Description

FIELD

Embodiments of the present invention relate to resource allocation, and more specifically, to a method and apparatus for providing computing resources to a user.

BACKGROUND

The development of the Internet technology brings about convenience to human work and life, and meanwhile, the concept of providing various services based on the Internet becomes popular with the increasing improvement of the Internet transmission efficiency. For example, so far there has been proposed the concept of Infrastructure as a Service (IaaS), i.e., a service that ordinary users (e.g., including individuals or companies or other entities) can obtain via the Internet computer infrastructure meeting their own demands. In addition, there have been further proposed the concept of Platform as a Service (PaaS) and the concept of Software as a Service (SaaS), so users can obtain via the Internet services from professional platform providers or software providers.

These service providers can customize and provide services according to users' specific demands, so that users can obtain various professional services (e.g., including infrastructure, platform and software) via the Internet. However, ordinary users (e.g., hospitals, shops, etc.) desiring to construct IT infrastructure (e.g., a datacenter) might lack expertise in hardware configuration and other aspect. As a result, although there are various service providers on the Internet, these ordinary users might not be aware of their own demands for hardware and software, let alone learn which service provider or providers are applied to for what kinds of computing resources while constructing IT infrastructure.

As restricted by their own knowledge, users have to turn to professional technicians for help while constructing IT infrastructure. On the one hand, this brings about to users huge overheads of manpower, material resources and time; on the other hand, professional technicians need to customize a solution for each user, and the reusability of these solutions is rather bad. Therefore, it has become a focus of attention as to how to provide appropriate IT infrastructure to a user where the user's demand is not quite clear.

SUMMARY

Therefore, it is desired to develop a solution capable of automatically providing customized IT infrastructure to a user, and it is desired that the technical solution can provide to the user IT infrastructure formed by various computing resources simply by requiring the user to provide simple information (e.g., providing industrial information on the user's domain and the user's scale information); further, it is desired that the user does not have to care about the physical positions or providers of these computing resources.

In one embodiment of the present invention, there is provided a method for providing computing resources to a user, comprising: in response to a request from the user, looking up in a profile repository a profile corresponding to the user's domain information; requesting at least one computing resource associated with the profile; integrating the at least one computing resource into a virtual datacenter; and providing the virtual datacenter to the user; wherein the at least one computing resource is physically deployed in a distributed manner.

In one embodiment of the present invention, the requesting at least one computing resource associated with the profile comprises: with respect to one computing resource of the at least one computing resource, parsing logical description of the computing resource; and in response to in a resource pool there existing an available resource corresponding to the logical description, providing the available resource as the computing resource.

In one embodiment of the present invention, there is further comprised: in response to in a resource pool there existing no available resource corresponding to the logical description, mapping the logical description to one of at least one resource provider; and requesting the computing resource from the one of the at least one resource provider.

In one embodiment of the present invention, there is provided an apparatus for providing computer resources to a user, comprising: a lookup module configured to in response to a request from the user, look up in a profile repository a profile corresponding to the user's information; a requesting module configured to request at least one computing resource associated with the profile; an integrating module configured to integrate the at least one computing resource into a virtual datacenter; and a providing module configured to provide the virtual datacenter to the user; wherein the at least one computing resource is physically deployed in a distributed manner.

In one embodiment of the present invention, the requesting module comprises: a parsing module configured to with respect to one computing resource of the at least one computing resource, parse logical description of the computing resource; and an internal providing module configured to in response to in a resource pool there existing an available resource corresponding to the logical description, provide the available resource as the computing resource.

In one embodiment of the present invention, there is further comprised: a mapping module configured to in response to in a resource pool there existing no available resource corresponding to the logical description, map the logical description to one of at least one resource provider; and an external providing module configured to request the computing resource from the one of the at least one resource provider.

By means of the technical solution described in the present invention, various computing resources can be automatically requested from corresponding service providers according to a user's domain information and scale information, and the user does not have to care about the sources and physical positions of various computing resources or how these computing resources are organized together. The technical solution described in the present invention can integrate various computing resources provided on the Internet, and even a user without any professional experience can enjoy various services provided via the Internet. Therefore, the utilization efficiency of various services provided based on the Internet can be improved, whereas the requirement on users' professional experience can be lowered.

