Managing a data center poses multifaceted challenges, with monitoring emerging as a pivotal aspect for ensuring stability and service quality assurance. Since the first implementation of a monitoring system in the Green IT Cube data center at GSI in 2016, comprising RRDtool and Ganglia, ongoing efforts have been dedicated to enhancing monitoring capabilities. The initial system's tight...
The INFN Information System project was established in 2001 with the aim of computerizing and standardizing the administrative processes of the Institute and gradually moving towards dematerialization and digitization of documents. During these two decades the aim of the project has been accomplished by a series of web applications (what we call sysinfo apps) serving INFN researchers,...
In the last 20 years, CERN’s Live Streaming service [1] has been a pivotal communication tool connecting CERN users and the High Energy Physics (HEP) community in real time. From its initial stages, employing Real Media technologies and Flash, to its present state, integrating cutting-edge technologies like HTTP Live Streaming (HLS), the service has been instrumental in fostering global...
A robust computing infrastructure is essential for the success of scientific collaborations. However, smaller collaborations often lack the resources to establish and maintain such an infrastructure, resulting in a fragmented analysis environment with varying solutions for different members. This fragmentation can lead to inefficiencies, hinder reproducibility, and create collaboration...
After a brief introduction on the Muon Alignment optical system and the dataflow for the optical lines, I will illustrate our infrastructure which is based on Micro-services in Java (mainly for the access to Oracle DB) and C++ (for the alignment algorithm itself) and deployed on a dedicated K8s cluster at CERN.
The end of life of CentOS 7 accelerates the transition from VOMS proxies to OAuth tokens as the means to convey authorization information on a Grid/Cloud infrastructure. As a consequence, the VOMS and VOMS-Admin services will be abandoned in favor of INDIGO-IAM (or equivalent products) for the management of VO membership and the issuance of proxies and tokens.
In this contribution we present...
In recent times, experiment analysis frameworks and physics data formats of the LHC experiments have been evolving in a direction that makes interactive analysis with short turnaround times much more feasible. In parallel, many sites have set up Analysis Facilities to provide users with tools and interfaces to computing and storage that are optimised for interactive analysis. At CERN we...
More than 2000 daily users use the remote desktop access service from outside CERN, supporting remote work capabilities in the organization.
To improve the operation of the service, a new self-service solution for remote desktop access was launched in 2023 that empower users to manage their devices set up for remote access. The solution includes parallelization, caching, and automated...
Based on extensive experience in system maintenance and advanced artificial intelligence technology, we have designed the IHEP computing platform's intelligent operations and maintenance system. Its primary goal is to ensure optimal utilization and efficiency of computing resources.
This system automatically detects user jobs that cause anomalies in computing services and dynamically adjusts...
Nix is a tool for packaging software with a heavy focus on reproducibility. NixOS is a Linux distribution based on the Nix package manager.
This talk is a series of demonstrations of what Nix and NixOS can do for you. Depending on the time, here is what I'm going to show off:
- A presentation of the Nix model
- Its advantages in terms of supply-chain security
- Building minimal,...
An important aspect of IT security is the management, controlled sharing and storage of sensitive data such as passwords or API tokens. In this talk we present how HashiCorp Vault is used at DESY to address this challenge and how the system is integrated into workflows like certificate management and the existing IT infrastructure such as Puppet and GitLab. As secret management is a critical...
