The popularity of Virtual SAN is growing daily. Server admins are finally free to aggregate storage in their servers to create a shared storage system that scales with their compute needs. The underlying key to making it all work is networking. All Virtual SAN data flows through it, and correct selection and configuration of networking components will mean the difference between disruptive success or dramatic failure. This session will give deep insight in the do's and don'ts of Virtual SAN networking. Best practices for physical and virtual switch configuration and performance testing will be discussed. Virtual SAN 5.5 and 6.0 will be covered, and the networking differences discussed. Methods of troubleshooting network issues will be covered. For those configuring a Virtual SAN network for the first time, for labs or enterprise scale, this session is a must-see.

VMworld 2015: Advanced SQL Server on vSphereVMworld
Microsoft SQL Server is one of the most widely deployed “apps” in the market today and is used as the database layer for a myriad of applications, ranging from departmental content repositories to large enterprise OLTP systems. Typical SQL Server workloads are somewhat trivial to virtualize; however, business critical SQL Servers require careful planning to satisfy performance, high availability, and disaster recovery requirements. It is the design of these business critical databases that will be the focus of this breakout session. You will learn how build high-performance SQL Server virtual machines through proper resource allocation, database file management, and use of all-flash storage like XtremIO. You will also learn how to protect these critical systems using a combination of SQL Server and vSphere high availability features. For example, did you know you can vMotion shared-disk Windows Failover Cluster nodes? You can in vSphere 6! Finally, you will learn techniques for rapid deployment, backup, and recovery of SQL Server virtual machines using an all-flash array.
Not content to simply describe the Virtual Volume (VVOL) framework, this session instead examines practical use cases: How different configurations and workloads benefit from VVOLs. Learn how Storage Policy Based Management (SPBM) couples with VVOLs to provide VM configuration options not previously available. We demonstrate a handful of real-life scenarios, specifically covering how VVOLs benefits oversubscribed systems, disaster recovery preparation and multi-tenant requirements for customers. Specific configuration options and constraints are covered in detail, including how they work with underlying storage.
Industry leaders Cisco, NetApp, VMware and Symantec have teamed up to develop a best practice framework and performance benchmark based on the VMware vSphere® Storage APIs - Data Protection (VADP). The test configuration uses the popular NetApp FlexPod environment, and the result proves that you can easily protect over 4 TB of virtual machine data per hour. And improved backup performance creates more reliable backups, shorter backup windows and less impact on the vSphere infrastructure.
In this session, we will show how these performance numbers can be easily obtained with minimal hardware and a small budget. In addition to backup performance, we will also discuss restore performance considerations.
Key topics include:
• How to select the correct hardware for the best ROI
• Strategies for minimizing backup impact and maximizing backup throughput
• Performance characteristics of VADP
• SAN or NBD (network) transports: which is recommended?
• Configurations for the fastest possible restores

