Architecting the OpenSearch service at CERN / Papadopoulos, Sokratis (CERN) ; Saiz, Pablo (CERN) ; Schwickerath, Ulrich (CERN) ; Kleszcz, Emil (CERN)
The centralised Elasticsearch service has been running at CERN since 2016, providing the search and analytics engine for numerous CERN users. The service has been based on the open-source version of Elasticsearch, surrounded by a set of external open-source plugins offering security, multitenancy, extra visualization types, and more. [...]

Data preservation in high energy physics / DPHEP Collaboration
Data preservation is a mandatory specification for any present and future experimental facility and it is a cost-effective way of doing fundamental research by exploiting unique data sets in the light of the continuously increasing theoretical understanding. This document summarizes the status of data preservation in high energy physics. [...]

Anomaly Detection for the Centralised Elasticsearch Service at CERN / Andersson, Jennifer R (Uppsala U. (main)) ; Moya, Jose Alonso (Carlos III U., Madrid) ; Schwickerath, Ulrich (CERN)
For several years CERN has been offering a centralised service for Elasticsearch, a popular distributed system for search and analytics of user provided data. The service offered by CERN IT is better described as a service of services, delivering centrally managed and maintained Elasticsearch instances to CERN users who have a justified need for it. [...]

Large Elasticsearch cluster management / Saiz, Pablo ; Schwickerath, Ulrich
The Centralised Elasticsearch Service at CERN runs the infrastructure to provide Elasticsearch clusters for more than 100 different use cases.This contribution presents how the infrastructure is managed, covering the resource distribution, instance creation, cluster monitoring and user support. The contribution will present the components that have been identified as critical in order to share resources and minimise the amount of clusters and machines needed to run the service. [...]

Securing and sharing Elasticsearch resources with Read-onlyREST / Schwickerath, Ulrich (CERN) ; Saiz, Pablo (CERN) ; Toteva, Zhechka (CERN)
In early 2016 CERN IT created a new project to consolidate and centralise Elasticsearch instances across the site, with the aim to offer a production quality new IT services to experiments and departments. We present the solutions we adapted for securing the system using open source only tools, which allows us to consolidate up to 20 different use cases on a single Elasticsearch cluster..

The machine/job features mechanism / Alef, M (KIT, Karlsruhe) ; Cass, T (CERN) ; Keijser, J J (NIKHEF, Amsterdam) ; McNab, A (Manchester U.) ; Roiser, S (CERN) ; Schwickerath, U (CERN) ; Sfiligoi, I (Fermilab)
Within the HEPiX virtualization group and the Worldwide LHC Computing Grid’s Machine/Job Features Task Force, a mechanism has been developed which provides access to detailed information about the current host and the current job to the job itself. This allows user payloads to access meta information, independent of the current batch system or virtual machine model. [...]

Benchmarking and accounting for the (private) cloud / Belleman, J (CERN) ; Schwickerath, U (CERN)
During the past two years large parts of the CERN batch farm have been moved to virtual machines running on the CERN internal cloud. During this process a large fraction of the resources, which had previously been used as physical batch worker nodes, were converted into hypervisors. [...]
