An Update on the CERN Journey from Bare Metal to Orchestrated Containerization for Controls
/ Oulevey, Thomas (CERN) ; Copy, Brice (CERN) ; Locci, Frank (CERN) ; Page, Stephen (CERN) ; Rocha, R (CERN) ; Roderick, Chris (CERN) ; Vanden Eynden, Marc (CERN) ; de Martel, Jean-Baptiste (CERN)
At CERN, work has been undertaken since 2019 to transition from running Accelerator controls software on bare metal to running in an orchestrated, containerized environment. This will allow engineers to optimise infrastructure cost, to improve disaster recovery and business continuity, and to streamline DevOps practices along with better security. [...]

Improving CERN’s Web-based Rapid Application Platform
/ Galatas, Epameinondas (CERN) ; Deghaye, Stephane (CERN) ; Raban, Jakub (CERN) ; Roderick, Chris (CERN) ; Saxena, Dinika (CERN) ; Solomou, Andreas (CERN)
The Web-based Rapid Application Platform (WRAP) aims to provide a centralized, zero-code, drag-n-drop means of GUI creation*. It was developed at CERN to address the high maintenance cost of supporting multiple evolving GUI-technologies and minimising duplication of effort by those developing different GUI applications. [...]

Micro Frontends - a New Migration Process for Monolithic Web Applications
/ Asko, Anti (CERN) ; Deghaye, Stephane (CERN) ; Galatas, Epameinondas (CERN) ; Kustra, Ajob (CERN) ; Roderick, Chris (CERN) ; Urbaniec, Bartlomiej (CERN)
Numerous standalone web applications have been developed over the last 10 years to support the configuration and operation of the CERN accelerator complex. These applications have different levels of complexity, but they all support hundreds of users for essential activities. [...]

WRAP - A Web-Based Rapid Application Development Framework for CERN’s Controls Infrastructure
/ Galatas, Epameinondas (CERN) ; Asko, Anti (CERN) ; Matli, Emanuele (CERN) ; Roderick, Chris (CERN)
To ensure stable operation of CERN’s accelerator complex, many Devices need to be controlled. To meet this need, over 500 custom Graphical User Interfaces (GUI) have been developed using Java Swing, Java FX, NetBeans, Eclipse SWT, etc. [...]

Accelerator fault tracking at CERN
/ Roderick, Chris (CERN) ; Burdzanowski, Lukasz (CERN) ; Martin Anido, Daniel (CERN) ; Pade, Steffen (CERN) ; Wilk, Pawel (CERN)
CERN’s Accelerator Fault Tracking (AFT) system aims to facilitate answering questions like: “Why are we not doing physics when we should be?” and “What can we do to increase machine availability?” People have tracked faults for many years, using numerous, diverse, distributed and un-related systems. As a result, and despite a lot of effort, it has been difficult to get a clear and consistent overview of what is going on, where the problems are, how long they last for, and what is the impact. [...]

CERN Controls Configuration Service - a challenge in usability

Complex control systems often require complex tools to facilitate daily operations in a way that assures the highest possible availability. Such a situation poses an engineering challenge, for which system complexity needs to be tamed in a way that everyday use becomes intuitive and efficient. [...]

The Renovation of the CERN Controls Configuration Service
/ Burdzanowski, Lukasz (CERN) ; Roderick, Chris (CERN)
The Controls Configuration Service (CCS) is a key component in CERN's data driven accelerator Control System. Based around a central database, the service also provides a range of client APIs and user interfaces - enabling configuration of controls for CERN's accelerator complex. The service has existed for 35 years (29 based on Oracle DBMS). There has been substantial evolution of the CCS over time to cater for changing requirements and technology advances. Inevitably this has led to increases in CCS complexity and an accumulation of technical debt. These two aspects combined have a negative impact on the flexibility and maintainability of the CCS, leading to a potential bottleneck for Control System evolution. This paper describes on-going renovation efforts (started mid-2014) to tackle the aforementioned issues, whilst ensuring overall system stability. In particular, this paper covers architectural changes, the agile development process in place - bringing users close to the development cycle, and the deterministic approach used to treat technical debt. Collectively these efforts are leading towards a successful renovation of a core element of the Control System..
