The cloudAlberto Scotto Thesis defense4 5. Our definition [sources: NIST, Gartner, IBM] Cloud computing is a computational model suchthat:o Services (in other words, computational resources) arerapidly provisioned on demand, through a local network orInternet;o The architecture is scalable and elastic, i.e. it is able tosustain varying workloads, as required;o It is self-managing: once the cloud has been properlyconfigured, it doesnt require human interaction.Alberto Scotto Thesis defense5 6.

Analysis Background: datacenter virtualized with VMwarevSphere 4.1 The issue: creating virtual servers takes too long (of theorder of weeks) Requirements: o Guest OSs : Windows 2008, RHEL 5 o Softwares: MySQL Server and MySQL Client o The estimate for the virtual servers to be created has to be visible to the user before he submits the form; it must be dynamic, such that it automatically refreshes everytime the user updates one of the parameters of the project Alberto Scotto Thesis defense14 14.

Provisioning MySQLImplementation (2) 1st step: configuring in TPM a simple sw product forMySQL Problem: as required by TSAM, cygwin is installed onWindows VMs, so DOS commands dont work Solution: forcing TPM to see Windows VMs as if theywere *nix VMs Implementation: extending the"Default_SoftwareInstallable_Install" workflow byexploiting the corresponding"Default_SoftwareInstallable_InstallPre" Extensionpoint LDO Alberto Scotto Thesis defense 18 18.

The estimateImplementation (2) The form for creating virtual servers is implementedby the Dojo class CreateProjectWithServer In this class we add custom functions whichcompute the estimate and refresh the HTML table To implement the dynamic estimate, we modify thedefault event handlers (e.g.: _onDiskChanged) sothat they also call our custom functions Decoupling between this class and the values ofthe rates of the resources (except for the prices ofthe licences of the OSs), realized thanks to AJAXcalls Alberto Scotto Thesis defense 21 21. Future work Estimate: decoupling should be also applied to theprices of the licenses of the OSs Creating reports for chargeback to implement utilitycomputing Alberto Scotto Thesis defense 22 22. Conclusions Cloud computing is an old idea with a promisingfuture (especially once standardized) In this presentation we have shown that it is possibleto build a private cloud solution with relative easethanks to the (documented) cutomizability of ISDM In a real-world context, things may be morecomplex, but everything is possible throughcustomization Alberto Scotto Thesis defense 23