Hereinafter, terms involved in various embodiments of the present invention are explained first.

Infrastructure as a Service (IaaS): the capability of providing to a consumer processing, storage, network, and other basic computing resources where the consumer is able to deploy and run arbitrary software, wherein the software can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of selected networking components (e.g., host firewalls).

Platform as a Service (PaaS): the capability, as provided to the consumer, of deploying consumer-created or acquired applications onto the cloud infrastructure. Such applications are created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Software as a Service (SaaS): the capability, as provided to the consumer, of using the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

FIG. 2 schematically illustrates a schematic view 200 of the architecture of a datacenter according to one solution. As illustrated in FIG. 2, a traditional datacenter is usually located at the same physical place where a user is located (e.g., a hospital). For example, a file storage system 210, a main system 212, . . . , and an employee management system 214 are usually in the hospital, and staff of the hospital can access these systems via workstations 1 . . . M 222 and desktop systems 1 . . . N 220 which are also located within the hospital scope. Various devices that are physically located within the hospital scope jointly form a datacenter of the hospital. To build such a datacenter, it is necessary to purchase hardware devices and software products, and to have the datacenter operate normally, it is further necessary to configure hardware devices, install software products and the like.

FIG. 3 schematically illustrates a schematic view 300 of the architecture of a virtual datacenter according to principles of the present invention. Based on the principles of the present invention, a user datacenter is not necessarily physically located in the vicinity of the user. Instead, the datacenter can be formed by various computing resources that are accessible via the Internet, i.e., formed by some computing nodes in a cloud environment. Specifically, a file storage system 310, an e-mail system 312, . . . , an employee management system 314, virtual desktop systems 1 . . . N 320 and virtual workstations 1 . . . M 322 can be physically located at any place that is accessible via a network 330. Staff of the hospital can access and use these systems via the Internet.

The above merely depicts a user's demand (such as a hospital) on building a datacenter. Note users in the same domain usually have similar demands for configuring a datacenter. For example, the IT infrastructure of a medical organization usually includes a medical case management system, object storage and other resources; the IT infrastructure of a software development entity usually includes resources such as a code version control system, a project management system and the like. Therefore, it becomes a hot issue regarding how to automatically provide a user with a configuration scheme of IT infrastructure based on the user's domain. In this manner, it is possible to provide a user with proposals concerning IT infrastructure configuration and further to achieve the IT infrastructure, in the case that the user's demand is not quite clear.

In one embodiment of the present invention, there is provided a method for providing computing resources to a user, comprising: in response to a request from the user, looking up in a profile repository a profile corresponding to the user's domain information; requesting at least one computing resource associated with the profile; integrating the at least one computing resource into a virtual datacenter; and providing the virtual datacenter to the user; wherein the at least one computing resource is physically deployed in a distributed manner.

FIG. 4 schematically illustrates a flowchart 400 of a method for providing computing resources to a user according to one embodiment of the present invention. Specifically, in step S402, in response to a request from the user, a profile corresponding to the user's domain information is looked up in a profile repository. In one embodiment of the present invention, configurations of computing resources that are applicable to datacenters of users in various domains can be stored in the profile repository. Specifically, configurations of computing resources for a hospital and a software development entity are schematically illustrated in Table 1 below.

TABLE 1
Configurations of Computing Resources
domain	scale	configurations of computing resources
hospital	n	virtual desktop (1 G CPU/512M Memory/20 G
		Storage/Single Network Interface Card) n*120%
		virtual workstation (4 G CPU/2 G Memory/50 G
		Memory/Dual Network Interface Card) n*15%
		shared virtual block storage (n*10 G)
		object storage (n*40 G)

		e-mail service system
software	n	virtual desktop (2 G CPU/1 G Memory/40 G

		virtual workstation (4 G CPU/2 G Memory/100 G
		Storage/Dual Network Interface Card) n*20%
		shared virtual block storage (n*20 G)
		shared file storage (n*20 G)
		code version control system
		document sharing and publishing system
		project management system
		Bug management system
		FTP system
		application deployment platform
		employee management system
		financial reimbursement system
		e-mail service system

According to one embodiment of the present invention, since users in the same domain have similar demands for computing resources of datacenters, a user simply needs to input the domain to which he/she belongs, desired resource configurations can be recommended to the user according to a predefined profile. Specifically, when a user inputs “hospital,” a profile corresponding to “hospital” can be looked up in the profile repository as illustrated in Table 1.

