LOAD BALANCING IN A SYSTEM

There is provided a method performed by an entity for load balancing in a system including a function-as-a-service (FaaS) system and a container-as-a-service (CaaS) system. The method is performed in response to a change in a load balancing configuration of a plurality of software containers of the CaaS system and/or a second load balancing configuration of a plurality of software functions of the FaaS system. Each software container is associated with a respective software function. The first load balancing configuration and second load balancing configuration are coordinated such that, following the change, each execution instance of one or more of the plurality software functions is subject to the same load balancing configuration as each instance of one or more of the plurality of software containers with which the one or more of the plurality of software functions is associated.
