SYNCHRONIZING A CLOUD SERVICE TEMPLATE WITH AN INFRASTRUCTURE TEMPLATE
BACKGROUND
[0001] Cloud computing is a delivery model for technology-enabled services that provides on-demand access to an elastic pool of shared computing assets. These assets include applications, servers, storage, and networks. The entire pool can be rapidly provisioned and scaled up or down as needed on a pay-per-use basis. In other words, these assets can be consumed "as a service." Cloud computing deployment models include private cloud; public cloud— in which provider-owned assets are shared, and service is provided on a pay-per-use basis to multiple entities; and hybrid cloud— which combines public cloud, private cloud, and traditional IT.

DETAILED DESCRIPTION OF THE INVENTION
[0006] Cloud computing service providers typically offer their services according to three formats: Infrastructure-as-a-Service (laaS), Platform-as-a- Service (PaaS) and Software-as-a-Service (SaaS).
[0007] In Infrastructure-as-a-Service (laaS) model, computing infrastructure is delivered as an outsourced service. An enterprise outsources the equipment used to support operations, including storage, hardware, servers and networking components to a cloud computing service provider, who in turn charges the user on the basis of "Pay as you go" model. Under laaS model, therefore, the users pay for only what they use.
[0008] Generally, upon receipt of a service request from a subscriber, a cloud service provider first gathers the subscribers' needs and then provisions the required computing resources (such as servers, networks, storage, applications, etc.) to the subscriber to fulfill the service request. The process of provisioning resources is mapped onto a service template for future use.
[0009] A typical service template defines the different resources that are required for a cloud service such as server, network, physical memory, and expandable storage. A service template may also include the provision to install applications as desired by a subscriber of the cloud service.
[0010] Once a service template is created, the cloud service provider identifies an infrastructure provider (or vendor) to provide a computing resource identified in the service template. For example, consider a service template for an infrastructure service that defines one or a plurality of server groups containing one or a plurality of servers with a minimum hardware specification. In this case, a
83598227 PATENT
_4- cloud service provider has an option of selecting any infrastructure provider who could provide the required servers with desired hardware specification. After an infrastructure provider has been selected, the selected infrastructure provider creates the resources as specified in the cloud service template and specifies the same in the form of an infrastructure template. Thereafter, the provisioned resources are deployed and offered as a service to a subscriber of the cloud service provider.
[0011] The infrastructure template created by an infrastructure provider thus becomes crucial to the success of a cloud service offering. But the infrastructure template can change at any time, and a cloud service provider may not be aware of it. If the template is changed without the knowledge of a cloud service provider, then what is made available to the subscriber may be different from what is claimed by a cloud service provider. This may go against the terms defined in a service- level agreement between a cloud service provider and a subscriber, and the cloud service provider may end up incurring losses. To provide an example, let's consider a service request to provision a cluster of database servers. Upon receipt of the service request, a cloud service provider creates a logical topology (service template) where it defines a database cluster and adds each provisioned database servers into it. The infrastructure provider then uses its infrastructure template to provision one or more servers. If the infrastructure template is changed to reduce the resources allocate to a server, then subsequent services requests that create the database cluster may not function properly due to insufficient resources. This could cause server unavailability, and go against of the terms of a service-level agreement.
[0012] Proposed is a solution for synchronizing a cloud service template with an infrastructure template. The proposed solution synchronizes a service template with changes in an infrastructure template thereby ensuring that the service
83598227 PATENT
-5- template is synchronized from the time the service template is completed till a request is submitted by a subscriber.
[0013] FIG. 1 illustrates a system 100 for synchronizing a cloud service template with an infrastructure template, according to an example. System 100 includes cloud service template 102, infrastructure template 106, and scheduler module 104.
[0014] Cloud service template 102 is akin to a building blue print designed by an architect before the start of a construction activity. Like a construction blue print, a typical service template aims to define various computing resources that are required for implementing a cloud service. These computing resources (also termed as service elements) may include, by way of non-limiting examples, server, network, physical memory, storage, applications, etc. In an implementation, a service template designer module may be used to create a cloud service template. A cloud architect (or service designer) of a cloud service provider may use a service template designer module to define various building blocks (computing resources) required for implementing a service in a cloud. These computing resources are used to create a cloud service template 102 for use by a subscriber, an administrator, an operator, etc. To provide an example, for a compute infrastructure service, various computing resources required to deploy the service such as number of CPU cores, amount of memory, size of boot disk, etc. are defined in the form of a service template offering. Once a cloud service template 102 is created, it can be used to deploy the corresponding service. A cloud service template 102 can also be reused or modified in future.
