Google Cloud Platform 也開始玩 Reserved Instances 的想法了 (Committed use discounts)

看到 Google Cloud PlatformGoogle Cloud Engine 也開始提供 RI 的想法了:「Committed use discounts」。

本來就有 Sustained use discounts,當你用到一定的量時就會自動折扣,不需要人工介入,不過對於 7x24 開機的 instance 來說,能得到的折扣還是比不上 AWS 的 RI。

這次 Committed use discounts 折扣的方式跟 Amazon EC2 類似,一樣是一年與三年。計價方式不同的原因是因為 GCE 提供 custom type,使用者可以自己選 vCPU 與 Memory,所以折扣的方式也是圍繞在這兩個選擇上規劃。

不過小台機器是不提供折扣的,這點就不像 AWS 上所有種類的機器都可以買 RI:

You can only use committed use discounts for predefined machine types and custom machine types. Small machine types, such as f1-micro and g1-small, are not eligible for committed use discounts.

目前是 beta:

This is a Beta release of Committed Use Discounts. This feature is not covered by any SLA or deprecation policy and may be subject to backward-incompatible changes.

所以 Netflix 也往 Google Cloud Platform 嘗試了...

看到「Netflix Security Monkey on Google Cloud Platform」這則消息,看起來 Netflix 也往 Google Cloud Platform 在嘗試了。

Netflix Security Monkey 本來是對 AWS 分析,現在則是開始支援 GCP (雖然還在 beta):

Security Monkey monitors policy changes and alerts on insecure configurations in an AWS account. While Security Monkey’s main purpose is security, it also proves a useful tool for tracking down potential problems as it is essentially a change tracking system.
