“…The containerization, a hallmark of modern software deployment, carries with it a host of benefits [12]. The orchestration of containers, once a cumbersome task, is streamlined through orchestration systems such as Kubernetes [13,14], an industryproven container orchestration platform [15,16]. Containerization of software and container orchestration allow the use of available computational resources as a unified resource pool while different versions of software, down to the OS distribution specific libraries, can coexist within a single network host.…”

The CMS data acquisition (DAQ) is implemented as a service-oriented architecture where DAQ applications, as well as general applications such as monitoring and error reporting, are run as self-contained services. The task of deployment and operation of services is achieved by using several heterogeneous facilities, custom configuration data and scripts in several languages. In this work, we restructure the existing system into a homogeneous, scalable cloud architecture adopting a uniform paradigm, where all applications are orchestrated in a uniform environment with standardized facilities. In this new paradigm DAQ applications are organized as groups of containers and the required software is packaged into container images. Automation of all aspects of coordinating and managing containers is provided by the Kubernetes environment, where a set of physical and virtual machines is unified in a single pool of compute resources. We demonstrate that a container-based cloud architecture provides an acrossthe-board solution that can be applied for DAQ in CMS. We show strengths and advantages of running DAQ applications in a container infrastructure as compared to a traditional application model.

“…Control systems evolve from hierarchical, controller-centric structures toward a flatter, network-centric architecture, enhancing interconnectivity and facilitating communication with cloud services and edge devices [4,16]. These advancements have been leveraged for fault tolerance-employing backup DCNs in the cloud or orchestrators to recover from DCN failures [7,9]. To our knowledge, the NRP FD algorithm is the first effort to reduce the CAP theorem's [6] availability tradeoff while preserving consistency in DCN redundancy scenarios [10].…”

A potential problem that may arise in the domain of distributed control systems is the existence of more than one primary controller in redundancy plans that may lead to inconsistency. An algorithm called NRP FD is proposed to solve this issue by prioritizing consistency over availability. In this paper, we demonstrate how by using modeling and formal verification, we discovered an issue in NRP FD where we may have two primary controllers at the same time. We then provide a solution to mitigate the identified issue, thereby enhancing the robustness and reliability of such systems.

“…Orchestration systems are another key element for the Real-Time FaaS vision, as they are used to automatically place, deploy, monitor and migrate the packaged software across the infrastructure, behaving as cloud operating systems [13]. Recently, several studies emerged to adapt existing orchestration systems to real-time needs, many of them based on the popular Kubernetes platform [14,15].…”
