Amazon RDS是否支持EBS以外的其他存储类型？
[英]Does Amazon RDS support other storage types than EBS?
问题描述
In the RDS FAQ it says, "Amazon RDS uses EBS volumes for database and log storage". 
在RDS常见问题中，它说：“ Amazon RDS使用EBS卷进行数据库和日志存储”。 Is there any way to get RDS to store its data on another kind of storage? 有什么方法可以让RDS将其数据存储在另一种存储上？ I'm asking because EBS has a reputation for being kind of slow. 我问是因为EBS以其速度慢而闻名。

It doesn't make much sense to use DB with ephemeral storage as losing your instance will mean losing your data. 将DB与临时存储一起使用没有太大意义，因为丢失实例将意味着丢失数据。 Therefore, using EBS with its better durability is preferred. 因此，最好使用具有更好耐久性的EBS。
You can use Provisioned IOPS for your EBS and with a combination of RAID0 on multiple EBS with P-IOPS on "EBS Optimized" instances you can get up to 10,000 IOPS which is rather enough for most DB applications. 您可以为您的EBS使用预配置IOPS，并结合使用多个EBS上的RAID0和“ EBS优化”实例上的P-IOPS，最多可以获得10,000 IOPS，对于大多数数据库应用程序来说已经足够了。 See more about Provisioned IOPS in RDS here: http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Overview.ProvisionedIOPS.html 在此处查看有关RDS中预配置IOPS的更多信息： http : //docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Overview.ProvisionedIOPS.html
