Implementing a menu based application in FutureGrid Alwin

Overview IaaS Cloud Nimbus on FutureGrid Nimbus Architecture Application Reporting Tool Starting Nimbus Cloud Using Nimbus Client Application Deployment

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

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.

Nimbus Architecture

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

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

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)

Nimbus Client Download Download nimbus client from http://www.nimbusproject.org/downloads/ Connect to hotel on FutureGrid using username and SSH public key. Eg: $ ssh username@hotel.futuregrid.org 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

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 2 ... Hostname: vm-156.uc.futuregrid.org ...  "vm-013" reached target state: Running Log into the VM $ ssh root@vm-253.uc.futuregrid.org 

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>

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>

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.
