Virtual machine - made cloud computing possible
Harvard class:http://cm.dce.harvard.edu/2010/01/13450/L07/seg1/index_FlashSingleHighBandwidth.html^{Image Removed}

VM types:

• Xen -free
• VMware - commercial, used by industry, full virtualization
• Parallels - tailored for Mac users

Private cloud computing: http://aws.amazon.com/^{Image Removed}

And this is my 1st VM on the claud

...

1. On the left, go to 'Security Groups'
2. select 'default' fire wall (unless you have sth else already)
3. add & save : SSH tcp 22 22 0.0.0.0
4. now try ssh again

...

Mounting EBS (permanent) volume to the instance (it was not reliable for me, between sessions data were partially corrupted)

1. 1st time it need formating
   1. Browser: Create volume , using 'Volumes', pick 300GB (it is small and not pricy)
   2. Browser: right click on the volume, attache it to running Instance of VM, remember name, e.g.: /dev/sdf
2. ssh to VM
   1. partition this disk , e.g. using fdisk
      • fdisk /dev/sdf
        n : new partition
        p : primary
        1 : partion #1
        1 : (default begin)
        enter : (default end)
        p : print
        w : write partition
   2. format disk using mkfs
      mkfs.ext3 /dev/sdf1 ('1' is partition selected earlier)
      agrre on any question by pressing 'enter'
   3. mount disk as home dir named storage
      mkdir /storage
      mount /dev/sdf1 /storage
      cd /storage
      ls

      SCP file from AMI to local machine

scp -i ~/janAmazonKey.pem root@ec2-174-129-63-11.compute-1.amazonaws.com:"/bla_lis" .

You are done. Well, you need to pay for it. This is my 1st bill:

Bundling

...

& registering AMI

It works the best in a machine w/ installed Java and some EC2 software. This is reasonable instruction:http://www.linuxconfig.org/Howto_CREATE_BUNDLE_UPLOAD_and_ACCESS_custom_Debian_AMI_using_ubuntu
It is written for Ubuntu 9.04 machine, so I selected this VM:
ami-2bfd1d42 binarymillenium/ec2/ubuntu/version2/image.manifest.xml
and added the following:

next I added:
mkdir ~/aws
cd ~/aws
wget http://s3.amazonaws.com/ec2-downloads/ec2-api-tools.zip
wget http://s3.amazonaws.com/ec2-downloads/ec2-ami-tools.zip
sudo unzip -d /opt/ ec2-api-tools.zip
sudo unzip -d /opt/ ec2-ami-tools.zip

export EC2_HOME=/opt/ec2-api-tools-1.3-42584/

export PATH=$PATH:$EC2_HOME//bin/

export JAVA_HOME=/usr/

If c-shell is used do:

setenv EC2_HOME /opt/ec2-api-tools-1.3-46266/
setenv PATH $PATH":$EC2_HOME/bin/"

Now I was able to test the following command does sth
ec2-register

I probably should also have set
export EC2_PRIVATE_KEY=~/.ec2/pk-K5AHLDNT3ZI28UIE6Q7CC3YZ4LIZ54K7.pem
export EC2_CERT=~/.ec2/cert-K5AHLDNYYZI2FUIE6R7CC3YJ4LIZ54K7.pem
export EC2_ACCNO=155678941235
export ACCESS_KEY=1WQ6FJKYHJMPTJ3QR6G2
export SECRET_KEY=VDYxRzosnDWvxrJ97QntVpsSUBAavGHE1QJELEyY

If 'ruby' is missing execute:
sudo apt-get install ruby

Alternative:
sudo apt-get install ec2-ami-tools

Below are steps leading to bundling & registering

1. copy X.509 certificate
   scp -i ~/janAmazonKeyXXXXAmazonKey.pem ~/pk-KL6G2VUC25RUKKMKXUPTKRHHPAAM5Z3CXXXXXXXX.pem ~/cert-KL6G2VUC25RUKKMKXUPTKRHHPAAM5Z3CYYYYYYC.pem root@ec2-174-129-63-11.compute-1.amazonaws.com:"/mnt/"
   
2. bundle external image
   ec2-bundle-vol -d /mnt -k /mnt/pk-KL6G2VUC25RUKKMKXUPTKRHHPAAM5Z3CXXXXXXXX.pem -c /mnt/certKL6G2VUC25RUKKMKXUPTKRHHPAAM5Z3Ccert-YYYYYYYYY.pem -u AKIAJATKPFP7TANBRIAA nnnn-mmmm-kkkk -r i386 -p star-sl08b-image -v /bla_image --generate-fstab

1. Uploading the AMI to Amazon S3
   ec2-upload-bundle -b <your-s3-bucket> -m /mnt/sampleimage.manifest.xml -a <aws-access-key-id> -s <aws-secret-access-key>

1. Register Image at EC2
   ec2-register star-sl08b-s3-bucket/star-sl08b-image.manifest.xml
