Current network service trends and requirements are increasing the pressure on flexibility and reliability that must be provided by the virtual computer and network systems that support them. It is the case of Open-Stack-based systems, whose incorporation to current network infrastructures is constantly increasing, including the particular case of edge/branch network systems. The nature of such systems emphasizes the importance of keeping close-to-optimum resource allocations, so resources are not wasted and (monetary and operative) cost is reduced as much as possible. Obviously, the main characteristics of these requirements, namely the fast detection and adaptation to environment changes, are beyond human abilities, so the operation must be automated. In this paper we discuss how to resolve such problem by using the Autonomic Resource Control Architecture (ARCA) to control a multi-domain OpenStack deployment, also introducing the in-lab deployment we are building to validate our solution.