In step S404, at least one computing resource associated with the profile is requested, wherein the at least one computing resource is physically deployed in a distributed manner. After obtaining a profile corresponding to the user's domain, computing resources associated with the profile are requested. Note the amount and type of computing resources are not limited in the context of the present invention. For example, the computing resources can be those that are accessible via the Internet, including, without limitation, infrastructures, platforms, software, etc. Further note the context of the present invention does not limit which provider or providers provide(s) these computing resources. The computing resources provided to one user can be resources provided by the same or different providers, and physical positions of these providers are transparent to customers, so long as the user can access these resources via the Internet.

In the above example where the user is a hospital, the following hardware resources can be requested from the infrastructure provider: virtual desktop (1G CPU/512M Memory/20G Storage/Single Network Interface Card); virtual workstation (4G CPU/2G Memory/50G Storage/Dual Network Interface Card); shared virtual block storage (n*10G); and object storage (n*40G). Further the following platform and/or software resources can be requested from the platform and/or software provider: medical case management system, employee management system, financial reimbursement system, and e-mail service system.

In step S406, the at least one computing resource is integrated into a virtual datacenter. Note in order to provide the user with a virtual datacenter that is logically accessible, it is necessary to integrate various requested computing resources, rather than providing the user with scattered computing resources. For example, it may be checked whether various computing resources defined in profiles have been requested, and an interface may be provided to the user for supporting the user to query information in the virtual datacenter and the status of computing resources included in the virtual datacenter. For another example, the user may be billed based on the kind, amount and other factor of computing resources provided to the user.

Finally in step S408, the virtual datacenter is provided to the user. The datacenter here is a virtual datacenter that is logically accessible by the user. The user does not have to care about the physical position of various computing resources in the datacenter but can achieve access via the Internet. With the technical solution of the virtual datacenter, the user does not have to build a special computer room for various devices of the datacenter or purchase various hardware devices for usage as IT infrastructure of the datacenter, but the user simply needs to have the capability to access various hardware and software services via the high-speed Internet. Note the context of the present invention does not care about concrete details of IaaS, PaaS and SaaS providers and the high-speed Internet implementation, but only cares about how to use and integrate these services provided via the Internet.

Authentication, authorization and various techniques that are currently known or will be developed in future may be leveraged in order to ensure the security while the user is using the virtual datacenter.

In one embodiment of the present invention, the looking up in a profile repository a profile corresponding to the user's domain information further comprises: adjusting the profile based on the user's scale information. Since users' scales might differ widely, the amounts of needed computing resources may also differ significantly. For example, regarding the numbers of virtual desktops and virtual workstations, the requirement of a hospital with 100 staff may differ from that of a hospital with 200 staff. Therefore, the profile may be adjusted based on the user's scale information.

In addition, the user might further modify the amount and kind of computing resources in the profile based on his/her own demand. In one embodiment of the present invention, the looking up in a profile repository a profile corresponding to the user's domain information comprises: modifying the profile in response to an input from the user. Specifically, the profile as illustrated in Table 1 may be prompted to a user belonging to the “hospital” domain; where “e-mail service system” has been built, the user may cancel the “e-mail service system” option in the profile so as to avoid duplicated investment.

In one embodiment of the present invention, if in the profile repository there is no profile that completely matches the user's domain, then a domain that is closest to the user's domain is searched for in the profile repository, and a profile that describes optional computing resources is prompted to the user. For example, a basic profile (as illustrated in Table 2 below) that is suitable to ordinary enterprises may be preset in the profile repository. The user can add or delete some computing resources on the basis of the basic profile as demanded; in addition, recommendations for modifying the profile may be automatically provided to the user based on the user demand and an expert knowledge repository.

