1. A system, comprising:
a memory to store instructions; and
a processor to execute the instructions to:
send a first heartbeat message to a virtual network function component instance (VNFCI) with an operational state of active and a desired operational state of shutdown;
receive a second heartbeat message from the VNFCI;
determine an operational state of the VNFCI when the second heartbeat message is received from the VNFCI;
control the VNFCI to stay in the active state when the operational state in the second heartbeat message is being activated;
transition the VNFCI to a state of being deactivated;
stop service traffic from being accepted at the VNFCI; and
transition to shutdown state at the VNFCI.
