3. IaaS Cloud Infrastructure-as-a-Service (IaaS)
storage space, software and network equipment are offered to customer as pay per use.
Customer can deploy their own software.
Amazon EC2, GoGrid , 3 Tea, FutureGrid and the Rackspace Cloud provide IaaS service

4. Nimbus on FutureGrid
Nimbus is an open source to run virtual machines on FutureGrid hardware.
You can upload your own Virtual Machine image.
Each Virtual machine is assigned a public address.
User can login as root via SSH to run services, configure the system and perform computations.

5. Nimbus Architecture

6. Application – Reporting Tool
Reporting Application is developed in Shell scripting.
Input – CSV format.
Validation of data using awk scripting.
Final result – HTML format.

7. Nimbus Cloud - Access Project Lead Project Member
Once the project you participate in is approved
Apply for an HPC & Nimbus account
You will need an ssh key
Create a Portal account
Create a project
Add project Members
Create a portal account
Ask your project lead to add you to the project

8. SSH Key Pair Generate the SSH key pair
Upload the public key into the HPC account
Account -> Portal Account -> Edit my ssh keys -> Add a public key
Insert a title (such as, keyForFutureGrid)
Paste the public portion of your key (that is, the content of id_rsa.pub file)

9. Nimbus Client Download
Download nimbus client from
Connect to hotel on FutureGrid using username and SSH public key.
Eg: $ ssh
Unpack the nimbus client into the future grid systems
Eg: $ tar xzf nimbus-cloud-client-020.tar.gz 
Check if everything is ok
Eg: $ bin/cloud-client.sh --help

10. Using Nimbus Client List the available image in the system
$ ./bin/cloud-client.sh --list
 Run the "hello-cloud' image
$ ./bin/cloud-client.sh --run --name hello- cloud --hours Hostname: vm-156.uc.futuregrid.org ...
 "vm-013" reached target state: Running
Log into the VM
$ ssh

11. Using Nimbus Client Querying workspace
check the status for all instances
        $ ./bin/cloud-client.sh --status   
check the status for one instance       
        $ ./bin/cloud-client.sh --status-handle <vm_id>
Saving workspace changes
$ ./bin/cloud-client.sh --save --handle <vm_id>
--newname <customName>

12. Using Nimbus Client Adding Image to Nimbus Client
$ bin/cloud-client.sh --transfer --sourcefile <name>
Check if your workspace has been created
$ ./bin/cloud-client.sh --list
Deleting workspace
  $ ./bin/cloud-client.sh --delete --name <name>
Terminate a workspace $ ./bin/cloud-client.sh --terminate --handle <vm_id>

13. Application Deployment
Instead of copying the application. OS image is generated.
apt-get install qemu
create [-f fmt] [-o options] filename [size]
It is uploaded into FuturGrid Hardware.
Image then in added into the Nimbus Client.
Application can be accessed from the Virtual machines.
Users can access the application from web if they have the public key and phrase key.
