The software for the monitoring and control system is developed based on the TANGO-controls framework, which provide a distributed architecture for driving software and hardware using CORBA distributed objects that represent devices that communicate with ZeroMQ events internally. This system runs in a containerised environment managed by Kubernetes (k8s). k8s provides primitive resource types for the abstract management of compute, network and storage, as well as a comprehensive set of APIs for customising all aspects of cluster behaviour. These capabilities are encapsulated in a framework (Operator SDK) which enables the creation of higher order resources types assembled out of the k8s primitives (\verb|Pods|, \verb|Services|, \verb|PersistentVolumes|), so that abstract resources can be managed as first class citizens within k8s. These methods of resource assembly and management have proven useful for reconciling some of the differences between the TANGO world and that of Cloud Native computing, where the use of Custom Resource Definitions (CRD) (i.e., Device Server and DatabaseDS) and a supporting Operator developed in the k8s framework has given rise to better usage of TANGO-controls in k8s.
