- Criteo SRE Tech Talks
Criteo Labs is excited to bring you our next SRE meetup in our Paris office. We have a great line-up of talks from both our Criteo R&D Engineers and our guest speaker. ⌚ Agenda : 6:30 pm : welcome 7:00 pm : talks 9:00 pm : networking _______________________________________________________________________________________ Talks : 🎤 Christophe Nasarre-Soulier, Staff Software Dev Eng Actions at Criteo 📃 A day of investigations at Criteo In our team, a large part of our time is dedicated to solve issues met by Criteo .NET applications. Come and discover which tool to use from Process Explorer to WinDBG, including our own self-built tools in your own investigations. 🎤 Olivier Mallassi, Principal Architect at Murex 📃 Legacy is an asset that can also follow "rules of big" When we hear about "Legacy" we, as tech guys, often run away to look for green-field projects where we can express all our creativity. It is true that legacy system is not an easy place to work in and you likely have to adapt and play with the overall system of constraints, and at some point break some of them. Ones can see this ability to overcome constraints as greater creativity. In fact, whatever you see it, Legacy System is an asset that can and must evolve and follow best practices. The idea here is to share some patterns and technologies (data, stream, cloud) we use on the MX.III platform to unleash our monolith, and follow the state-of-the-art rules. 🎤 Pierre Mavro, Staff SRE Lead at Criteo 📃Kubernetes at NoSQL Managing stateful applications is not an easy task. Getting them working at scale on +3500 servers world wide starts to be very time consuming. We'll talk about challenges we've been facing when moving from a full configuration manager (chef) solution to a mixed solution with a scheduler (Kubernetes). We'll also talk about the pitfalls to avoid when switching to a scheduler for stateful apps. 🎤 Pierre Souchay, Senior Staff SRE Lead at Criteo 📃Discovery Scaling Challenges & Opportunities In the last year, Criteo has been performing Critical changes to Consul, the heart of current Discovery at Criteo to address performance and robustness. We will expose the changes we made and future directions towards safer APIs and new incoming features.
- Criteo Full-Stack Tech Talks
- Criteo Labs Infrastructure Tech Talks
Criteo Labs is excited to bring you our next infrastructure meetup in our Paris office. We have a great line-up of talks from both our Criteo R&D Engineers and our guest speaker. Agenda: 18:00 – 19:00 : Welcome 19:00 – 21:00 : Meetup 21:00 - 22:00 : Networking Session Talks Line-up: #1: Jean Marie Verdun, CEO, Horizon Computing Solutions Corp Open hardware and datacenters: evolution, revolution or flop? During this talk, we will discuss the main technological evolutions of Open Compute, Open Power and RISC-V projects, most of focus on developments associated with data center applications. We will discuss the barriers to adoption that can make these projects flops, evolutions or revolutions. #2: Dan Forest-Barbier, Staff DevOps Engineer, Criteo SONiC at Criteo: we love hedgehogs, and you should too! We run data-center networks at scale, and this requires sourcing equipment from different brands. This equipment cannot run without the associated software: different for each brand, often proprietary, costly, quirky, possibly buggy, engineered to support a million features we do not use. Over the past year we worked on bring an Free and Open Source Software stack in to manage the bulk of this equipment; and we chose Microsoft Azure's SONiC project. We will provide some context to our adventures and go over the benefits in the first ~5min. The remaining ~15min. will be about the more meaty (or tofu-y) details of our experience. Finally, we will share our vision around alternative network software and hardware. #3: Alexandre Cortyl, Senior Data Analyst, Criteo & Pierre-Yves Verdon, Senior Hosting Engineer, Criteo Capacity planning at scale. In less than 10 years, Criteo's growth has translated into vertiginous changes: from 1 to 16 data centers, from 100 to 35,000 servers, from a few GBs to 5Tb / s on the WAN ... Predicting on this scale the needs of this platform which now displays more than 5 billion banners is a real challenge. This presentation will present our feedback on the capacity planning effort. Forecast traffic, load tests, budget management, purchases, projects ... Between infrastructure, purchasing, development, business intelligence and automation, capacity planning is the keystone of growth. See you around.

- Criteo Labs Infrastructure Tech Talk
Criteo is excited to bring you our next infrastructure meetup in our Paris office. By joining hands with Dailymotion and Leboncoin, we have a great line-up of talks from both our Criteo engineers and our guest speakers. Agenda: 18:00 - Arrival 18:30 - Welcome Speech (Matthieu Blumberg - Engineering Director Infrastructure Operations, Criteo R&D) 18:45 - Talks Begin 21:00 - Networking Session Talks Line-up: #1: Gilles Vieira, Senior Video Workflow Architect, Dailymotion Hardware-assisted transcoding @ Dailymotion Abstract: Video transcoding is a real beast: in addition to being hard to get right, it’s also very CPU-intensive, and probably the most important daily subject here for us in Dailymotion’s video architecture team. A while ago, we asked ourselves this: what if we could save time and power while still retaining a decent output quality for the massive amount of transcodings we perform every day? Sounds appealing right? If you want to know more, then fasten your seatbelt and read-on about hardware-assisted video transcoding. #2: Mohamed Benazza, Staff Ops Lead, Criteo R&D & Nicolas Perez, Staff Ops Lead, Criteo R&D The Request For Proposal (RFP) Challenge Since I came six years ago, we went from 6 Datacenters to 16 today. The opening of 2 new Datacenters per year has required the internal development to have a robust document with a process, strong rules, fundamental questions and relevant agenda: the Criteo Hosting Datacenter Request For Proposal (RFP). It is the best way we found to ask Datacenter “experts” to solve our rich problem of growth: I mean more and more power everywhere. Managing an RFP is the longest but the most interesting and the hardest but exciting project at Criteo for a Hosting Engineer. During this meetup, we will present you, in details, how we look for the best DC for Criteo and how we manage our RFP whatever is the city, the country or the continent. We are Datacenter hunters, and it is just the beginning. #3: Félix Cantournet, SRE, Leboncoin & Xavier Krantz, SRE Lead, Leboncoin New bare-metal provisioning setup built around Collins @ Leboncoin We'd like to talk about our new bare-metal provisioning setup built around Collins (which is an opensource CMDB/IPAM project from Tumblr) and the workflows associated. See you around.
