The IaaS layer mainly adopts a virtualized software technology and a chip support capability, the storage and computing resource (CPU, memory, I/O and the like) capabilities are divided according to the configurable minimum granularity to form independent virtual equipment images, and unified backup and migration mechanisms are arranged among the virtual equipment. The IaaS layer provides a uniform API (Application Programming Interface) to the outside, so as to implement uniform scheduling and sharing of storage resources and computing resources. An example of a specific IaaS layer implementation is shown in fig. 5.
The PaaS layer integrates various existing service capabilities and can be classified into an application server, service capability access, a service engine and a service open platform; measuring and calculating basic service capacity downwards according to the business capacity requirement; through API provided by IaaS, calling hardware resources, providing service dispatching center service upwards, monitoring various resources of the platform in real time, and opening the resources to SaaS users through API. In the three-layer architecture, PaaS is the direct embodiment of the core capability of the service.

The basic applications include traditional telecommunication service capabilities such as unified portals, multimedia, voice, data, etc., and the multi-tenant applications include personal applications, enterprise applications, communities and mobile stores, etc. The multi-tenant service is applied more on the internet, application examples among different tenants can be shared and load balanced, but the application is less in the telecommunication field, and the development mode of the telecommunication service can be optimized by introducing a SaaS new technology.
The IT resource support system provided by the invention can be applied to the field of telecommunications, and can help telecommunications operators to complete the technical transformation of the IT system by means of a novel cloud computing technology. The method has the following beneficial effects: (1) the existing telecommunication IT basic resources are integrated through a virtualization technology, a physical server is virtualized into a plurality of isolated virtual machines, different systems run in different virtual machines, and a plurality of sets of business systems share a basic physical platform, so that the utilization rate of the telecommunication IT resources is improved, an IT architecture of a machine room is simplified, and IT investment is protected. (2) As shown in fig. 6, a large number of cheap physical servers are integrated into a supercomputer with super-large-scale computing capability and mass data storage capability by using a distributed technology, so that large computing tasks such as operation data mining analysis, information processing service and the like which cannot be completed by a single physical computer originally can be solved, and meanwhile, a large system such as network management, charging and the like which is operated in a small computer cluster traditionally can be tried to be transformed and deployed to a low-cost PC server cluster by using a cloud computing distributed technology, so that the construction cost is reduced and the expansibility of the system is improved. (3) The existing telecommunication IT supporting system is modified by using SaaS technologies such as Web 2.0, SOAP and the like, and zero installation, zero maintenance and high expandability of various applications are realized.
The following describes embodiments of the above-mentioned IT resource supporting system provided by the present invention in combination with a specific IT resource supporting system architecture method. As shown in fig. 7, the architecture method of each of the above IT resource support system embodiments provided by the present invention can be specifically implemented by the following steps:
step S1, virtualizing the hardware device into a virtual device;
step S2, creating a management strategy for managing the hardware equipment and the virtual equipment;
step S3, creating a service interface;
step S4, constructing a resource bottom layer based on the steps S1 to S3;
step S5, creating application service, and constructing a management middle layer based on the created application service;
and step S6, constructing an upper-layer service interaction platform for presenting each application service.
By the IT resource support system architecture method, an open IT resource support system can be realized, unified scheduling and elastic allocation of IT resources are realized, software and hardware separation is realized, resources and a platform are integrated, and the IT resource support system can quickly and flexibly respond to the requirements of various service requests.
In a specific implementation, the step S1 may use an existing virtualization technology, that is, a virtualization host or a proxy task executor may be installed on a computer to create a virtual device. The generation of the virtual device is completed in step S1. The hardware equipment and the virtual equipment form basic equipment resources of the resource bottom layer. Step S2 may implement unified management of physical devices and virtual devices by combining IaaS technology. Step S3 may implement creation of a Service interface through a Service-Oriented Architecture (SOA) technology in a web Service manner in the prior art. Step S6 may combine with the existing App Store schema to construct an upper-layer service interaction platform for presenting application services.
Further, in order to maintain the operation security of the hardware device and the virtual device, in the implementation process, the management policy includes: storing and maintaining a management strategy of the mapping relation from the virtual equipment to the hardware equipment; or the management policy further comprises: a resource operation and maintenance management strategy and a security monitoring management strategy.
Still further, in the implementation process, the creating of the application service, and the building of the management middle layer based on the created application service are specifically implemented as follows, as shown in fig. 8:
s501, creating a middleware instance and generating a middleware resource pool;
step S502, creating a database instance and generating a database resource pool;
step S503, establishing a WEB service instance, and generating a WEB service resource pool;
step S504, based on the generated resource pools, establishing deployment, management and maintenance strategies for each instance in each resource pool;
step S505, constructing a management middle layer based on the above steps S501 to S504.
The construction of the management middle layer can be based on a PaaS technology, various existing business capabilities are integrated, the management middle layer can be specifically classified into an application server, a business capability access, a business engine and a business open platform, the basic service capability is measured and calculated downwards according to the business capability requirement, hardware resources are called through an API provided by IaaS, and an open interface is provided upwards through the API to SaaS users. The most fundamental difference between the services provided by PaaS and other services is that PaaS provides a basic platform rather than an application. The essence of PaaS is to serve resources as a programmable interface, and provide resources and a service platform for upper-layer business development.
Here, it should be noted that: the SOA technique mentioned above is a component model that links different functional units (or services) of an application through well-defined interfaces and contracts between these services. The definition of the interface is independent of the hardware platform, operating system, and programming language that implement the service. Services built into such systems can interact in a uniform and versatile manner. Defining a feature through an interface is referred to as loose coupling between services. The benefits of a loosely coupled system are two points, one is its flexibility and the other is that it can survive as the internal structure and implementation of each service that makes up the entire application changes gradually.
An open architecture for realizing a telecommunication IT resource support system based on SOA and PaaS technologies is an important technology which accords with centralized management and IT centralization at present and is a trend of development of telecommunication IT architectures in the future.
Those of ordinary skill in the art will understand that: all or a portion of the steps of implementing the above-described method embodiments may be performed by hardware associated with program instructions. The program may be stored in a computer-readable storage medium. When executed, the program performs steps comprising the method embodiments described above; and the aforementioned storage medium includes: various media that can store program codes, such as ROM, RAM, magnetic or optical disks.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
