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. [...]

CERN Open Data / Saiz, Pablo (speaker) (CERN)
The goal of CERN Open Data is to make experiment data available to the general public in a way that can be easily used and to preserved for the long-term. This comes with a set of challenges: * The most important is to make sure that the data follows the FAIR principles: it should be Findable, Accessible, Interoperable, and Reusable. * That also includes the the long preservation of the data, and ensuring that it is immutable. * On top of that, the volume of data can also be challenging.

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. [...]

Achieving metric oriented load balancing / Canilho, Paulo (CERN) ; Reguero, Ignacio (CERN) ; Saiz, Pablo (CERN)
The Load Balance Service at CERN handles more than 500 aliases, distributed over more than 2000 nodes. After being in production for more than fifteen years, it has been going through a major redesign over the last two years. [...]

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..

Concurrent adaptive load balancing at CERN / Canilho, Paulo (CERN) ; Reguero, Ignacio (CERN) ; Saiz, Pablo (CERN)
CERN is using an increasing number of DNS based load balanced aliases (currently over 700). This article explains the Go based concurrent implementation of the Load Balancing Service, both the client (lbclient) and the server (lbd). [...]

Interoperating AliEn and ARC for a Distributed Tier1 in the Nordic Countries / Gros, Philippe (Lund U.) ; Gregersen, Anders Rhod (Aalborg U.) ; Lindemann, Jonas (Lund U. (main)) ; Saiz, Pablo (CERN) ; Zarochentsev, Andrey (St. Petersburg State U.)
To reach its large computing needs, the ALICE experiment at CERN has developed its own middleware called AliEn, centralised and relying on pilot jobs. One of its strength is the automatic installation of the required packages. [...]
