  1. Types of Cloud computing

   
与事先的区分是AWS初叶认同IaaS/PaaS/SaaS的分歧,同时对Cloud/Hybrid/On-premises
做了介绍,不再只强调Cloud的贰个词了。

  1. Global Infrastructure

     2018.1.31日, AWS 云在举世 18 个地理区域内运转着 五十个可用区,并颁发表署充实巴林、中国香江特别行政区、瑞典王国和米国第三个 AWS

Dedicated instances定价

https://aws.amazon.com/cn/blogs/aws/amazon-ec2-dedicated-instances/

Pricing
      When you launch a Dedicated Instance, we can’t use the remaining
“slots” on the hardware to run instances for other AWS users. Therefore,
we incur an opportunity cost when you launch a single Dedicated
Instance. Put another way, if you run one Dedicated Instance on a
machine that can support 10 instances, 9/10ths of the potential revenue
from that machine is lost to us.

      In order to keep things simple (and to keep you from wasting your
time trying to figure out how many instances can run on a single piece
of hardware), we add a $10/hour charge whenever you have at least one
Dedicated Instance running in a Region. When figured as a per-instance
cost, this charge will asymptotically approach $0 (per instance) for
customers that run hundreds or thousands of instances in a Region.

那篇Blog是贰零壹叁年的,未来定价为运转dedicated实例 2$/hour.
