Abstract: A service deployment method determining an execution path of a to-be-deployed service, the execution path includes a first execution device and a second execution device; obtaining a first quality of service (QoS) of the first execution device; obtaining a second QoS of the second execution device; calculating a third QoS of the execution path based on the first QoS and the second QoS; obtaining a preset QoS of the to-be-deployed service; making a first determination that a first relationship between the third QoS and the preset QoS meets a preset rule; and deploying, in response to the first determination, the to-be-deployed service on the execution path.
