For business scenarios in which web applications, mobile apps, logic processing applications, or small- or medium-sized websites are involved, we recommend that you use EHDD volumes, which are more cost-effective. For business scenarios in which medium- or large-sized databases, data analysis, data mining, or business intelligence is involved, we recommend that you use SSD volumes of EBS 3.0, which provide higher performance.
For more information about the common actions on EBS volumes, see User Guide
You can create an EBS volume in the EBS console or by calling the API. For more information, see Purchase EBS volumes.
No. After you purchase an EBS volume, you cannot change its availability zone. You must unsubscribe from or delete the EBS volume and then purchase a new one.
When you attach an EBS volume to a KEC instance, you can specify whether to release the EBS volume together with the KEC instance. You can enable or disable the feature of releasing an EBS volume together with a KEC instance by modifying the attributes of the EBS volume in the EBS console. You can also enable or disable the feature by calling the corresponding API.
Within seven days after a Subscription EBS volume expires, the EBS volume is frozen and cannot be used. During this period, the data in the EBS volume is retained. If you do not review the EBS volume within seven days, the EBS volume is released on the eighth day after expiration. Then, the data in the EBS volume is deleted and cannot be restored.
After the payment of a Pay-By-Daily-Config or Pay-As-You-Go (Monthly) EBS volume becomes overdue, the EBS volume is retained in the recycle bin for 2 hours. During this period, the data in the EBS volume is retained. If you do not renew the EBS volume within 2 hours, the EBS volume is released. Then, the data in the EBS volume is deleted and cannot be restored.
After a Pay-As-You-Go EBS volume is deleted, it is directly released and the data in it is deleted.
No. EBS 2.0 has been sold out and is about to be put out of service. It is not available for sale or scaling-out.
