答案:D
1 GB存储在US-East-1:
(更新至2016年12月20日)
冰川:0.004美元/月(注:2016年大幅降价)
S3: 0.023美元/月
S3-IA(2015年9月公布):
$0.0125/月(+$0.01/gig检索费用)
EBS: $0.045-0.1/月(取决于速度- SSD与否)+ IOPS成本
EFS: 0.3美元/月
进一步的存储选项,可用于在处理数据时/之前临时存储数据:
SNS
SQS
运动流
DynamoDB, SimpleDB
以上成本仅为样本。不同地区之间可能存在差异,并且在任何时候都可能发生变化。此外,数据传输(到互联网上)还需要额外的费用。然而,它们显示了服务价格之间的比率。
这些服务之间有很多区别:
EFS 是:
Generally Available (out of preview), but may not yet be available in your region
Network filesystem (that means it may have bigger latency but it can be shared across several instances; even between regions)
It is expensive compared to EBS (~10x more) but it gives extra features.
It's a highly available service.
It's a managed service
You can attach the EFS storage to an EC2 Instance
Can be accessed by multiple EC2 instances simultaneously
Since 2016.dec.20 it's possible to attach your EFS storage directly to on-premise servers via Direct Connect. ()
EBS是:
A block storage (so you need to format it). This means you are able to choose which type of file system you want.
As it's a block storage, you can use Raid 1 (or 0 or 10) with multiple block storages
It is really fast
It is relatively cheap
With the new announcements from Amazon, you can store up to 16TB data per storage on SSD-s.
You can snapshot an EBS (while it's still running) for backup reasons
But it only exists in a particular region. Although you can migrate it to another region, you cannot just access it across regions (only if you share it via the EC2; but that means you have a file server)
You need an EC2 instance to attach it to
New feature (2017.Feb.15): You can now increase volume size, adjust performance, or change the volume type while the volume is in use. You can continue to use your application while the change takes effect.
S3是:
An object store (not a file system).
You can store files and "folders" but can't have locks, permissions etc like you would with a traditional file system
This means, by default you can't just mount S3 and use it as your webserver
But it's perfect for storing your images and videos for your website
Great for short term archiving (e.g. a few weeks). It's good for long term archiving too, but Glacier is more cost efficient.
Great for storing logs
You can access the data from every region (extra costs may apply)
Highly Available, Redundant. Basically data loss is not possible (99.999999999% durability, 99.9 uptime SLA)
Much cheaper than EBS.
You can serve the content directly to the internet, you can even have a full (static) website working direct from S3, without an EC2 instance
冰川是:
长期存档存储
储存非常便宜
回收可能非常昂贵
“回读”你的数据需要4个小时(所以只存储你知道你在很长一段时间内不需要检索的项目)
正如JDL的评论中提到的,在定价方面有几个有趣的方面。例如,Glacier、S3、EFS根据您的使用情况为您分配存储,而在EBS,您需要预先定义分配的存储。也就是说,你需要高估。(然而,向EBS卷添加更多存储是很容易的,这需要一些工程,这意味着您总是“多付”EBS存储,这使得它更加昂贵。)
