permissions again to perform related operations.
|
| Host Image |
The OS image type of the host or hosts. By default, AliLinux is used.
|
| Storage Type |
The storage type of the host or hosts. You can click Local SSD or Enhanced SSD (ESSD).
|
| Host Instance Type |
The specifications of the host or hosts. |
| Storage Capacity |
The storage capacity of the host or hosts. This parameter is displayed only when Storage
Type is set to Local SSD.
|
| Quantity |
The number of hosts that you want to create. For more information, see Number of hosts that are required to deploy an ApsaraDB MyBase for MySQL instance.
|
| Duration |
The subscription period of the host or hosts. You can select Auto-renewal to prevent the host from being released upon expiration. If you select Auto-renewal
and forget to renew the subscription to the host or hosts before the subscription
period elapses, the system renews the subscription to the host or hosts based on the
specified subscription period. For example, if you specify a subscription period of
three months, the system renews the subscription to the host or hosts at an interval
of three months.