A la découverte du standard OpenStack et de ses APIs
OpenStack est la brique logicielle open source sur laquelle s'appuie OVHcloud pour proposer son offre de Public Cloud (compute, storage, network, …). OpenStack permet l’administration complète des ressources à travers une API particulièrement riche. Raison pour laquelle OVHcloud en donne un accès exhaustif aux utilisateurs de son Public Cloud, nombreux à manipuler leurs ressources en lignes de commande.
Au fil de ce meetup, nous poserons les bases de l’architecture et du fonctionnement d’OpenStack et de ses différents composants. Nous parlerons ensuite du fonctionnement des APIs OpenStack, éléments clés pour interagir avec OpenStack. Nous finirons par quelques usages de ces APIs au travers d’outils connus comme Terraform, qui permettront de mettre en évidence l’importance de proposer un standard dans l’univers du Public Cloud.
Migrer 3 millions de sites sans maitriser leur code source ? Impossible mais ...OVHcloud
Il y a deux ans, nous apprenions notre nouvelle mission : migrer les 3 millions de sites web hébergés dans notre datacentre de Paris. Sans en maitriser le code source, les migrer sans impact nous semblait totalement irréaliste.
18 mois plus tard, c'est terminé ! Pour y arriver, nous avons du configurer des proxy SQL, des tunnels réseau, migrer des IP entre nos datacentres, livrer des milliers de serveurs, bosser durant des dizaines de nuits, mais aussi s'organiser entre plusieurs équipes qui n'ont pas l'habitude de travailler ensemble. Quels sont les soucis technique et humains que nous avons rencontrés, et comment les avons nous résolu ? Retour d'expérience sur l'une des plus grosse migration que le web ai connu !
Le machine learning et l’IA sont des buzzwords qui font maintenant partie de notre quotidien. Pourtant, rares sont les projets qui osent inclure du ML dans leur cycle de vie.
Les raisons sont multiples :
- Inquiétudes sur un niveau d’expertise trop limité en DataScience
- Difficultés d’apprécier à l’avance le gap entre difficulté de mise en place et retour sur investissement
- Inquiétudes sur la pérennité des efforts investis : (dérive des modèles entrainés)
- Peur de s’engager dans un effort trop important de maintenance sur le long terme
Bien que fondées, ces raisons n’ont plus lieu d’être après la mise en place de procédés d’industrialisation spécifiques à ce genre de problème.
Venez découvrir comment nous avons fait converger les compétences des datascientists et des devops afin de créer une plate-forme de machine learning simple, scalable et accessible aux non-experts. De l’analyse des données à la mise en production de modèles nous verrons comment industrialiser les procédés d’apprentissage automatique sans le moindre effort.

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.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

However, as technological advancements continue to push the boundaries of innovation, alternative operating systems have emerged, challenging the status quo and offering users a fresh perspective on computing.
One such alternative that has garnered significant attention and acclaim is Nitrux Linux 3.5.0, a sleek, powerful, and user-friendly Linux distribution that promises to redefine the way we interact with our devices. With its focus on performance, security, and customization, Nitrux Linux presents a compelling case for those seeking to break free from the constraints of proprietary software and embrace the freedom and flexibility of open-source computing.
In his public lecture, Christian Timmerer provides insights into the fascinating history of video streaming, starting from its humble beginnings before YouTube to the groundbreaking technologies that now dominate platforms like Netflix and ORF ON. Timmerer also presents provocative contributions of his own that have significantly influenced the industry. He concludes by looking at future challenges and invites the audience to join in a discussion.

The Metaverse and AI: how can decision-makers harness the Metaverse for their...Jen Stirrup
The Metaverse is popularized in science fiction, and now it is becoming closer to being a part of our daily lives through the use of social media and shopping companies. How can businesses survive in a world where Artificial Intelligence is becoming the present as well as the future of technology, and how does the Metaverse fit into business strategy when futurist ideas are developing into reality at accelerated rates? How do we do this when our data isn't up to scratch? How can we move towards success with our data so we are set up for the Metaverse when it arrives?
How can you help your company evolve, adapt, and succeed using Artificial Intelligence and the Metaverse to stay ahead of the competition? What are the potential issues, complications, and benefits that these technologies could bring to us and our organizations? In this session, Jen Stirrup will explain how to start thinking about these technologies as an organisation.

Architecture principle / roles description
Each database cluster is composed of different items :
• Load balancing : based on replicated appliances and HAProxy, they balance the network trafic to your nodes
(primary and replicas). You can use different ports for Read-Only and Read-Write, or use the same.
• Primary node : based on 1 x dedicated host (single-tenant), it accepts Read-Write operations. If you configure
your application to use the same port for Read and Write operations, Primary Node will also accept Read-Only
operations.
• Replicas nodes : based on n x dedicated host (single-tenant), they accept Read-Only operations. They allow you
horizontal scaling. By default, a cluster is composed of 1 x Replica Node.
• Backup node : based on 1 x dedicated host (single-tenant), it will NOT accept Read nor Write operations. It
replicates your data and is used for non-degradating backuping. Backups are performed on this dedicated node
instead of the production one.
• Cluster Storage : based on local SSD storage, with RAID10 (replicated storage). They will store your operational
data. Backups are stored in OVH filer storage
• Backup storage : based on 2 x OVH filer storage, they store your backups and allow you to restore backups.

