AWS'EMR与EC2定价混淆

来源:互联网 

https://aws.amazon.com/emr/pricing/ Can someone explain why the price for EMR and EC2 differs so much, we are considering whether build our spark cluster on EMR or using Clourdera on EC2. Did I miss anything obvious? Thanks

https://aws.amazon.com/emr/pricing/有人可以解释为什么EMR和EC2的价格差别如此之大,我们正在考虑是否在EMR上构建我们的火花簇或在EC2上使用Clourdera。我错过了什么明显的事吗?谢谢

What is EMR?

什么是EMR?

Amazon EMR provides a managed Hadoop framework that makes it easy, fast, and cost-effective to process vast amounts of data across dynamically scalable Amazon EC2 instances.

Amazon EMR提供了一个托管的Hadoop框架,可以轻松,快速且经济高效地跨动态可扩展的Amazon EC2实例处理大量数据。

What is EC2?

什么是EC2?

Amazon EC2’s simple web service interface allows you to obtain and configure capacity with minimal friction. It provides you with complete control of your computing resources and lets you run on Amazon’s proven computing environment.

Amazon EC2的简单Web服务界面允许您以最小的摩擦获取和配置容量。它为您提供对计算资源的完全控制,并允许您在亚马逊经过验证的计算环境中运行。

Now, what is EMR pricing?

现在,什么是EMR定价?

EMR pricing is essentially the price you pay for "Cluster Management" related computing.

EMR定价基本上是您为“群集管理”相关计算支付的价格。

In a big data setup, cluster computing is not enough, you need "node computing" too, that is where EC2 and it's pricing comes into picture.

在大数据设置中,集群计算是不够的,您也需要“节点计算”,这就是EC2及其定价的结果。

As explained in EMR Pricing documentation, you will be charged for both EMR computing & EC2 computing when you use EMR.

如EMR定价文档中所述,使用EMR时,您将需要支付EMR计算和EC2计算费用。

The Amazon EMR price is in addition to the Amazon EC2 price (the price for the underlying servers). There are a variety of Amazon EC2 pricing options you can choose from, including On-Demand (shown below), 1 year & 3 year Reserved Instances, and Spot instances.

Amazon EMR价格是Amazon EC2价格(底层服务器的价格)的补充。您可以选择各种Amazon EC2定价选项,包括按需(如下所示),1年和3年预留实例以及竞价型实例。

Why the pricing different?

为什么价格不同?

It depends on what type of service & hardware being used and ultimately only AWS team can answer.

这取决于所使用的服务和硬件类型,最终只有AWS团队才能回答。
