Most of my apps could be easily done with a database and several serverless functions! It wasn’t the first time I’d got that question… Being, above all, a web developer, I can definitely relate. Kubernetes is a wonderful product – you can install complicated web architectures with a click – but what about the database + (...)

Alerting based on IPMI data collection https://www.ovh.com/fr/blog/alerting-based-on-ipmi-data-collection/ https://www.ovh.com/fr/blog/alerting-based-on-ipmi-data-collection/#respond Fri, 10 May 2019 13:56:55 +0000 https://blog.ovh.com/fr/blog/?p=14974 The problem to solve… How to continuously monitor the health of all OVH servers, without any impact on their performance, and no intrusion on the operating systems running on them – this was the issue to address. The end goal of this data collection is to allow us to detect and forecast potential hardware failure, in order to improve the quality of service delivered to our customers. We began by splitting the problem into four general steps: Data collection Data storage Data analytics Visualisation/actions Data collection How did we collect massive amounts of server health data, in a non-intrusive way, within (...)

OVH Private Cloud and HashiCorp Terraform – Part 1 https://www.ovh.com/fr/blog/private_cloud_and_hashicorp_terraform_part1/ https://www.ovh.com/fr/blog/private_cloud_and_hashicorp_terraform_part1/#respond Fri, 03 May 2019 08:59:46 +0000 https://blog.ovh.com/fr/blog/?p=15407 When discussing the concepts of DevOps and Infrastructure-as-a-Code, the tools developed by HashiCorp quickly come up. With Terraform, HashiCorp offers a simple way to automate infrastructure provisioning in both public clouds and on-premises. Terraform has a long history of deploying and managing OVH’s Public Cloud resources. For example, you can find a complete guide on GitHub. In this article, we will focus on using Terraform to interact with another OVH solution: Private Cloud. Private Cloud enables customers to benefit from a VMware vSphere infrastructure, hosted and managed by OVH. Terraform lets you automate the creation of resources and their life cycle. (...)

Prescience: Introducing OVH’s Machine Learning Platform https://www.ovh.com/fr/blog/prescience-introducing-ovhs-machine-learning-platform/ https://www.ovh.com/fr/blog/prescience-introducing-ovhs-machine-learning-platform/#respond Fri, 26 Apr 2019 13:21:01 +0000 https://blog.ovh.com/fr/blog/?p=15243 Machine Learning projects are becoming an increasingly important component of today’s search for more efficient and complex industrial processes. OVH Prescience is a Machine Learning platform that aims to ease the conception, deployment and serving of models in an industrial context. The system manages Machine Learning pipelines, from data ingestion to model monitoring. This involves the automation of data preprocessing, model selection, evaluation, and deployment within a scalable platform. Prescience supports various kinds of problems, such as regression, classification, time series forecasting, and soon, anomaly detection. Problem resolution is handled through the use of both traditional ML models and neural (...)

Ceux qui l’ont déjà fait, ou qui doivent le faire régulièrement, connaissent les difficultés de ce type d’opération. Pour vulgariser à l’extrême, cette opération nécessite généralement six étapes : achat et configuration de l’infrastructure de destination ; test de cette nouvelle infrastructure en important les données et le code du site web ; fermeture ou mise en lecture seule du site web pour éviter que des données soient enregistrées sur l’ancienne infrastructure durant la migration ; déploiement du code sur la nouvelle infrastructure, import des données dans les nouvelles bases de données ; modification du (...)

Web hosting — why we decided to migrate three million websites https://www.ovh.com/fr/blog/web-hosting-why-we-decided-to-migrate-three-million-websites/ https://www.ovh.com/fr/blog/web-hosting-why-we-decided-to-migrate-three-million-websites/#respond Fri, 19 Apr 2019 11:46:27 +0000 https://blog.ovh.com/fr/blog/?p=15383 Have you migrated a website before? If you have, or will need to migrate websites regularly, you’ll be familiar with the difficulties associated with this kind of operation. To put in the most basic terms, this operation usually involves six steps: purchasing and configuring the destination infrastructure testing the new infrastructure by importing data and website code shutting down the website, or putting it in read-only mode to stop the data from being saved on the old infrastructure during the migration process deploying code on the new infrastructure, and importing data into the new databases modifying the source code to (...)

Deploying game servers with Agones on OVH Managed Kubernetes https://www.ovh.com/fr/blog/deploying-game-servers-with-agones-on-ovh-managed-kubernetes/ https://www.ovh.com/fr/blog/deploying-game-servers-with-agones-on-ovh-managed-kubernetes/#respond Fri, 12 Apr 2019 10:01:44 +0000 https://blog.ovh.com/fr/blog/?p=15322 One of the key advantages of usisng Kubernetes is the formidable ecosystem around it. From Rancher to Istio, from Rook to Fission, from gVisor to KubeDB, the Kubernetes ecosystem is rich, vibrant and ever-growing. We are getting to the point where for most deployment needs we can say there is a K8s-based open-source project for that. One of the latests additions to this ecosystem is the Agones project, an open-source, multiplayer, dedicated game-server hosting built on Kubernetes, developed by Google in collaboration with Ubisoft. The project was announced in March, and has already made quite a bit of noise… In (...)

In fewer than 18 months, we doubled the number of employees from twelve hundred to twenty-five hundred. I don’t recommend scaling this fast!  OVH is a digital company in that we use software to deliver the service ordered by the customer. Like other companies, we serve our customers in many ways, but the actions of our employees do not have the same why. Toward (...)