Architecture principles / roles discovery
Load Balancing
RW traffic:
Are you
primary?
Relational database clustering implies specific roles.
To counter outages scenarios, such as a “Primary Node
down”, we implemented high-availability templates :
• Automatic role discovery
– Primary node for RW traffic
– Secondaries nodes for RO traffic
– No traffic for backup node
– … everything made with Quorum (wikipedia explanation)
• Fast & Continuous discovery
– Probe every 30 seconds

Automatic and on-demand backups
Your data, safe and sound
Each Day
Your cluster is
backuped, replicated
multiple times.
Backups are performed
on dedicated node
(the backuper) to
avoid noise on
production. We keep
them 3 rolling months.
01
Daily
Right when
you want
You can always ask for
a backup when you
want, like for example
before a major update
in your app.
Backup are performed
on dedicated node
(the backuper) to avoid
noise on production.
02
On Demand
03
Whenever
Log files are also
backuped. This way
you can go back in

Restore
You are able to request backups restoration when you want !
• No downtime
– Restore on a dedicated host
• Close to the hour
– Choose between your backups or specify a date+hour (PITR)
• Pay per restore
– You select a cloud instance flavor, and you will pay your restore hourly.

Backups/Restore : sum-up
What is done Perimeter included
Data daily auto backups We perform daily physical ZFS snapshots (we don’t use pg_dump). Datafiles on filesystem
Data “on demand” backups You can perform “on demand” backup through API and control panel, when you want Same as daily backups
Data backups process
Each backup is made on the “backuper node”, isolated from the production.
No impacts on your performances. We stop postgresql process on this node during this time.
N/A
Data backups retention By default, we keep all your backups for 3 rolling months. Daily backups
Data backups replication We keep data backups on 2 different and autonomous spaces, called filers storage Daily + “On demand” backups
Data backups integrity
We perform backup on a dedicated host (the backuper node) and we stop postgresql process
during this process. Integrity is preserved. We don’t perform integrity checks after (but soon)
Daily + “On demand” backups
WAL backup/retention We perform continuous backups of WAL, limited to 3 rolling month, on Object Storage. All WAL from primary node
Logs/Metrics retention
We store logs for 1 rolling month, metrics for 1 year (soon), and give you observability tools to
access them.
Logs : PostgreSQL process
Metrics : all nodes
PITR feature We keep all your WAL allowing you PITR, see after. N/A
Restore a data backup
When you ask for a restore, you can request a backup ID or a specific day+hour.
If you request a backup ID, we will spawn an instance with your snapshot, in read-only, and
provide you and IP and ports to connect. You pay the same prices as OVH Public Cloud.
You are then free to do what you want (dump+restore on production, …)
If you ask for a specific day+hour, we will use PITR feature.

Offical documentation : https://www.postgresql.org/docs/11/pgbench.html
• Clusters ordered in region West-Europe (France) with PostgreSQL 11
• Client ordered in the same region (OVH Public Cloud B2-60), Debian 9.
• We simulate different amount of client connections : 32, 64, 128, 256, 512.
• Via the script, pgbench is launched 3 times on each cluster :
1. Read-write bench (warmup): 1800 seconds, fillfactor 100, scale_factor 2000
2. Read-write bench (production) : 1800 seconds, fillfactor 100, scale_factor 2000
3. Read-only bench : 1800 seconds, fillfactor 100, scale_factor 2000
• It creates approximately 30GB of data on disk
