In this session, we'll discuss new volume types in Red Hat Gluster Storage. We will talk about erasure codes and storage tiers, and how they can work together. Future directions will also be touched on, including rule based classifiers and data transformations.
You will learn about:
How erasure codes lower the cost of storage.
How to configure and manage an erasure coded volume.
How to tune Gluster and Linux to optimize erasure code performance.
Using erasure codes for archival workloads.
How to utilize an SSD inexpensively as a storage tier.
Gluster's erasure code and storage tiering design.
"Data classification" is an umbrella term covering things: locality-aware data placement, SSD/disk or normal/deduplicated/erasure-coded data tiering, HSM, etc. They share most of the same infrastructure, and so are proposed (for now) as a single feature.
This session will cover performance-related developments in Red Hat Gluster Storage 3 and share best practices for testing, sizing, configuration, and tuning.
Join us to learn about:
Current features in Red Hat Gluster Storage, including 3-way replication, JBOD support, and thin-provisioning.
Features that are in development, including network file system (NFS) support with Ganesha, erasure coding, and cache tiering.
New performance enhancements related to the area of remote directory memory access (RDMA), small-file performance, FUSE caching, and solid state disks (SSD) readiness.

GlusterFS : un file system open source per i big data di oggi e domani - Robe...Codemotion
GlusterFS (www.gluster.org) è un file system distribuito open source, scalabile fino ai petabytes. La presentazione ha lo scopo di mostrare le feature di questo FS e la nostra esperienza, che parte nel 2010 con un cluster da 4TB all'odierno da 30TB: perché è stato scelto, principali features, evoluzione, fallimenti (anche quelli), futuro. Alcune feature: accesso in user-space, protocollo nativo, NFS, SMB . Replicazione, distribuzione, striping dei file o una loro combinazione (e.g: distributed striped replicated). All'interno dell'ecosistema Hadoop può sostituire HDFS.
When you're starting out, staying nimble is paramount. This talk will help you push back infrastructure decisions and keep your options open by storing machine-readable JSON logs, not relational data, and processing them as an event stream to construct your data model on the fly.
The computer science behind a modern disributed data storeJ On The Beach
What we see in the modern data store world is a race between different approaches to achieve a distributed and resilient storage of data. Every application needs a stateful layer which holds the data. There are at least three necessary components which are everything else than trivial to combine, and, of course, even more challenging when heading for an acceptable performance.
Over the past years there has been significant progress in both the science and practical implementations of such data stores. In his talk Max Neunhoeffer will introduce the audience to some of the needed ingredients, address the difficulties of their interplay and show four modern approaches of distributed open-source data stores (ArangoDB, Cassandra, Cockroach and RethinkDB).

Managing your black friday logs Voxxed LuxembourgDavid Pilato
Surveiller une application complexe n'est pas une tâche aisée, mais avec les bons outils, ce n'est pas si sorcier. Néanmoins, des périodes fortes telles que les opérations de type "Black Friday" (Vendredi noir) ou période de Noël peuvent pousser votre application aux limites de ce qu'elle peut supporter, ou pire, la faire crasher. Parce que le système est fortement sollicité, il génère encore davantage de logs qui peuvent également mettre à mal votre système de supervision.
Dans cette session, j'aborderai les bonnes pratiques d'utilisation de la suite Elastic pour centraliser et monitorer vos logs. Je partagerai également avec vous quelques trucs et astuces pour vous aider à passer sans souci vos Vendredis noirs !
Nous verrons :
* Les architectures de monitoring
* Trouver la taille optimale pour l'API _bulk
* Distribuer la charge
* Taille des index et des shards
* Optimiser les E/S disque
Vous ressortirez de la session avec : des bonnes pratiques pour bâtir son système de monitoring avec la suite Elastic, le tuning avancé pour optimiser les performances d'ingestion et de recherche.

The Computer Science Behind a modern Distributed DatabaseArangoDB Database
What we see in the modern data store world is a race between different approaches to achieve a distributed and resilient storage of data. Every application needs a stateful layer which holds the data. There are several different necessary components which are anything but trivial to combine, and, of course, even more challenging when attempting to optimize for performance. Over the past years there has been significant progress in both the science and practical implementations of such data stores. In this talk Dan Larkin-York will introduce the audience to some of the challenges, address the difficulties of their interplay, and cover key approaches taken by some of the industry’s leaders (ArangoDB, Cassandra, CockroachDB, MarkLogic, and more).
Managing your black friday logs - Code EuropeDavid Pilato
Monitoring an entire application is not a simple task, but with the right tools it is not a hard task either. However, events like Black Friday can push your application to the limit, and even cause crashes. As the system is stressed, it generates a lot more logs, which may crash the monitoring system as well. In this talk I will walk through the best practices when using the Elastic Stack to centralize and monitor your logs. I will also share some tricks to help you with the huge increase of traffic typical in Black Fridays.
Topics include:
* monitoring architectures
* optimal bulk size
* distributing the load
* index and shard size
* optimizing disk IO
Takeaway: best practices when building a monitoring system with the Elastic Stack, advanced tuning to optimize and increase event ingestion performance.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

How I ended-up there
BioDec is a micro-SME, once mainly devoted to scientific computing.
Used Gluster (on Debian) since version 3.0.
my typical use case: the multi-TB “shared folder”
“data ponds” for scientific computing apps
run small distributed or replicated Glusters
for years with no problems

The 9th scenario: those looking for a scapegoat.
“Would you be able to maintain and operate Gluster for us?
Would you be able to provide 24x7 1-hour SLAs?”
(No, we can not. Red Hat can, maybe.)
Support is tricky:
What is the long-term-support, rock-solid, stable version of Gluster?
Release pace is accelerating.
Meta-quoting Jeff: “A project is not a product”
Gluster is definitely a project, RHGS is a product (I think).

Lessons from failures
An US-based Gluster consultancy may possibly do OK.
Stop wasting time with requests coming from the US.
Although, it would be nice to have business partners there for referral
Would Red Hat be interested in referrals?
Would it make sense to try to network between Gluster consultants?
some of you are here, tell me what happens to you.

Maximum bandwidth = 200 Mbit (guaranteed)
It is almost OK (to my surprise)
Small volumes, few MB-writes per day from a single FTP entry point.
Varnish and Nginx effectively shield Gluster from the traffic.
Geo-replication issue: by copying a directory tree and then doing a
