RDS 支援 Storage Auto Scaling

Amazon RDS 推出了 Storage Auto Scaling:「Amazon RDS now supports Storage Auto Scaling」。

看起來傳統 RDBMS 類的都支援 (也就是非 Aurora 的這些):

Starting today, Amazon RDS for MariaDB, Amazon RDS for MySQL, Amazon RDS for PostgreSQL, Amazon RDS for SQL Server and Amazon RDS for Oracle support RDS Storage Auto Scaling.

仔細看了一下新聞稿,裡面都只有提到 scale up,沒有提到 scale down,這個功能應該是只會提昇不會下降,所以要注意突然用很多空間,再砍掉後的問題:

RDS Storage Auto Scaling automatically scales storage capacity in response to growing database workloads, with zero downtime.

RDS Storage Auto Scaling continuously monitors actual storage consumption, and scales capacity up automatically when actual utilization approaches provisioned storage capacity.

除了香港外的所有商業區域都提供:

RDS Storage Auto Scaling is available in all commercial AWS regions except in Asia Pacific (Hong Kong) and AWS GovCloud.
