Enabling Storage Business Continuity and Disaster Recovery with Ceph distributed storage / Bocchi, Enrico (CERN) ; Lekshmanan, Abhishek (CERN) ; Valverde, Roberto (CERN) ; Goggin, Zachary (CERN)
The Storage Group in the CERN IT Department operates several Ceph storage clusters with an overall capacity exceeding 100 PB. Ceph is a crucial component of the infrastructure delivering IT services to all the users of the Organization as it provides: i) Block storage for OpenStack, ii) CephFS, used as persistent storage by containers (OpenShift and Kubernetes) and as shared filesystems by HPC clusters and iii) S3 object storage for cloud-native applications, monitoring and software distribution across the WLCG.The Ceph infrastructure at CERN is being rationalized and restructured to allow for the implementation of a Business Continuity/Disaster Recovery plan.

ScienceBox 2.0: Evolving the demonstrator package for CERN storage and analysis services / Bocchi, Enrico (CERN) ; Desai, Jimil (CERN) ; Sainz, Samuel Alfageme (SWITCH, Zurich)
With containers being the de-facto standard to package, distribute, and run applications, Helm charts are on the rise for application deployment in managed clusters (e.g., Kubernetes, OpenShift), providing developers and operators with a rich ecosystem of tools to utilize, as well as the means to configure applications and roll changes out in a programmatic way.This paper describes the reboot of the ScienceBox project: The containerized software bundle providing the ability to deploy CERN storage and analysis services on any cloud or local infrastructure. While the service offering provided through ScienceBox remains unchanged, we evolved the original implementation to make use of Helm charts across the entire stack and incorporated a major architectural update to CERNBox, replacing the previous PHP backend with a distributed microservices architecture.

CernVM-FS powered container hub / Bocchi, Enrico (CERN) ; Blomer, Jakob (CERN) ; Mosciatti, Simone (CERN) ; Valenzuela, Andrea (CERN)
Containers became the de-facto standard to package and distribute modern applications and their dependencies. The HEP community demonstrates an increasing interest in such technology, with scientists encapsulating their analysis workflow and code inside a container image. [...]

Preparing for HL-LHC: Increasing the LHCb software publication rate to CVMFS by an order of magnitude / Bocchi, Enrico (CERN) ; Blomer, Jakob (CERN) ; Couturier, Benjamin (CERN) ; Burr, Christopher (CERN) ; van der Ster, Dan (CERN)
In the HEP community, software plays a central role in the operation of experiments’ facilities and for reconstruction jobs, with CVMFS being the service enabling the distribution of software at scale. In view of High Luminosity LHC, CVMFS developers investigated how to improve the publication workflow to support the most demanding use cases. [...]

ScienceBox 2.0: From EOS Storage to Jupyter notebooks in Kubernetes / Bocchi, Enrico (speaker) (CERN)
This contribution reports on the recent revamping of ScienceBox: The container-based stack for science with EOS, CERNBox, and SWAN services for Kubernetes-orchestrated clusters. ScienceBox has been rebuilt from its foundations using modern cloud-native technologies for better service configuration and improved reliability, without compromising on deployment flexibility. Rethinking the whole package also allowed for better alignment of the production services at CERN with their container-based version. Sciencebox has been tested and deployed on a variety of infrastructures, ranging from tiny deployments on developers' laptops to container orchestration platforms on commercial cloud providers with GPU accelerators and 100s of TBs of storage..
