The present disclosure provides virtual machine deployment methods and apparatuses. One exemplary virtual machine deployment 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. According to some embodiments of the present disclosure, when a virtual machine is allocated to a fragment node, the data amount of the fragment node can be controlled firstly by scrambling data. Then a virtual machine matching the data amount can be allocated according to the actual data amount of the fragment node, so as to prevent the virtual machine from overloading, thereby achieving better load balancing.
