Hologres:Purchase a Hologres instance

Last Updated:Aug 30, 2023

Before you can use Hologres, you must purchase a Hologres instance. This topic describes how to purchase a Hologres instance by using an Alibaba Cloud account.


  • An Alibaba Cloud account is created.

  • Real-name verification is complete.

Background information

By default, the Alibaba Cloud account that is used to purchase an instance is a superuser of the instance. A superuser of an instance has all permissions on the instance.

A RAM user must be authorized by the Alibaba Cloud account before the RAM user can be used to purchase instances. For more information, see Grant permissions on Hologres to RAM users. A RAM user can follow the same procedure as an Alibaba Cloud account to purchase an instance.


  1. Go to the Hologres product page.

  2. Click Buy Now.

  3. Select a billing method and configure the parameters.

    A new Hologres instance occupies two IP addresses of a virtual private cloud (VPC). You must make sure that sufficient IP addresses in the vSwitch are available.

  4. Click Buy Now.

  5. On the Confirm Order page, verify the information about the instance that you want to purchase, such as the billing method, instance name, resources, and region. Read the terms of service and select the check box.

  6. Click Pay.

  7. Complete the payment on the Purchase page.

    After the instance is purchased, go to the Hologres console to view the instance information. For more information about how to use the Hologres console, see Overview.

    Hologres is compatible with PostgreSQL. You can connect to a Hologres instance from the PostgreSQL client for data analytics. You can also use extract, transform, and load (ETL) or business intelligence (BI) tools to connect to a Hologres instance.
