Provided are a virtual machine deployment method and apparatus. The method comprises: acquiring a fragment node by scrambling and fragmenting to-be-processed data; allocating a target virtual machine to the fragment node according to the data amount of the fragment node; and deploying the fragment node onto the target virtual machine. In the present embodiment, when a virtual machine is allocated to a fragment node, the data amount of the fragment node is controlled firstly by scrambling data, and then a virtual machine matching the data amount is allocated according to the actual data amount so as to prevent the virtual machine from an overload phenomenon, thereby better achieving load balancing.
