According to the method, a resource capacity allocation of a network instance is determined and a resource capacity demand of the network instance is monitored. If the resource capacity demand exceeds a first threshold value, the resource capacity allocation of the network instance is increased by allocating additional resource capacity of a shared pool of network instances. However, if the resource capacity demand falls below a second threshold value, the resource capacity allocation of the network instance is decreased by deallocating the additional resource capacity back to the shared pool of network instances. ## Claims ### Claim 1 A method for dynamic allocating of a resource capacity in a cloud computing deployment, the method comprising: receiving an allocation request from a network instance generated during a pre-boot operation of the network instance, the allocation request being based on a predicted traffic demand of the network instance, wherein the network instance includes a network device connected to a data network;
