FIG6 is a schematic flowchart of a method for providing a PaaS service according to another embodiment of this application
FIG6 is a schematic flowchart of a method 700 for providing a PaaS service according to an embodiment of this application. A scenario shown in FIG6 is a scenario in which a real tenant changes a PaaS instance. That a PaaS management system receives a PaaS operation request sent by a first real tenant in S510 may include: receiving, by the PaaS management system, a PaaS operation request that instructs to change a PaaS instance and that is sent by the first real tenant. That the PaaS management system controls, based on the PaaS operation request and the information about the first virtual tenant and by using the first virtual tenant, an infrastructure as a service IaaS management system to process an IaaS operation corresponding to the PaaS operation in S530 may include: determining, by the PaaS management system based on the PaaS operation request, that the IaaS operation corresponding to the PaaS operation is changing a parameter of the PaaS instance; and controlling, by the PaaS management system by using the first virtual tenant, the IaaS management system to change the parameter of the PaaS instance. As shown in FIG6, the scenario in which a real tenant changes a PaaS instance may include the following procedure.

['1. A method for providing a platform as a service PaaS service, wherein the method comprises: receiving, by a PaaS management system, a PaaS operation request sent by a first real tenant, wherein the PaaS operation request is used to indicate a PaaS operation intended for a PaaS resource; determining, by the PaaS management system, information about a first virtual tenant corresponding to the first real tenant, wherein there are one-to-one correspondences between real tenants and virtual tenants, and the first real tenant and the first virtual tenant are a pair in the one-to-one correspondences; and controlling, by the PaaS management system based on the PaaS operation request and the information about the first virtual tenant and by using the first virtual tenant, an infrastructure as a service IaaS management system to process an IaaS operation corresponding to the PaaS operation.']
