B5. And for the scene that a plurality of users use the cluster resource simultaneously, the access right management and resource isolation functions are provided, the users cannot override other cluster resources except the cluster resource, and otherwise, an error prompt is returned.
Because the realized operation interface is simple and visual enough, the Kubernetese API operation details are shielded, so that a user can use the Kubernetese API without deep enough knowledge, and the use threshold of a developer is greatly reduced.
The step C comprises the following specific steps:

C6. Designing a service application process, namely configuring independent or shared platform resources, service application and approval processes on a plurality of levels of organizations or projects.
C7. The tenant creates a service request form, and enters a service approval process after filling parameters and requirements. If the rejected application needs to modify the application content and then resubmit the application content, if the rejected application is successful, the service can be directly created, and the service can be used on the application form according to the prompt of the output item.
C8. A cloud native tool chain is integrated with a large number of third-party tools, and development of test resources and environment delivery are accelerated.
C9. For the scenario that the application service is commonly used by multiple tenants, the platform on top of the application has the capacity of multi-tenant management, namely environment resource isolation and sharing.
C10. Information aggregation is carried out according to the use condition of the tenant on the cloud computing resource so as to provide an analysis function; data analysis comes from the management of application services to provide sufficient support for platform operation decisions. The analysis function comprises expense analysis, metering analysis, expenditure prediction and cost optimization.

D5. Automatically occurring failover and recovery: the platform key component adopts a ZooKeeper heartbeat mechanism to realize survival state monitoring. The component service instance is mounted as a ZooKeeper sequential node, and when the service instance is connected overtime and the client session fails due to a fault, the service instance is replaced by a subsequent node to continue providing service. And when the service instance is recovered to be normal, the service instance is reinstalled to the ZooKeeper, and the node can be replaced at any time to provide service.
The method supports various deployment architectures, various middleware selections and automatic fault transfer and recovery, ensures that single-point faults can be avoided, can continuously and stably support the service, and can also be quickly and conveniently expanded along with the increase of the service.
