Redundant service deployment method and device

Abstract

The embodiment of the invention provides a redundant service deployment method and device. The redundant service deployment method comprises the following steps: determining multiple to-be-deployed services contained in an application program request of a user, a resource demand of each to-be-deployed service and a communication delay demand among the to-be-deployed services, wherein each to-be-deployed service comprises a plurality of service copies; based on a preset service placement rule, allocating a physical machine node to each service copy of each service to be deployed, and screeningout a plurality of available placement decisions; calculating the reliability of the available placement decision according to the reliability of the physical machine node placed by the service copy of each to-be-deployed service and the reliability of the micro cloud; determining a final placement decision from the available placement decisions; and deploying the corresponding to-be-deployed service in the physical machine node of the micro-cloud based on the final placement decision. The resource requirement of each service of the application program, the inter-service communication requirement, the reliability of the physical machine node and the reliability factor of the micro cloud are comprehensively considered, and the high reliability of service deployment is ensured.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a redundant service deployment method and device. Background technique [0002] In recent years, with the continuous development of informatization and networking, information systems have played an increasingly important role in military, disaster relief and other fields. In this highly dynamic environment, mission plans and equipment composition may change frequently, and network connectivity may fluctuate. The service resources based on stand-alone devices are very limited and cannot cope with complex computing tasks. Cloud computing technology is an effective means to deal with this scenario. In cloud computing technology, resource configuration can be customized according to task requirements, so as to provide convenient and flexible management services for large-scale applications. However, traditional cloud platforms are usually deployed in areas f...

Problems solved by technology

[0005] In addition, when deploying services, not only the resource requirements of each service, but also the communication requirements between services need to be considered, which further increases the complexity of service deployment

However, the existing service deployment in the federated micro-cloud field does not consider the inter-service communication requirements
