The system allows user to select installation packages, operating system (OS) customizations, and image compliance with the intended host machine's laaS standards.

[0022] FIG. 2 illustrates a schematic diagram of a system for creating an

Infrastructure as a Service (laaS) image in accordance with one embodiment of the present invention. The system involves generally an laaS user 202, an laaS 204 deployed on a remote host machine, and an laaS image creation system. In one implementation, the present invention can be a dedicated service serving as a intermediate agent remotely located from the user who wish to deploy the IaaS's image and the IaaS's host for hosting the IaaS's image once deployed. It is of course understood that the implementation can also be a integrated feature available at the laaS host for creating the laaS image. Briefly, the laaS user 202, also referred herein as "the user" for simplicity, submits a new laaS image request to the laaS image creation system 206 to deploying on the laaS 204. The laaS image Creation system 206 provides user a bundling system that bundles user selected operating system (OS) and applications to be resided in the new image. User does not need to interact with the hypervisor of the host machine or package repository because the laaS image creation system will be taken over the responsibility on the user behalf based on the selected configurations automatically. [0023] FIG. 3 illustrates an IaaS creation system 300 in accordance with one embodiment of the present invention. The IaaS image creation system 3O0 comprises an user interface (UI) module 302, a virtual machine (VM) creation module 304, a bundling database module 306, a repository module 308 and a bundling module 310. As depicted, an IaaS user, or simply user, is required to register with a user account with the IaaS image creation system 300 and logon to the system 300 to submit a new customized image request through the system 300. The IaaS image creation system 300 provides the UI module 302 to serve as a user interface for creating the image and monitoring its creation progress. The UI facilitates a platform for user to perform all the customizations on the IaaS image creation system 300 at ease. All the user's selections and customizations are stored on the bundling database module 306 as bundling information. The bundling information is accessible by the VM creator module 304 to create the requested image.

[0024] The VM machine creator module 304 serves as an engine to manage and monitor the entire image creation process. The VM creator module 304 actively checks for new image creation request available from the bundling database module 306. Once the new image creation request is available, the VM creator module 304 retrieves the requested guest OS and the application packages from the repository module 308. The repository module 308 is provided for storing different guest OS and application packages therein.

[0025] Once the requested OS and application packages are retrieved, the VM creator module 304 boots a VM locally for preparing the retrieved OS and application packages based on the user's request from the bundling database module 306 to form a new VM raw image. Once the VM raw image is ready, it is transfer to the bundling module 310 creates an image from the VM raw image that is in compliance with the IaaS for publishing over the computing cloud.

[0026] FIG. 4 illustrates a block diagram of the VM creator module 304 of the

FIG. 3 in accordance with one embodiment of the present invention. The VM creator 304 comprises a VM preparation module 402, a monitoring module 404, a service interval timer 406, a VM pool module 408, a repository client module 410, and a boot and DHCP module 412. The VM preparation module 402 is adapted for preparing a virtual machine accordingly to the user request. The VM preparation module 402 receives the request to create new VM through the monitoring module 404. During the VM preparation, the VM preparation module 402 creates a VM with configurations, such as memory sizes, processing power, network requirements, etc. as defined by the user in the request. The service interval time 406 assists the VM preparation module 404 to receive at a predetermined interval. The predetermined interval is available to coordinate the workload, which can avoid sudden spike of incoming requests that overload the system. Once the VM is created, it is being pushed to the VM pool module 408 for booting up the same. The VM pool module 408 to serve as the core engine for preparing VM based on the user request that defines the type of OS, selected packages and configurations, etc. It boots up the VM and assign and IP address to the VM through the Boot and DHCP module 412. Once the VM is booted up, the VM pool module 408 interfaces with the repository client module 410 for querying and retrieving the requested operating system and application packages from the repository module 308. The VM pool module 408 operationally updates the monitoring module 404 status of the image creation process, which can be outputted onto the UI. Once the VM is created with all the requested OS and application packages deployed, the VM pool module 408 transfer the VM in a raw image form to the bundling module 310 for publishing.

[0027] FIG. 5 illustrates a block diagram of the bundling module 310 of FIG. 3 in accordance with one embodiment of the present invention. The bundling module 310 comprises a bundling monitor 502, an image bundler 504, an image repository 506, a bundling queue 508 and a service interval time 510. The bundling module 310 is used for creating an IaaS compliance image from a VM raw image from VM creator module 304. The bundling monitor 502 is provided for monitoring and controlling the bundling traffic for the bundling module. The bundling monitor 502 creates the bundling queue 508 and update it as the bundling process goes on. It acquires the latest status of the bundling tasks and update the bundling information to the VM creator module 304 in order to arrange for the VM creator module 304 to upload VM raw image at a suitable timing. The VM raw image is stored at the image repository 506. The bundling monitor 502 also provides updates at a suitable time interval controlled by the service interval timer 510.

[0028] The image bundler 504 operationally retrieves the VM raw image from the image repository 506, preparing the same, uploading it, and register it as an IaaS compliance image at the cloud for publishing.

