Cassandra 也被 AWS 包成服務了

也是剛剛發表的服務 (所以在 Twitter 上看到),把 Apache Cassandra 包成服務,叫做 Amazon Managed Apache Cassandra Service:「New – Amazon Managed Apache Cassandra Service (MCS)」。

而且是個 serverless 服務,直接用服務,不需要管理機器:

Amazon MCS is serverless, so you pay for only the resources you use and the service automatically scales tables up and down in response to application traffic.

從計費的方式也可以看出來這點,是對 Write request units、Read request units 與 Storage 收費,沒有看到機器的費用。

不過稍微算了一下不算便宜,如果沒有用到 Cassandra 的特性的話,比 DynamoDB 貴一些?

目前是 open preview 狀態,是個可以用但是不掛保證的意思:

Amazon MCS is available today in open preview in US East (N. Virginia), US East (Ohio), Europe (Stockholm), Asia Pacific (Singapore), Asia Pacific (Tokyo).