TABLE 2
Configurations of Computing Resources
Domain	scale	configurations of computing resources
ordinary	n	virtual desktop (1 G CPU/512M Memory/20 G
enterprise		Storage/Single Network Interface Card) n*120%
		virtual workstation (4 G CPU/2 G Memory/50 G
		Storage/Dual Network Interface Card) n*15%
		shared virtual block storage (n*10 G)
		object storage (n*40 G)
		employee management system
		financial reimbursement system
		e-mail service system

In one embodiment of the present invention, there is further comprised: updating the profile repository using the modified profile. After a profile that is suitable for the user's domain and scale is customized based on the user demand and an expert knowledge repository, the profile may be updated into the profile repository so as to serve as a basis for possible future queries.

FIG. 5 schematically illustrates a schematic view 500 of the architecture of a virtual datacenter according to one embodiment of the present invention. As illustrated in FIG. 5, a file memory system 510, an e-mail system 512, . . . , an employee management system 514, virtual desktop systems 1 . . . N 520 and virtual workstations 1 . . . M 522 may be located at any position that is accessible via the Internet, and may be provided by the same or different service providers. With the method described with reference to FIG. 4, these computing resources may be integrated into a virtual datacenter 540 and provided to users.

Specifically, different users can access virtual datacenters that are customized according to their own demands. Since computing resources in the virtual datacenter may come from the same or different service providers, huge extensibility is provided for providing a virtual datacenter by using the technical solution of the present invention. For example, when the user demand changes (for example, desiring to increase the number of virtual desktops), a request may be made to the same or different virtual desktop providers. For another example, when a user in the hospital domain wishes to build an FTP system, then a request is submitted to only a service provider providing an FTP system.

In one embodiment of the present invention, the requesting at least one computing resource associated with the profile comprises: with respect to one computing resource of the at least one computing resource, parsing logical description of the computing resource; and in response to in a resource pool there existing an available resource corresponding to the logical description, providing the available resource as the computing resource.

Logical description of a computing resource may define which computing resource is obtained from which service provider/providers. For example, logical description of a computing resource may be defined using the format as illustrated in Table 3 below.

TABLE 3
Logical Description
	No.	computing resource	logical description
	1	virtual desktop	resource pool-VM; and/or
			Amazon Web service-VM
	2	virtual workstation	Amazon Web service-VM
	. . .	. . .	. . .
	N	employee	Salesforce-employee
		management system	management system

In this embodiment a resource pool may be built. For example, computing resources may be requested in advance to resource providers (e.g., IaaS, PaaS and SaaS service providers) for later use, or after a specific user releases a computing resource of the virtual datacenter, the released resource is not immediately returned to the resource provider but is cached in the resource pool for later use. For example, in the logical description illustrated in Table 3, it is defined that a virtual desktop may be requested from a resource pool and/or Amazon Web service. Thus, it may be checked first whether or not an available resource corresponding to the logical description exists in the resource pool, and in response to a “Yes” result, the available resource is provided as the computing resource.

In one embodiment of the present invention, there is further comprised: in response to in a resource pool there existing no available resource corresponding to the logical description, mapping the logical description to one of at least one resource provider; and requesting the computing resource from the one of the at least one resource provider.

Continue the above example. When no virtual desktop exists in the resource pool or computing resources in the resource pool are not enough to meet the user demand, a request for resource allocation may be submitted to Amazon Web service. The requesting for resource allocation to a resource provider is similar to the requesting in the prior art, so various details are omitted here. An advantage of using the technical solution described in the present invention is that resource requesting and allocation are transparent to a user, and the user does not need to learn about the physical position of a computing resource being used or care about tedious operations involved while requesting and allocating resources.

In the foregoing description, the requesting and allocating computing resources have been illustrated by taking Amazon Web service and Salesforce as examples of resource providers. Those skilled in the art would appreciate that in the embodiments of the present invention, computing resource providers may include any providers of infrastructure, platform and software that can be obtained via the Internet.

