State migration for elastic virtualized components

A capability for supporting an elastic virtualized component that is stateful is provided by supporting state migration for the elastic virtualized component. The elastic virtualized component may support a virtualized network function or any other suitable virtualized function. The elastic virtualized component includes a component load balancer and a set of component instances configured to provide functions of the elastic virtualized component. The elastic virtualized component may be configured to support migration of state information of the component instances following elasticity events in which the capacity of the elastic virtualized component changes (e.g., in response to growth events in which the number of component instances of which the elastic virtualized component is composed increases, in response to degrowth events in which the number of component instances of which the elastic virtualized component is composed decreases, or the like).
