Instance management

This topic introduces how to manage database instances in NebulaGraph Cloud, including suspending, resuming, scaling, and deleting instances.

Prerequisites

A database instance is created. For more information, see Create a database instance.

Suspend & resume an instance

To suspend an instance, click ... of an instance on the Database page or its details page. In the drop-down list, select Suspend and confirm this action in a pop-up window.

When the instance is suspended, note that:

  • Only the following costs will be charged:
    • Disk storage costs: $0.0002/GB/hour
    • Fixed costs for data transfer usage: $0.0225/hour (charged if access to the instance through a public or private network is enabled)
  • The instance is unaccessible, and read and write operations are impossible.
  • The instance metrics are not monitored.
  • The instance cannot be scaled.

To resume a suspended instance, click the Resume button for a database instance on the Database page. After confirming this action in a pop-up window, the instance's status will change from Suspended to Resuming, and then to Running. At this point, you will be charged fully based on your service plan and the affected items above will be restored.

Scale an instance

Note

  • To scale an instance, you must upgrade to a paid plan and the instance is in the Running status.
  • During scaling, the instance will be temporarily unaccessible.

When you first upgrade to a paid plan, the instance remains at 2 vCPUs, 4 GB of RAM, and 10 GB of storage. You can purchase a capacity bundle to reallocate the baseline resources.

After purchasing a capacity bundle, you can further scale your instance according to your workload requirements by using the following methods:

Purchase a capacity bundle

To purchase a capacity bundle, follow these steps:

  1. Click ... of an instance on the Database page or its details page.
  2. In the drop-down list, select Upgrade capacity.
  3. In the pop-up window, select a capacity bundle and click Upgrade capacity.

Resize node specification

To increase or decrease the vCPU and RAM resources for an instance, follow these steps:

  1. Click ... of an instance on the Database page or its details page.
  2. In the drop-down list, select Resize.
  3. In the pop-up window, select a node specification and click Resize.

Increase storage size

To increase the storage capacity for an instance, follow these steps:

  1. Click ... of an instance on the Database page or its details page.
  2. In the drop-down list, select Increase storage size.
  3. In the pop-up window, set the new storage capacity and click Increase storage size.

Note that after the storage size is increased, you are not allowed to change it within the following 6 hours due to the limitation of Amazon EBS.

Delete an instance

To delete an instance, click ... of an instance on the Database page or its details page. In the drop-down list, select Delete and confirm this action in a pop-up window.

For free trial users, your instance will be automatically deleted once the trial ends unless you upgrade to a paid plan beforehand.
