Research And Implementation Of Cloud Collaboration Platform Based On

Currently, hybrid cloud, cross-cloud and cloud federation become hot issues of cloud issues, which are closely related to cloud collaboration, the cause of the problem has two aspects, one is from the user perspective, users do not expect only Cloud services are provided only by a single cloud provider, they expect to be able to migration application service between mix cloud and private cloud, and with the change in their own business needs, the service bought on demand can be migrated in the cloud platform, another point is the cloud service provider, this point also contains two questions, one is that cloud resources provided by cloud provider are limited, when its resources cannot meet user service needs, you must cooperate with other cloud providers to achieve the possibility of unlimited resources, the second is collaboration for loading issue under the same cloud computing environment, when a cloud side workload exceeding a certain value, it must request cloud resources collaboration to ensure high quality and reliable service.It can be found that services running of across cloud computing platform and operating system differences and management software version differences and infrastructure divergence are all related to cloud collaboration. due to various problems of users and cloud providers, cloud interoperability standards really difficult to form, with the passage of time and the continuous development of technology, even to solve the problem of cloud collaboration, but migration between multiple cloud will lead to an issue of large number of data sets. This is because of latency that migrate data requires a certain amount of time, so the application migration issues associated with data storage migration.DDS-based publish-subscribe messaging model has the advantage of time loosely coupled, asynchronous receiver, in line with the distributed nature of cloud environments of multiple clouds, in order to solve the coordination problem of multiple cloud platforms and the data cloud side Frequent distribution problem, this paper presents a cloud collaboration platform based on DDS Data Distribution Service, the core of cloud collaboration platform architecture is cloud side agent, which in charge of cloud collaboration.This paper presents a hierarchical model of cloud agent, focusing on cloud resource monitoring layer and cloud data distribution layer, given the cloud party infrastructure resources meta-model and cloud resources monitor layer architecture for cloud party cooperation, the former is responsible for decision and execution cloud collaboration, the latter is responsible for publishing request cooperation, subscribing response coordination and all operation of data of publishing and subscribing.
