Problems solved by technology

[0006] However, users want to be able to complete the migration without downtime, that is, during the migration process, the application needs to continue to provide external services and be able to read and write the database services provided by the underlying PaaS. The current downtime migration method obviously cannot meet the demand
In addition, during the migration process, users need to customize the underlying service status, which greatly increases the complexity of users using PaaS

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings. These implementation examples are described in sufficient detail to enable those skilled in the art to practice the invention. Logical, implementation and other changes may be made in the implementation without departing from the spirit and scope of the invention.

[0023] figure 1 is a schematic diagram of the architecture of the PaaS platform of the present invention, such as figure 1 As shown, in the PaaS platform, the resource pool is divided into multiple areas, which are called different autonomous domains (AZ, Availability Zone). Therefore, the network connectivity within the same AZ is relatively good, and the network connectivity between AZs is relatively good. relatively poor network connectivity. Each AZ is composed of several hosting nodes (Nodes), and each hosting node provides middleware services and application container services in the table ...

Abstract

The present invention provides a method and device for implementing application migration in a PaaS platform, including: determining the target bearer node of the migrated application; migrating the service function data of the migrated application in the source bearer node to the target bearer node; After the functional data migration is completed, the target bearer node receives the service request for the migrated application, and forwards the service request to the source bearer node for processing; migrates the underlying service data of the migrated application in the source bearer node to the target bearer node, and After the migration of the underlying service data of the migrated application is completed, the target bearer node receives the service request for the migrated application and processes the service request; deletes the underlying service data of the migrated application on the source bearer node. The present invention can complete migration without downtime.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to a method and device for implementing application migration in a Platform-as-a-Service (PaaS, Platform-as-a-Service) platform. Background technique [0002] With the fierce competition in the telecommunications market, operators are expanding new businesses one after another. Cloud computing is one of the new businesses being expanded. Among them, PaaS is a developer-oriented service that provides elastically scalable middleware services and application deployment platforms. In recent years, building PaaS platforms based on lightweight Linux containers has gradually become mainstream, such as the open source platform Cloud Foundry and Red Hat's OpenShift. Linux containers can well encapsulate various middleware systems and user applications. Users do not need to build middleware systems such as message middleware, databases, and application containers. They only ...
