1. A computer-implemented method comprising: selecting a first security microservice of a first level of a hierarchy of security microservices; configuring security microservices of a second lower-level of the hierarchy of security microservices to remove the first security microservice from load balancing decisions to the first level of the hierarchy of security microservices; moving the first security microservice to another server; configuring data plane connectivity to the first security microservice to reflect a change in servers; configuring the security microservices of the second lower-level of the hierarchy of security microservices to include the first security microservice in load balancing decisions to the second lower-level of the hierarchy of security microservices; and processing a packet from a flow of packets with the first security microservice, wherein each level of the hierarchy of security microservices performs a different security operation.