[0015] Infrastructure template 106 is similar to a cloud service template 102. In an implementation, an infrastructure template 106 (or infrastructure templates) is/are created by an infrastructure provider who may offer these templates to another entity such as a cloud service provider. Akin to a cloud service template
83598227 PATENT
-6-
102, a typical infrastructure template 106 aims to define various computing resources that may be required for implementing a cloud service. These computing resources may include, by way of non-limiting examples, server, network, physical memory, storage, applications, etc. A cloud service provider may use an infrastructure template 106 to design a service offering for a subscriber. Once a cloud service provide decides to use an infrastructure template 106 offered by an infrastructure provider, it may associate the infrastructure template 106 with its own cloud service template 102 for deploying a cloud service for a customer. In an implementation, an infrastructure template 106 may be created by a cloud service provider. Infrastructure template 106 may include a timestamp, for example, to indicate the day and/or time of its creation or modification.
[0016] Scheduler module 104 acts as an intermediary between cloud service template 102and infrastructure template. In an implementation, scheduler module 104 compares a timestamp of an infrastructure template 106associated with a cloud service template 102 with a timestamp of a latest version of the infrastructure template. In response to identifying a difference between the timestamp of the infrastructure template 106 associated with the cloud service template 102and the timestamp of the latest version of the infrastructure template, scheduler module 104 compares the computing resources represented in the cloud service template 102 with the computing resources represented in the latest version of the infrastructure template. And, in response to identifying a difference between computing resources represented in the cloud service template 102 with computing resources represented in the latest version of the infrastructure template, scheduler module 104 synchronizes the computing resources represented in the cloud service template 102 with the computing resources represented in the latest version of the infrastructure template. In an implementation, scheduler module 104 is created by a cloud service provider.

[0017] Components of system 100 i.e. service template, infrastructure template, and scheduler module are hosted on a cloud computing environment (or "cloud"). As used herein, the term "cloud" may include a public cloud, a private cloud, a hybrid cloud or a traditional data center offering cloud services. Cloud could offer, provide or deploy various types of cloud services for a user or customer. These could include Infrastructure as a Service (laaS), Platform as a Service (PaaS), Software as a Service (SaaS), and so forth. Cloud may include various types of service elements (or computing resources). These computing resources may be hardware resources, software resources, or any combinations thereof. For example, hardware resources may include computer systems, computer servers, workstations, or any other computer devices. And, software resources may include operating system software (machine executable instructions), firmware, and/or application software. Computing resources may also include virtual machines, virtual servers, storage resources, load balancers, firewalls, etc.
[0018] It would be appreciated that the components depicted in FIG. 1 are for the purpose of illustration only and the actual components (including their number) may vary depending on the computing architecture deployed for implementation of the present invention.
[0019] FIG. 2 illustrates a method of synchronizing a cloud service template with an infrastructure template, according to an example. At block 202, a timestamp of an infrastructure template 106 associated with a cloud service template is compared with a timestamp of a latest version of the infrastructure template. As mentioned earlier, a cloud service provider may use an infrastructure template 106(created by an infrastructure provider) to provision computing resources required for providing a cloud service to a customer. The cloud service provider links its cloud service template with the infrastructure template 106 to
83598227 PATENT
-8- provide the required cloud service. An infrastructure template 106 may include a timestamp denoting a date and/or time of its creation or last modification.
[0020] In an example, an infrastructure template provider (or infrastructure provider) may create, over a period of time, multiple versions of an infrastructure template each with its own distinct timestamp. To provide an illustration, let's consider a scenario wherein an infrastructure template comprising a cluster of five servers is created by an infrastructure provider. The infrastructure template is duly timestamped on the date of its creation. Subsequently, if a component associated with the infrastructure template is changed by the infrastructure provider, for instance, if the number of CPU cores or memory allocation associated with one of the servers in the template is modified, another version of the infrastructure template would get created with its own timestamp. Likewise, with subsequent changes, various versions of an infrastructure template may get created each having its own distinct timestamp. Thus, a latest version of an infrastructure template may be available with the infrastructure template provider.
[0021] A comparison between a timestamp of an infrastructure template associated with a cloud service template is compared with a timestamp of a latest version of the infrastructure template may be performed at various stages. For example, a comparison may be performed during creation of the cloud service template by a cloud service provider. In another example, a comparison may occur during publication of a cloud service template. In a yet another example, a comparison may take place during implementation of a service request based on the cloud service template.
[0022] At block 204, in response to identifying a difference between the timestamp of the infrastructure template associated with the cloud service template and the timestamp of the latest version of the infrastructure template, computing resources represented in the cloud service template are compared with the
83598227 PATENT
-9- computing resources represented in the latest version of the infrastructure template. As mentioned earlier, an infrastructure template represents various computing resources provisioned by an infrastructure provider, for instance upon a request received from a cloud service provider. A cloud service template may represent various computing resources that may be deployed for providing a cloud service to a subscriber. And, by way of non-limiting examples, the computing resources may include number of server groups, number of servers in a server group, cost of a server, a server resource (for example, CPU, memory, storage unit, etc.), an operating system, and architecture of the operating system.