In one embodiment of the present invention, there is further comprised: monitoring a running status of the at least one resource provider; and filtering the at least one resource provider based on the running status. To learn about the stability and other features of various resource providers, the running status of the resource provider may be monitored in real time, so that when requesting a computer resource later, a resource provider with relatively stable running status may be a priority if there are a plurality of alternative resource providers.

In one embodiment of the present invention, the providing the virtual datacenter to the user comprises: providing to the user at least one address associated with the at least one computing resource; and in response to the user accessing one of the addresses, invoking a computing resource associated with the address. For example, an address (e.g., may be in the form of URL) list as illustrated in Table 4 below may be provided to the user, and a username and password for accessing the address may be further provided so as to support the user to access a corresponding computing resource.

TABLE 4
Address List
	computing
No.	resource	address	username	password
1	virtual	www.***.com/desktop/	Admin	###
	desktop
2	virtual	www.***.com/workstation/	Admin	###
	workstation
. . .	. . .	. . .
N	employee	www.***.com/managesys/	Admin	###
	management
	system

When the user desires to access various computing resources, he/she may input an address illustrated in Table 4 and invoke a c computing resource simply by using a corresponding username and password. For example, when the user desires to query information on an employee Alan in the employee management system, he/she may use a username “Admin” and password “###” to log into www.***.com/managesys/, thereby making a query in following pages.

In one embodiment of the present invention, the providing the virtual datacenter to the user comprises: forwarding the interaction between the user and the at least one computing resource. Note that the virtual datacenter provided according to the technical solution of the present invention is an interface between the user and the at least one resource provider that is accessible via the Internet, and the user can logically access various computing resources in the virtual datacenter without a need to learn about the real physical position of various computing resources. Therefore, the interaction between the user and the at least one computing resource may be forwarded, so as to support the user to interact with real computing resources that form the virtual center.

Specifically, FIG. 6 schematically illustrates a block diagram 60 of the interaction between the user and the virtual datacenter according to one embodiment of the present invention. For example, a forwarding module 620 may be disposed in the virtual datacenter for forwarding the interaction between the user and the at least one computing resource. For example, when a user (e.g., a software development company) wants to query the information of an employee Alan in an employee management system, a query request may be submitted from a user 610 to a forwarding module 620 (as illustrated by arrow A). In response to receipt of the query request, the forwarding module 620 immediately forwards the query quest to an employee management system 630 that is accessible via the Internet (as illustrated by arrow B). Next, employee management system 630 returns a query result to the forwarding module 620 (as illustrated by arrow C), and then the forwarding module 620 forwards the query result to the user 610 (as illustrated by arrow D). At this point, although the query request from the user 610 and the query result from an employee management system 630 are forwarded by the forwarding module 620, such forwarding procedure is transparent from the perspective of the user 610.

In one embodiment of the present invention, the providing the virtual datacenter to the user further comprises: monitoring a status of the at least one computing resource; and in response to a fault occurring in one of the at least one computing resource, repairing the computing resource.

Specifically, although the resource provider monitors in real time the running status of the computing resource provided by himself, to improve the reliability and stability of the virtual datacenter, further the running status of each computing resource in the virtual datacenter can be monitored in real time or periodically. For example, collecting the device information of hardware infrastructure (e.g., CPU workload, temperature, etc.), and collecting a response time and other parameters of a software computing resource so that when a specific computing resource breaks down, the resource provider can be notified in time and on the other hand, a remedy can be taken using other currently available computing resource. For example, when a VM corresponding to a certain virtual workstation stops the service, it is possible to try recovery from periodical mirroring of the VM.

In one embodiment of the present invention, the computing resources comprise any one of infrastructure, platform and software. With the technical solution described in the present invention, services of various IaaS, PaaS and SaaS providers as provided on the Internet currently can be integrated and provided to users in the form of a virtual datacenter. In this manner, the technical threshold that ordinary users request services to various service providers can be lowered, and on the other hand, the resource utilization efficiency of service providers can be improved greatly, and further overheads on manpower, material resources and time which ordinary users spend in building a datacenter can be reduced significantly.
