Method for deploying services in cloud computing environment

Abstract

The invention discloses a method for deploying services in cloud computing environment. The method the following steps: a developer describes the provided service through using a cloud platform service definition language conceptual schema definition language (CSDL) defined by the invention, submits the service to a cloud platform; the cloud platform selects an optimal node deployment server according to the cloud node and the load of the service, and generates a search rule according to the CSDL; and a service user searches available services and calls the available services through accessing a cloud service warehouse. The system also provides a standby deployment system for ensuring the robustness, and periodically inspects the operation condition of the cloud node; the redeployment service reaches optimization; and by utilizing the method, the cloud platform is enabled to have higher service efficiency and fault tolerance; and in the cloud environment, the service provider does notneed maintain the environment of service operation by self, and submits the service to the cloud environment.

Description

technical field [0001] The present invention relates to the field of computer application technology, and in particular to a method for deploying services in a cloud computing environment for service deployment in a software as a service platform (Software as a Service, SaaS). Background technique [0002] Cloud computing in a narrow sense refers to the delivery and use mode of IT infrastructure, which refers to obtaining the required resources through the network in an on-demand and easy-to-expand manner; way to obtain the required services. Such services can be IT and software, Internet related, or other services. Cloud Computing is Grid Computing, Distributed Computing, Parallel Computing, Utility Computing, Network Storage Technologies, Virtualization, It is the product of the integration of traditional computer and network technologies such as Load Balance. [0003] Because cloud computing technology is an important part of the new generation of information technolog...

Problems solved by technology

[0011] 1. The traditional SOA description language WSDL is not suitable for the cloud environment. Information such as service IP addresses and ports in WSDL has no meaning in the cloud environment, because the cloud is transparent to users and service providers. , it is impossible for the user to know which node in the cloud saves and runs the service, let alone the IP address; in addition, the information such as the handle of some virtual storage required in the cloud environment is currently not provided by WSDL

[0012] 2. Traditional SOA requires one or several Web Service containers, such as IBM's Web Sphere, and service developers explicitly deploy services in Web Service containers; in a cloud environment, service developers do not know that the service is running The physical location of the cloud platform; and for the cloud platform, each cloud node has the ability to deploy the service, so how to choose the node to deploy is the first problem to be solved by the cloud platform. In addition, in the cloud environment, node failure is often Occurs, the service deployment system must not only select an optimal deployment node, but also do a certain amount of redundant deployment

[0013] 3. The traditional SOA deployment is fixedly running in the Web Service container, even if the service response time is very slow and the service quality is extremely low, it will continue to run
