ApsaraDB for Redis supports Pay-As-You-Go instances. The following describes how to buy a Pay-As-You-Go instance.
Prerequisites
Before activating ApsaraDB for Redis, you need to have at least one ECS instance. For details about how to buy an ECS instance, refer to Buy an ECS instance.
Procedure
Go to ApsaraDB for Redis homepage, and click Buy Now. Or you can log on to Redis Console and click Create Instance in the upper-right corner.
Choose Region, Zone, Instance Type, Network Type, and Quantity, and set the Logon Password and Instance Name.
Note:
Through configuration change, a master-slave instance can become a cluster instance which has functions different to those of the master-slave instance. For details, refer to Commands supported by ApsaraDB for Redis.
ApsaraDB for Redis can be accessed only through the intranet. It is recommended that you configure ApsaraDB for Redis instance and the ECS instance in the same zone of the same region.
Click Buy Now to go to the Confirm Order page. Read and accept the Terms of Service for ApsaraDB for Redis, check the order information, and click Pay Now to make the payment.
Select a payment method on the payment page and click the Confirm button. After the payment is made, a message that reads “Payment Successful” will be displayed. After one to five minutes you can log on to the console to view the instance bought.
Note: ApsaraDB for Redis is consistent with Redis in terms of product behavior. When a new instance is created, it generates database metadata which occupies a fraction of the instance’s storage space. The occupied space is shown on the ApsaraDB for Redis Console.
For master-slave instances, the generated database metadata occupies a space of about 32 MB.
For cluster instances, the generated database metadata occupies a space of about 32 MB multiplied by the number of nodes.