[0029] FIG. 6 illustrates a flow diagram of an overall process of an IaaS image creation in accordance with one embodiment of the present invention. The process includes receiving image creation request from the user through the UI at step 602 for storing on the bundling database, wherein the user requests include all the customization options; preparing a VM for the request through a VM creator module at step 604; once the VM is prepared, the requested OS and application packages are retrieved from the repository module for processing based on the request by the bundling module to create the IaaS image and the image is published to the IaaS at step 606; and monitoring the state and progress of the request through the bundling monitoring module and presents the state and progress it in a form that can be retrieved by the UI at step 608.

[0030] FIG. 7 illustrates a flow diagram of process carries out by the VM creator module 304 of FIG. 3 in accordance with one embodiment of the present invention. The process starts by having the service interval time triggers the VM module 304 to start at step 702. The VM creator module 304 generates a query to the bundling database (or bundling database module) 706 for new raw image creation request at step 704. If the request is determined to be an active request at step 708, the task state and progress of the active request is retrieved from the VM pool module 408 at step 712 and update the state and progress onto the bundling database 706, which ends the process until the service interval timer triggers again at the step 702 at the next time interval.

[0031] Returning to the step 708, if the request is not an active request, the VM creator module 304 checks if the request is a new request at step 722. If the request is not a new request, the process ends until the service interval timer triggers again at the step 702 at the next time interval where the earlier IaaS image creation has been successfully complete. If the request is determined to be a new request at step 722, a VM creation script is created at step 724. The script shall include the necessary commands for automating the image creation. A VM creation script, also referred herein as pre-script is exemplified below: [0032] pre- start script

[0033] # check i f Apache ' s binary is executable or fai l

[0034] [ -x /usr/ sbin/httpd ] [0035] # clear the /tmp directory from old s es sions

[0036] rm /tmp/ ses s_*

[0037] end script

[0038] Once the VM script is created, it is executed to create a new VM at step

726. The new VM will then be pushed to the VM pool module 408 at step 728. The boot and DHCP module 412 assigns an IP to the VM, and booting the VM components such as RAM disk and kernel, at step 732. The requested OS and application packages are then retrieved from the repository 736 at the step 734. As the VM is booted and launched, the OS and application packages are installed sequentially according to the image creation script at step 738. Once the installation is done, the VM will be shut down and the raw image will be copied to the image repository 744 at step 742.

[0039] FIG. 8 illustrates a flow chart of a bundling process in accordance with one embodiment of the present invention. The process starts having the service interval time triggers the bundling module 310 to start at step 802. Following that, bundling tasks are requested from the bundling queue 508 at step 804. Examples of the tasks may include changing the raw image format, changing disk offset, encrypting the disk and many others. Once the task is obtained, it is checked if it is an active task at step 808. If the task is an active task, the bundling monitoring module 502 retrieves the task state and progress to monitor its progress at step 812 and update the state and progress onto the bundling queue 508 at step 814, which ends the process until the service interval timer triggers again at the step 702 at the next time interval.

[0040] Returning to the step 808, when the task is determined as a non-active task, it is further determined if it is a new task at step 822. If the task is not a new task, the process ends until the service interval timer triggers again at the step 802 at the next time interval. If the task is determined to be a new task, the bundling module 310 gets the VM raw image from the image repository 506. An image creation script is then created at step 826 and executed at step 828. Once the image is created, it is published to the IaaS at step 832. For illustrations, not limitation, an image creation script is exemplified as follows:

[0041] unless (-e "$instancedir/disk" )

[0042] {

[0043] logger ("ERROR : $bundleid :

$instancedir/disk not found.");

[0044] system ("sed —in-place

's/failedFlag=0/failedFlag=l/' $BUNDLE_INI &");

[0045] system ("sed —in-place

's/ failedMsg=.*/failedMsg=Internal Error: Instance DISK file not found/' $BU DLE_INI &");

[0046] exit(l);

[0047] } [0048] $scpDISK=system ("$SCOPY $instancedir/disk

$REMOTE_BUNDLE_SERVER_USER\ @$RE OTE_BUNDLE_SERVER : /$REMOTE _BUNDLE_DIR/images/$bund1eid . img" ) ;

[0049] unless ($scpDISK == 0) {

[0050] system ("sed -

-in-place ' s/failedFlag=0/failedFlag=l/ ' $BUNDLE_INI &");

[0051] system ("sed -

-in-place ' s/AfailedMsg= . */failedMsg=Internal Error:

Failure in scp Instance IMG/' $BUNDLE_INI &");

[0052] logger ("ERROR

: $bundleid : Failure in scp Instance IMG: $scpDISK");

[0053] exit(l);

[0054] }

[0055] It is to be noted that the present invention facilitates a system for automating IaaS creation. As it was shown, the processes can be carried out automatically without the user further interventions after the user sends in the IaaS image creation request.

[0056] While specific embodiments have been described and illustrated, it is understood that many changes, modifications, variations, and combinations thereof could be made to the present invention without departing from the scope of the invention.
