According to the three service modes of cloud computing, there are three modes of application in Information system simulation:
⑴ Infrastructure as Service (IaaS): Service Providers (operators) to provide infrastructure resources, such as virtual host/storage/network/database management, users do not need to purchase servers, network equipment and storage equipment, simply through the network (such as military network or civil Internet) application, approval, payment (or leasing), Can build their own application system. The service organization provides reliable and low-cost services such as mass data storage, data calculation, information processing and query messaging.
For information system simulation, this kind of service can effectively avoid the duplication investment of hardware construction, reduce the cost of resource use and application threshold, and promote the popularization of information system simulation.
⑵ Platform is a service (PaaS): Provides a software platform for user applications to run, and serves as a service to users, including software development testing, deployment, running environments, and application hosting services.
For information System simulation, the service type is suitable to build the simulation system of Army participation. Just imagine, if the higher institutions or strong technical strength of the research institutions can provide information system simulation system Platform data service engine, model building engine, model running engine, platform Management Service engine, System integration architecture and interface standardization, standardization, and even integration of solutions and services, it will not only improve the information system imitation The construction quality and application level of the real system will significantly improve the enthusiasm of the whole army to participate in the information system simulation construction, exert more talents, and can effectively reduce the cost of information system simulation from the repetitive research and development greatly reduced.
⑶ Software and Services (SaaS): "Software as a service" is the encapsulation of some specific application functions into services. A single instance of the software runs on the cloud and serves multiple end users or customer agencies. For information System simulation, the service type is the best way to unify the technical system and improve the information sharing degree. It is also an effective means to reduce "chimney" and "island".
