Understanding the anatomy of GPUs using Pokémon https://www.ovh.com/fr/blog/understanding-the-anatomy-of-gpus-using-pokemon/ https://www.ovh.com/fr/blog/understanding-the-anatomy-of-gpus-using-pokemon/#respond Wed, 13 Mar 2019 17:25:32 +0000 https://blog.ovh.com/fr/blog/?p=14482 In the previous episode… In our previous blog post about Deep Learning, we explained that this technology is all about massive parallel matrix computation, and that these computations are simplistic operations: + and x. Fact 1:  GPUs are good for (drum roll)… Once you get that Deep Learning is just massive parallel matrix multiplications and additions, the magic happens. General Purpose Graphic Processing Units (GPGPU) (i.e. GPUs, or variants of GPUs, designed for something other than graphic processing) are perfect for… matrix multiplications and additions ! Perfect isn’t it ? But why ? Let me tell you a little story Fact (...)

How to monitor your Kubernetes Cluster with OVH Observability https://www.ovh.com/fr/blog/how-to-monitor-your-kubernetes-cluster-with-ovh-metrics/ https://www.ovh.com/fr/blog/how-to-monitor-your-kubernetes-cluster-with-ovh-metrics/#respond Fri, 08 Mar 2019 14:33:55 +0000 https://blog.ovh.com/fr/blog/?p=14897 Our colleagues in the K8S team launched the OVH Managed Kubernetes solution last week, in which they manage the Kubernetes master components and spawn your nodes on top of our Public Cloud solution. I will not describe the details of how it works here, but there are already many blog posts about it (here and here, to get you started). In the Prescience team, we have used Kubernetes for more than a year now. Our cluster includes 40 nodes, running on top of PCI. We continuously run about 800 pods, and generate a lot of metrics as a result. Today, we’ll look at how (...)

Monitoring guidelines for OVH Observability https://www.ovh.com/fr/blog/monitoring-guidelines-for-ovh-observability/ https://www.ovh.com/fr/blog/monitoring-guidelines-for-ovh-observability/#respond Thu, 07 Mar 2019 12:19:08 +0000 https://blog.ovh.com/fr/blog/?p=14929 At the OVH Observability (formerly Metrics) team, we collect, process and analyse most of OVH’s monitoring data. It represents about 500M unique metrics, pushing data points at a steady rate of 5M per second. This data can be classified in two ways: host or application monitoring. Host monitoring is mostly based on hardware counters (CPU, memory, network, disk…) while application monitoring is based on the service and its scalability (requests, processing, business logic…). We provide this service for internal teams, who enjoy the same experience as our customers. Basically, our Observability service is SaaS with a compatibility layer (supporting InfluxDB, (...)

Continuous Delivery and Deployment Workflows with CDS https://www.ovh.com/fr/blog/continuous-delivery-and-deployment-workflows-with-cds/ https://www.ovh.com/fr/blog/continuous-delivery-and-deployment-workflows-with-cds/#respond Fri, 01 Mar 2019 13:38:13 +0000 https://blog.ovh.com/fr/blog/?p=14718 The CDS Workflow is a key feature of OVH CI/CD Platform. This structuring choice to add an additional concept above CI/CD pipelines and jobs is definitely an essential feature after more than three years of intense use.

Before going further on the explanation of a CDS workflow, we will make some reminders about the concepts of pipelines and jobs. Those concepts are based on the reference book 8 Principles of Continuous Delivery.

If you want to be part of the beta, please contact our support team. It allows you to use an external Microsoft Active Directory as the authentication source to access to the VMware vCenter server. The implementation of this feature has been made possible thanks to OVH’s DevOps team, who have developed an innovative and unique API that adds additional features to those offered by VMware. Indeed, it is not possible to configure identities’ sources via vCenter’s native API at the moment. In this post, we will (...)

The Unexpected Quest for Business Intelligence https://www.ovh.com/fr/blog/the-unexpected-quest-for-business-intelligence/ https://www.ovh.com/fr/blog/the-unexpected-quest-for-business-intelligence/#respond Thu, 28 Feb 2019 09:20:06 +0000 https://blog.ovh.com/fr/blog/?p=14522 Business Intelligence (BI) is the ability to collect substantial data from an information system to feed a Data Warehouse (DWH) or data lake. They usually provide a copy of the data that will be used for BI applications. Different strategies can be applied to feed a DWH. One such strategy is Change Data Capture (CDC), which is the ability to capture changing states from a database, and convert them to events that can be used for other purposes. Most databases are intended for OLTP purposes, and are well designed for this. Nonetheless, different use cases would require the same data with different access patterns. These use cases (big data, ETL, and stream processing, to name a few) mostly fall under the OLAP banner.

OVH, as a cloud provider, manages numerous databases, both for its customers and its own needs. Managing a database lifecycle always involves both keeping the infrastructure up to date, and remaining in synch with the development release cycle, to align the software with its database dependency. For example, an app might require MySQL 5.0, which could then be announced as EOL (End Of Life). In this case the app needs to be modified to support (let’s say) MySQL 5.5. We’re not reinventing the wheel here – this process has been managed by operations and dev teams for decades now.

This becomes trickier if you don’t have control over the application. For example, imagine a third party provides you with an application to ensure encrypted transactions. You have absolutely no control over this application, nor the associated database. Nonetheless, you still need the data from the database.

This blog post relates a similar example we encountered while building the OVH data lake, with the help of an in-house CDC development. This story takes place in early 2015, although I still think it’s worth sharing. 🙂

Getting external traffic into Kubernetes – ClusterIp, NodePort, LoadBalancer, and Ingress https://www.ovh.com/fr/blog/getting-external-traffic-into-kubernetes-clusterip-nodeport-loadbalancer-and-ingress/ https://www.ovh.com/fr/blog/getting-external-traffic-into-kubernetes-clusterip-nodeport-loadbalancer-and-ingress/#respond Fri, 22 Feb 2019 16:20:44 +0000 https://blog.ovh.com/fr/blog/?p=14674 For the last few months, I have been acting as Developer Advocate for the OVH Managed Kubernetes beta, following our beta testers, getting feedback, writing docs and tutorials, and generally helping to make sure the product matches our users' needs as closely as possible.

In the next few posts, I am going to tell you some stories about this beta phase. We'll be taking a look at feedback from some of our beta testers, technical insights, and some fun anecdotes about the development of this new service.

Today, we'll start with one of the most frequent questions I got during the early days of the beta: How do I route external traffic into my Kubernetes service? The question came up a lot as our customers began to explore Kubernetes, and when I tried to answer it, I realised that part of the problem was the sheer number of possible answers, and the concepts needed to understand them.

Yet these are not new concepts. The first Artificial Neural Network (ANN) was introduced in the 40s. So why all the recent interest around neural networks and Deep Learning?  We will explore this and other concepts in a series of blog posts on GPUs and Machine Learning. YABAIR – Yet Another Blog About Image Recognition In the 80s, I remember my father building character recognition for bank checks. He used primitives and derivatives around pixel darkness level.
