Method and apparatus for deploying SaaS software in cloud environment

Abstract

The invention discloses a method for deploying SaaS software in a cloud environment. The method comprises the following steps of obtaining a lease of at least one lessee to the SaaS software; according to the lease, determining information of the SaaS software needed to be deployed; according to a leased infrastructure status, determining leasable virtual machine information; according to the SaaS software information and the virtual machine information, determining a deployment scheme, wherein the deployment scheme contains SaaS software instance quantities of all types, virtual machine instance quantities of all types, corresponding relationships between lessees and SaaS software instances, and corresponding relationships between the SaaS software instances and virtual machine instances, and the total lease cost of virtual machines corresponding to the deployment scheme is minimal; and performing SaaS software deployment according to the deployment scheme. By applying the technical scheme provided by the method, the lease cost of an SaaS service provider can be reduced and the resource utilization rate can be increased. The invention furthermore discloses an apparatus for deploying the SaaS software in the cloud environment. The apparatus has the corresponding technical effects.

Description

technical field [0001] The present invention relates to the technical field of cloud computing, in particular to a method and device for deploying SaaS software in a cloud environment. Background technique [0002] With the rapid development of cloud computing technology, the SaaS (Software-as-a-Service, Software as a Service) model is gradually emerging. The SaaS model is a service provided by cloud computing at the application layer. In the SaaS mode, customers do not need to purchase a complete software system, nor need to be equipped with corresponding hardware systems and maintenance personnel. They only need to rent application software on demand through the Internet, which is suitable for small and medium enterprises with limited cost budget and insufficient technical conditions. Enterprises are very attractive. [0003] In the cloud environment, the SaaS model mainly involves three types of roles: tenants, SaaS service providers and infrastructure providers. Tenan...