[0023] To provide an illustration, in response to identifying a difference between the timestamp of the infrastructure template associated with the cloud service template and the timestamp of the latest version of the infrastructure template, the number of server groups present in the cloud service template may be compared with the number of server groups present in the latest version of the infrastructure template.
[0024] At block 206, in response to identifying a difference between computing resources represented in the cloud service template with computing resources represented in the latest version of the infrastructure template, the computing resources represented in the cloud service template are synchronized with the computing resources represented in the latest version of the infrastructure template.
[0025] In an implementation, synchronizing the computing resources represented in the cloud service template with the computing resources represented in the latest version of the infrastructure template includes adding and/or removing the computing resources in the cloud service template to correspond with the computing resources represented in the latest version of the infrastructure template. To provide an illustration, if upon comparison it is found
83598227 PATENT
-10- that additional server groups are present in the infrastructure template compared to the number of server groups in the cloud service template, additional server groups may be added to the cloud service template. Likewise, if some server groups have been removed from the latest version of the infrastructure template, corresponding server groups may be removed from the service template.
[0026] Similarly, other computing resources are compared between the cloud service template and the latest version of the infrastructure template and, in case any differences are identified, the cloud service template is updated so that the computing resources present therein correspond with the computing resources present in the infrastructure template. In an example, the cost of the servers in the infrastructure template is compared with the cost of the servers in the service template. If the costs are not same, pricing changes as necessary are applied to the service template.
[0027] In an implementation, the results of synchronization are displayed and/or notified to a user so that a necessary action may be taken. The results may include a summary of changes made to the cloud service template in response to a successful synchronization of the computing resources represented in the cloud service template with the computing resources represented in the latest version of the infrastructure template. The results could also include a summary of causes of failure in response to an unsuccessful synchronizing of the computing resources between the two templates. In case, the synchronization is successful, a user may be prompted to save the modified cloud service template.
[0028] FIG. 3 illustrates an example system 300 for synchronizing a cloud service template with an infrastructure template, according to an example. System 300 includes a processor 302 that executes instructions in a memory 304. The memory 304 includes a scheduler module 104 to compare a timestamp of an infrastructure template associated with a cloud service template with a timestamp
83598227 PATENT
-11- of a latest version of the infrastructure template. In response to identifying a difference between the timestamp of the infrastructure template associated with the cloud service template and the timestamp of the latest version of the infrastructure template, scheduler module 104 compares the computing resources represented in the cloud service template with the computing resources represented in the latest version of the infrastructure template. And, in response to identifying a difference between computing resources represented in the cloud service template with computing resources represented in the latest version of the infrastructure template, scheduler module 104 synchronizes the computing resources represented in the cloud service template with the computing resources represented in the latest version of the infrastructure template.
[0029] For the purpose of simplicity of explanation, the example method of FIG. 2 is shown as executing serially, however it is to be understood and appreciated that the present and other examples are not limited by the illustrated order. The example system of FIG. 1 and method of FIG. 2 may be implemented in the form of a computer program product including computer-executable instructions, such as program code, which may be run on any suitable computing environment in conjunction with a suitable operating system such as, but not limited to, Microsoft Windows, Linux or UNIX operating system. Embodiments within the scope of the present solution may also include program products comprising non-transitory computer-readable media for carrying or having computer-executable instructions or data structures stored thereon. Such computer-readable media can be any available media that can be accessed by a general purpose or special purpose computer. By way of example, such computer- readable media can comprise RAM, ROM, EPROM, EEPROM, CD-ROM, magnetic disk storage or other storage devices, or any other medium which can be used to carry or store desired program code in the form of computer-executable instructions and which can be accessed by a general purpose or special purpose
83598227 PATENT
-12- computer. The computer readable instructions can also be accessed from memory and be executed by a processor.
[0030] For the sake of clarity, the term "module", as used in this document, may mean to include a software component, a hardware component or a combination thereof. A module may include, by way of example, components, such as software components, processes, tasks, co-routines, functions, attributes, procedures, drivers, firmware, data, databases, data structures, Application Specific Integrated Circuits (ASIC) and other computing devices. The module may reside on a volatile or non-volatile storage medium and configured to interact with a processor of a computer system.
[0031] It would be appreciated that the system components depicted in the illustrated figures are for the purpose of illustration only and the actual components may vary depending on the computing system and architecture deployed for implementation of the present solution. The various components described above may be hosted on a single computing system or multiple computer systems, including servers, connected together through suitable means.
[0032] It should be noted that the above-described embodiment of the present solution is for the purpose of illustration only. Although the solution has been described in conjunction with a specific embodiment thereof, numerous modifications are possible without materially departing from the teachings and advantages of the subject matter described herein. Other substitutions, modifications and changes may be made without departing from the spirit of the present solution.
