Hi all,
things are moving and I am more and more interested in the Amazon computer
cloud.
For the moment I just tested launching and logging in instances, and it is
really easy. Here is a debianised digest from a blog I read:
( http://paulstamatiou.com/2008/04/05/how-to-getting-started-with-amazon-ec2 )
- Create a EC2 accound (gives a S3 account automagically).
http://aws-portal.amazon.com/gp/aws/developer/subscription/index.html?productCode=AmazonEC2
- Install some non-free software from Amazon (Russel Coker has preliminary
source packages for it.)
http://etbe.coker.com.au/2008/10/04/getting-started-with-amazon-ec2/
- Setup environoment variables:
EC2_HOME (did not understand the purpose yet).
EC2_PRIVATE_KEY EC2_CERT points at the key and certificate downloaded at
account creation.
- Create a SSH key:
ec2-add-keypair keyname(arbitrary) > filename(I put it in .ssh)
(optional:) chmod 600 your new key, and set a passphrase with `ssh-keygen -f path/to/sshkey -p'.
- Launch/use/stop instance:
ec2-run-instances ami-number(a unique image ID) -k path/to/sshkey
Get essential parameters from your runnign instance: ec2-describe-instances
Open ssh port: ec2-authorize default -p 22
ssh -i path/to/sshkey root@name.got.by.ec2-describe-instances
ec2-terminate-instances instance-number (also obtained with ec2-describe-instances).
Some people apparently aim at being comprehensive with Ubuntu and Debian
images: http://alestic.com/
I will try to build my own image for the moment. In the mid-term, I think that
it would be great to provide 100% Debian Med images for genomics (probably with
no GUI programs). I will also investigate how easy it is to share data on the
Amazone S3 storage system. Steffen's getData could be strenghtened and enhanced
to produce many indexes for the programs we ship (like emboss, NCBI blast,…),
and if we package it, the image and data couples can stay 100 % Debian.
Unless there is a Free alternative that I overlooked, would there be
people interested in preparing semi-official Debian Med images ?
Have a nice day,
