[R-sig-hpc] R on Amazon Web Service question

[Takatsugu Kobayashi]

Hi

I am a newbie to R/AWS and please forgive me my basic question. I
placed this thread in AWS Forum but haven't heard from the community
yet.

I was told by my boss at my company to set up the system in which to
process a large dataset and analyze it statistically. The input data
ranges from 5GB - 10GB.

The packages of AWS products I can think of inclues

- EC2 high memory instance for data processing
- RDS Oracle DB for data processing

and

- EC2 medium-large CPU instances for data analysis with R
- Map Reduce for data analysis with R

 and

- S3

Now I have two questions regarding R and AWS:

1. Is ONE medium-high CPU instance enough for statistical-analysis of
that large dataset/
2. Should I subscribe the same number of MapReduce services as those
of EC2 instances?

Thanks in Advance.

Taka
